2012-11-03BulletSim: code rearrangementRobert Adams2-8/+6
2012-11-03BulletSim: Use Refresh/PostTaints to cause recomputing of constraint ↵Robert Adams1-29/+36
variables before the simulation step. Update logging and messages to properly name LinksetConstraints. Use UpdatePhysicalMassProperties to put the whole linkset mass into all the physical linkset members so they have the inertia to move the whole linkset.
2012-11-03BulletSim: add post taint taints and post step taints. The post taints ↵Robert Adams1-16/+122
operation is most useful and is used by linksets to build and rebuild only once before the simulation step.
2012-11-03BulletSim: remove unneeded parameter from Refresh().Robert Adams1-1/+1
2012-11-03BulletSim: centralize mass/inertia computation with ↵Robert Adams3-18/+38
UpdatePhysicalMassProperties() function. Didn't add setMassRaw because assignment with side effect is dirty.
2012-11-03BulletSim: rename constraint classes so they show up together alphabetically.Robert Adams3-6/+6
2012-11-03BulletSim: many small changes for vehicles simulation.Robert Adams1-31/+40
2012-11-03BulletSim: add ForEachMember(action) call for linkset.Robert Adams1-8/+28
2012-11-03BulletSim: Add activations after vehicle properties change. Problem was the ↵Robert Adams1-12/+62
vehicle was going to sleep while waiting for commands. Make AddAngularForce work the same way as AddForce -- accumulates values and pushes them once into Bullet.
2012-11-03BulletSim: correct spelling of Bullet call. It's 'swept' not 'sweep'.Robert Adams3-3/+7
2012-11-03BulletSim: Add banking and other new code to vechile dynamics. Add third ↵Robert Adams11-188/+323
party license and contributor in for for Aurora-Sim project for physics code.
2012-10-23BulletSim: fix problem with avatars sinking into the ground.Robert Adams4-15/+23
Change terrain activation state to DISABLE_SIMULATION for better performance.
2012-10-23BulletSