11/**
12 * 3D point.
13 *
14 * The name is "Point" instead of "Vector" since a vector is N-dimensional, whereas a point is an implicit "vector of dimension 3".
15 * So the choice was between "Point" and "Vector3", the first one looked better (IMHO).
16 *
17 * Some people, then, use a typedef to handle both points & vectors using the same class: typedef Point Vector3;
18 * This is bad since it opens the door to a lot of confusion while reading the code. I know it may sounds weird but check this out:
19 *
20 * \code
21 * Point P0,P1 = some 3D points;
22 * Point Delta = P1 - P0;
23 * \endcode
24 *
25 * This compiles fine, although you should have written:
26 *
27 * \code
28 * Point P0,P1 = some 3D points;
29 * Vector3 Delta = P1 - P0;
30 * \endcode
31 *
32 * Subtle things like this are not caught at compile-time, and when you find one in the code, you never know whether it's a mistake
33 * from the author or something you don't get.
34 *
35 * One way to handle it at compile-time would be to use different classes for Point & Vector3, only overloading operator "-" for vectors.
36 * But then, you get a lot of redundant code in thoses classes, and basically it's really a lot of useless work.
37 *
38 * Another way would be to use homogeneous points: w=1 for points, w=0 for vectors. That's why the HPoint class exists. Now, to store
39 * your model's vertices and in most cases, you really want to use Points to save ram.

11/**
12 * Revisited Radix Sort.
13 * This is my new radix routine:
14 * - it uses indices and doesn't recopy the values anymore, hence wasting less ram
15 * - it creates all the histograms in one run instead of four
16 * - it sorts words faster than dwords and bytes faster than words
17 * - it correctly sorts negative floating-point values by patching the offsets
18 * - it automatically takes advantage of temporal coherence
19 * - multiple keys support is a side effect of temporal coherence
20 * - it may be worth recoding in asm... (mainly to use FCOMI, FCMOV, etc) [it's probably memory-bound anyway]
21 *
22 * History:
23 * - 08.15.98: very first version
24 * - 04.04.00: recoded for the radix article
25 * - 12.xx.00: code lifting
26 * - 09.18.01: faster CHECK_PASS_VALIDITY thanks to Mark D. Shattuck (who provided other tips, not included here)
27 * - 10.11.01: added local ram support
28 * - 01.20.02: bugfix! In very particular cases the last pass was skipped in the float code-path, leading to incorrect sorting......
29 * - 01.02.02: - "mIndices" renamed => "mRanks". That's a rank sorter after all.
30 * - ranks are not "reset" anymore, but implicit on first calls
31 * - 07.05.02: - offsets rewritten with one less indirection.
32 * - 11.03.02: - "bool" replaced with RadixHint enum
33 *

41/*
42To do:
43 - add an offset parameter between two input values (avoid some data recopy sometimes)
44 - unroll ? asm ?
45 - 11 bits trick & 3 passes as Michael did
46 - prefetch stuff the day I have a P3
47 - make a version with 16-bits indices ?

19/**
20 * An hybrid collision model.
21 *
22 * The problem :
23 *
24 * Opcode really shines for mesh-mesh collision, especially when meshes are deeply overlapping
25 * (it typically outperforms RAPID in those cases).
26 *
27 * Unfortunately this is not the typical scenario in games.
28 *
29 * For close-proximity cases, especially for volume-mesh queries, it's relatively easy to run faster
30 * than Opcode, that suffers from a relatively high setup time.
31 *
32 * In particular, Opcode's "vanilla" trees in those cases -can- run faster. They can also use -less-
33 * memory than the optimized ones, when you let the system stop at ~10 triangles / leaf for example
34 * (i.e. when you don't use "complete" trees). However, those trees tend to fragment memory quite a
35 * lot, increasing cache misses : since they're not "complete", we can't predict the final number of
36 * nodes and we have to allocate nodes on-the-fly. For the same reasons we can't use Opcode's "optimized"
37 * trees here, since they rely on a known layout to perform the "optimization".
38 *
39 * Hybrid trees :
40 *
41 * Hybrid trees try to combine best of both worlds :
42 *
43 * - they use a maximum limit of 16 triangles/leaf. "16" is used so that we'll be able to save the
44 * number of triangles using 4 bits only.
45 *
46 * - they're still "complete" trees thanks to a two-passes building phase. First we create a "vanilla"
47 * AABB-tree with Opcode, limited to 16 triangles/leaf. Then we create a *second* vanilla tree, this
48 * time using the leaves of the first one. The trick is : this second tree is now "complete"... so we
49 * can further transform it into an Opcode's optimized tree.
50 *
51 * - then we run the collision queries on that standard Opcode tree. The only difference is that leaf
52 * nodes contain indices to leaf nodes of another tree. Also, we have to skip all primitive tests in
53 * Opcode optimized trees, since our leaves don't contain triangles anymore.
54 *
55 * - finally, for each collided leaf, we simply loop through 16 triangles max, and collide them with
56 * the bounding volume used in the query (we only support volume-vs-mesh queries here, not mesh-vs-mesh)
57 *
58 * All of that is wrapped in this "hybrid model" that contains the minimal data required for this to work.
59 * It's a mix between old "vanilla" trees, and old "optimized" trees.
60 *
61 * Extra advantages:
62 *
63 * - If we use them for dynamic models, we're left with a very small number of leaf nodes to refit. It
64 * might be a bit faster since we have less nodes to write back.
65 *
66 * - In rigid body simulation, using temporal coherence and sleeping objects greatly reduce the actual
67 * influence of one tree over another (i.e. the speed difference is often invisible). So memory is really
68 * the key element to consider, and in this regard hybrid trees are just better.
69 *
70 * Information to take home:
71 * - they use less ram
72 * - they're not slower (they're faster or slower depending on cases, overall there's no significant
73 * difference *as long as objects don't interpenetrate too much* - in which case Opcode's optimized trees
74 * are still notably faster)

32/**
33 * This class is an interface between us and user-defined meshes. Meshes can be defined in a lot of ways, and here we
34 * try to support most of them.
35 *
36 * Basically you have two options:
37 * - callbacks, if OPC_USE_CALLBACKS is defined in OPC_Settings.h.
38 * - else pointers.
39 *
40 * If using pointers, you can also use strides or not. Strides are used when OPC_USE_STRIDE is defined.
41 *
42 *
43 * CALLBACKS:
44 *
45 * Using callbacks is the most generic way to feed OPCODE with your meshes. Indeed, you just have to give
46 * access to three vertices at the end of the day. It's up to you to fetch them from your database, using
47 * whatever method you want. Hence your meshes can lie in system memory or AGP, be indexed or not, use 16
48 * or 32-bits indices, you can decompress them on-the-fly if needed, etc. On the other hand, a callback is
49 * called each time OPCODE needs access to a particular triangle, so there might be a slight overhead.
50 *
51 * To make things clear: geometry & topology are NOT stored in the collision system,
52 * in order to save some ram. So, when the system needs them to perform accurate intersection
53 * tests, you're requested to provide the triangle-vertices corresponding to a given face index.
54 *
55 * Ex:
56 *
57 * \code
58 * static void ColCallback(udword triangle_index, VertexPointers& triangle, udword user_data)
59 * {
60 * // Get back Mesh0 or Mesh1 (you also can use 2 different callbacks)
61 * Mesh* MyMesh = (Mesh*)user_data;
62 * // Get correct triangle in the app-controlled database
63 * const Triangle* Tri = MyMesh->GetTriangle(triangle_index);
64 * // Setup pointers to vertices for the collision system
65 * triangle.Vertex[0] = MyMesh->GetVertex(Tri->mVRef[0]);
66 * triangle.Vertex[1] = MyMesh->GetVertex(Tri->mVRef[1]);
67 * triangle.Vertex[2] = MyMesh->GetVertex(Tri->mVRef[2]);
68 * }
69 *
70 * // Setup callbacks
71 * MeshInterface0->SetCallback(ColCallback, udword(Mesh0));
72 * MeshInterface1->SetCallback(ColCallback, udword(Mesh1));
73 * \endcode
74 *
75 * Of course, you should make this callback as fast as possible. And you're also not supposed
76 * to modify the geometry *after* the collision trees have been built. The alternative was to
77 * store the geometry & topology in the collision system as well (as in RAPID) but we have found
78 * this approach to waste a lot of ram in many cases.
79 *
80 *
81 * POINTERS:
82 *
83 * If you're internally using the following canonical structures:
84 * - a vertex made of three 32-bits floating point values
85 * - a triangle made of three 32-bits integer vertex references
86 * ...then you may want to use pointers instead of callbacks. This is the same, except OPCODE will directly
87 * use provided pointers to access the topology and geometry, without using a callback. It might be faster,
88 * but probably not as safe. Pointers have been introduced in OPCODE 1.2.
89 *
90 * Ex:
91 *
92 * \code
93 * // Setup pointers
94 * MeshInterface0->SetPointers(Mesh0->GetFaces(), Mesh0->GetVerts());
95 * MeshInterface1->SetPointers(Mesh1->GetFaces(), Mesh1->GetVerts());
96 * \endcode
97 *
98 *
99 * STRIDES:
100 *
101 * If your vertices are D3D-like entities interleaving a position, a normal and/or texture coordinates
102 * (i.e. if your vertices are FVFs), you might want to use a vertex stride to skip extra data OPCODE
103 * doesn't need. Using a stride shouldn't be notably slower than not using it, but it might increase
104 * cache misses. Please also note that you *shouldn't* read from AGP or video-memory buffers !
105 *
106 *
107 * In any case, compilation flags are here to select callbacks/pointers/strides at compile time, so
108 * choose what's best for your application. All of this has been wrapped into this MeshInterface.

19/**
20 * The main collision wrapper, for all trees. Supported trees are:
21 * - Normal trees (2*N-1 nodes, full size)
22 * - No-leaf trees (N-1 nodes, full size)
23 * - Quantized trees (2*N-1 nodes, half size)
24 * - Quantized no-leaf trees (N-1 nodes, half size)
25 *
26 * Usage:
27 *
28 * 1) Create a static mesh interface using callbacks or pointers. (see OPC_MeshInterface.cpp).
29 * Keep it around in your app, since a pointer to this interface is saved internally and
30 * used until you release the collision structures.
31 *
32 * 2) Build a Model using a creation structure:
33 *
34 * \code
35 * Model Sample;
36 *
37 * OPCODECREATE OPCC;
38 * OPCC.IMesh = ...;
39 * OPCC.Rules = ...;
40 * OPCC.NoLeaf = ...;
41 * OPCC.Quantized = ...;
42 * OPCC.KeepOriginal = ...;
43 * bool Status = Sample.Build(OPCC);
44 * \endcode
45 *
46 * 3) Create a tree collider and set it up:
47 *
48 * \code
49 * AABBTreeCollider TC;
50 * TC.SetFirstContact(...);
51 * TC.SetFullBoxBoxTest(...);
52 * TC.SetFullPrimBoxTest(...);
53 * TC.SetTemporalCoherence(...);
54 * \endcode
55 *
56 * 4) Perform a collision query
57 *
58 * \code
59 * // Setup cache
60 * static BVTCache ColCache;
61 * ColCache.Model0 = &Model0;
62 * ColCache.Model1 = &Model1;
63 *
64 * // Collision query
65 * bool IsOk = TC.Collide(ColCache, World0, World1);
66 *
67 * // Get collision status => if true, objects overlap
68 * BOOL Status = TC.GetContactStatus();
69 *
70 * // Number of colliding pairs and list of pairs
71 * udword NbPairs = TC.GetNbPairs();
72 * const Pair* p = TC.GetPairs()
73 * \endcode
74 *
75 * 5) Stats
76 *
77 * \code
78 * Model0.GetUsedBytes() = number of bytes used for this collision tree
79 * TC.GetNbBVBVTests() = number of BV-BV overlap tests performed during last query
80 * TC.GetNbPrimPrimTests() = number of Triangle-Triangle overlap tests performed during last query
81 * TC.GetNbBVPrimTests() = number of Triangle-BV overlap tests performed during last query
82 * \endcode
83 *

459// Quantization notes:
460// - We could use the highest bits of mData to store some more quantized bits. Dequantization code
461// would be slightly more complex, but number of overlap tests would be reduced (and anyhow those
462// bits are currently wasted). Of course it's not possible if we move to 16 bits mData.
463// - Something like "16 bits floats" could be tested, to bypass the int-to-float conversion.
464// - A dedicated BV-BV test could be used, dequantizing while testing for overlap. (i.e. it's some
465// lazy-dequantization which may save some work in case of early exits). At the very least some
466// muls could be saved by precomputing several more matrices. But maybe not worth the pain.
467// - Do we need to dequantize anyway? Not doing the extents-related muls only implies the box has
468// been scaled, for example.
469// - The deeper we move into the hierarchy, the smaller the extents should be. May not need a fixed
470// number of quantization bits. Even better, could probably be best delta-encoded.

19/**
20 * Contains a ray-vs-tree collider.
21 * This class performs a stabbing query on an AABB tree, i.e. does a ray-mesh collision.
22 *
23 * HIGHER DISTANCE BOUND:
24 *
25 * If P0 and P1 are two 3D points, let's define:
26 * - d = distance between P0 and P1
27 * - Origin = P0
28 * - Direction = (P1 - P0) / d = normalized direction vector
29 * - A parameter t such as a point P on the line (P0,P1) is P = Origin + t * Direction
30 * - t = 0 --> P = P0
31 * - t = d --> P = P1
32 *
33 * Then we can define a general "ray" as:
34 *
35 * struct Ray
36 * {
37 * Point Origin;
38 * Point Direction;
39 * };
40 *
41 * But it actually maps three different things:
42 * - a segment, when 0 <= t <= d
43 * - a half-line, when 0 <= t < +infinity, or -infinity < t <= d
44 * - a line, when -infinity < t < +infinity
45 *
46 * In Opcode, we support segment queries, which yield half-line queries by setting d = +infinity.
47 * We don't support line-queries. If you need them, shift the origin along the ray by an appropriate margin.
48 *
49 * In short, the lower bound is always 0, and you can setup the higher bound "d" with RayCollider::SetMaxDist().
50 *
51 * Query |segment |half-line |line
52 * --------|-------------------|---------------|----------------
53 * Usages |-shadow feelers |-raytracing |-
54 * |-sweep tests |-in/out tests |
55 *
56 * FIRST CONTACT:
57 *
58 * - You can setup "first contact" mode or "all contacts" mode with RayCollider::SetFirstContact().
59 * - In "first contact" mode we return as soon as the ray hits one face. If can be useful e.g. for shadow feelers, where
60 * you want to know whether the path to the light is free or not (a boolean answer is enough).
61 * - In "all contacts" mode we return all faces hit by the ray.
62 *
63 * TEMPORAL COHERENCE:
64 *
65 * - You can enable or disable temporal coherence with RayCollider::SetTemporalCoherence().
66 * - It currently only works in "first contact" mode.
67 * - If temporal coherence is enabled, the previously hit triangle is cached during the first query. Then, next queries
68 * start by colliding the ray against the cached triangle. If they still collide, we return immediately.
69 *
70 * CLOSEST HIT:
71 *
72 * - You can enable or disable "closest hit" with RayCollider::SetClosestHit().
73 * - It currently only works in "all contacts" mode.
74 * - If closest hit is enabled, faces are sorted by distance on-the-fly and the closest one only is reported.
75 *
76 * BACKFACE CULLING:
77 *
78 * - You can enable or disable backface culling with RayCollider::SetCulling().
79 * - If culling is enabled, ray will not hit back faces (only front faces).

2This is a copy of the OPCODE collision detection library by Pierre Terdiman.
3See http://www.codercorner.com/Opcode.htm for more information, and read
4the ReadMe.txt in this directory.

6If you want to use the TriList (triangle mesh) geometry class in ODE, the
7OPCODE library must be compiled. If you are using the autotools support to
8compile ODE, you just have to specify --with-trimesh=opcode when calling ./configure.
9
10This code was originally written for and compiled on windows, but it has been
11ported so that it should compile under unix/gcc too. Your mileage may vary.

2 OPCODE distribution 1.3 (june 2003)
3 -----------------------
4
5 New in Opcode 1.3:
6 - fixed the divide by 0 bug that was happening when all centers where located on a coordinate axis (thanks to Jorrit T)
7 - linearized "complete" vanilla AABB trees
8 - ANSI-compliant "for" loops (for the ones porting it to Linux...)
9 - callbacks & pointers moved to mesh interface
10 - support for triangle & vertex strides
11 - optimized the sphere-triangle overlap code a bit
12 - dynamic trees (refit)
13 - more builders
14 - ValidateSubdivision in builders
15 - LSS collider
16 - primitive-bv tests can now be skipped in most volume queries
17 - temporal coherence now also works for airborne objects
18 - temporal coherence completed for boxes / all contacts, LSS, etc
19 - ray-collider now uses a callback
20 - some common "usages" have been introduced (only picking for now)
21 - SPLIT_COMPLETE removed (now implicitely using mLimit = 1)
22 - hybrid collision models
23 - sweep-and-prune code added, moved from my old Z-Collide lib
24 - it now works with meshes made of only 1 triangle (except in mesh-mesh case!)
25
26 Disclaimer:
27
28 - I forced myself to actually *do* the release today no matter what. Else it would never have been done. That's
29 why the code may not be very polished. I also removed a *lot* of things (more usages, distance queries, etc...)
30 that weren't ready for prime-time (or that were linked to too many of my supporting libs)
31
32 - Some comments may also be obsolete here and there. The old User Manual for Opcode 1.2 may not fit version 1.3
33 either, since there's a new "mesh interface" to support strides, etc.
34
35 - Everything in the "Ice" directory has been hacked out of my engine and edited until everything compiled. Don't
36 expect anything out there to be cute or something. In particular, some CPP files are not even included when not
37 needed, so you can expect some linker errors if you try messing around with them...
38
39 Otherwise, it should be just like previous version, only better. In particular, hybrid models can be very
40 memory-friendly (sometimes using like 10 times less ram than the best trees from version 1.2). The possible
41 speed hit is often invisible (if it even exists), especially using temporal coherence in "all contacts" mode.
42 (Admittedly, this depends on your particular usage pattern / what you do on collided triangles).
43
44 The sweep-and-prune code is similar to the "vanilla" version found in V-Collide (but that one's better IMHO...)
45 The simple "radix" version is often just as good, see for yourself.
46
47 OPCODE distribution 1.2 (august 2002)
48 -----------------------
49
50 New in Opcode 1.2:
51 - new VolumeCollider base class
52 - simplified callback setup
53 - you can now use callbacks or pointers (setup at compile time)
54 - destination array not needed anymore in the RayCollider (faster in-out tests)
55 - renamed classes: AABBRayCollider => RayCollider, AABBSphereCollider => SphereCollider
56 - the sphere query now only returns a list of faces (extra info discarded). On the other hand it's a lot faster.
57 - OBB, AABB and planes queries. Original OBB and AABB queries contributed by Erwin de Vries.
58 - cosmetic changes in OPC_BoxBoxOverlap.h contributed by Gottfried Chen
59 - some inlining problems fixed
60 - faster ray-mesh tests using the separating axis theorem
61 - new split value in AABB tree construction (contributed by Igor Kravtchenko). Provides faster queries most of the time.
62 - improved temporal coherence for sphere & AABB queries (works in "All contacts" mode)
63
64 Notes:
65
66 - Everything in the "Ice code" directory (in VC++) is basically copy-pasted from my engine, with a lot
67 of code removed until there was no link error anymore. Don't expect those files to be cute or anything,
68 they've never been meant to be released and they're often updated/modified/messy.
69 - Some experimental features have been removed as well. Else I would never have released the 1.2...
70 - Not as polished/optimal as I would like it to be, but that's life. I promised myself to release it
71 before october 2002 (one YEAR later ?!).... That's the only reason why it's there.
72 - Some people reported ColDet was faster. Uh, come on. They were using Opcode in
73 "All contacts" mode whereas ColDet was doing "first contact"...
74
75 OPCODE distribution 1.1 (october 2001)
76 -----------------------
77
78 New in Opcode 1.1:
79 - stabbing queries
80 - sphere queries
81 - abtract base class for colliders
82 - settings validation methods
83 - compilation flags now grouped in OPC_Settings.h
84 - smaller files, new VC++ virtual dirs (cleaner)
85
86 Notes:
87
88 - "override(baseclass)" is a personal cosmetic thing. It's the same as "virtual", but provides more info.
89 - I code in 1600*1200, so some lines may look a bit long..
90 - This version is not as polished as the previous one due to lack of time. The stabbing & sphere queries
91 can still be optimized: for example by trying other atomic overlap tests. I'm using my first ray-AABB
92 code, but the newer one seems better. Tim Schröder's one is good as well. See: www.codercorner.com/RayAABB.cpp
93 - The trees can easily be compressed even more, I save this for later (lack of time, lack of time!)
94 - I removed various tests before releasing this one:
95 - a separation line, a.k.a. "front" in QuickCD, because gains were unclear
96 - distance queries in a PQP style, because it was way too slow
97 - support for deformable models, too slow as well
98 - You can easily use Opcode to do your player-vs-world collision detection, in a Nettle/Telemachos way.
99 If someone out there wants to donate some art / level for the cause, I'd be glad to release a demo. (current
100 demo uses copyrighted art I'm not allowed to spread)
101 - Sorry for the lack of real docs and/or solid examples. I just don't have enough time.
102
103 OPCODE distribution 1.0 (march 2001)
104 -----------------------
105
106 - First release
107
108 ===============================================================================
109
110 WHAT ?
111
112 OPCODE means OPtimized COllision DEtection.
113 So this is a collision detection package similar to RAPID. Here's a
114 quick list of features:
115
116 - C++ interface, developed for Windows systems using VC++ 6.0
117 - Works on arbitrary meshes (convex or non-convex), even polygon soups
118 - Current implementation uses AABB-trees
119 - Introduces Primitive-BV overlap tests during recursive collision queries (whereas
120 standard libraries only rely on Primitive-Primitive and BV-BV tests)
121 - Introduces no-leaf trees, i.e. collision trees whose leaf nodes have been removed
122 - Supports collision queries on quantized trees (decompressed on-the-fly)
123 - Supports "first contact" or "all contacts" modes (ā la RAPID)
124 - Uses temporal coherence for "first contact" mode (~10 to 20 times faster, useful
125 in rigid body simulation during bisection)
126 - Memory footprint is 7.2 times smaller than RAPID's one, which is ideal for console
127 games with limited ram (actually, if you use the unmodified RAPID code using double
128 precision, it's more like 13 times smaller...)
129 - And yet it often runs faster than RAPID (according to RDTSC, sometimes more than 5
130 times faster when objects are deeply overlapping)
131 - Performance is usually close to RAPID's one in close-proximity situations
132 - Stabbing, planes & volume queries (sphere, AABB, OBB, LSS)
133 - Sweep-and-prune
134 - Now works with deformable meshes
135 - Hybrid trees
136
137
138 What it can be used for:
139 - standard mesh-mesh collision detection (similar to RAPID, SOLID, QuickCD, PQP, ColDet...)
140 - N-body collisions (similar to V-Collide)
141 - camera-vs-world collisions (similar to Telemachos/Paul Nettle/Stan Melax articles)
142 - shadow feelers to speed up lightmap computations
143 - in-out tests to speed up voxelization processes
144 - picking
145 - rigid body simulation
146 - view frustum culling
147 - etc
148
149 WHY ?
150
151 - Because RAPID uses too many bytes.
152 - Because the idea was nice...
153
154 WHEN ?
155
156 It's been coded in march 2001 following a thread on the GD-Algorithms list.

6> >(2) How is the receiving geometry for the shadow decided?
7>
8> I wrote about an LSS-test but actually performing a new VFC test (from the
9> light's view) is the same. In both cases, here's a trick to take advantage
10> of temporal coherence : test the world against a slightly larger than
11> necessary LSS or frustum. Keep the list of touched surfaces. Then next
12> frame, if the new volume is still contained within the previous one used

14> the query, you can reuse the same list immediately. Actually it's a bit
15> similar to what you did in your sphere-tree, I think. Anyway, now the
16O(log
17> N) VFC is O(1) for some frames. It's not worth it for the "real" VFC, but
18> when you have N virtual frustum to test to drop N shadows, that's another
19> story.
20>
21> Two downsides:
22> - You need more ram to keep track of one list of meshes / shadow, but
23> usually it's not a lot.
24> - By using a larger volume for the query you possibly touch more
25> faces/surfaces, which will be rendered in the shadow pass. Usually it's
26not
27> a problem either since rendering is simply faster than geometric queries
28> those days. But of course, "your mileage may vary".
29>
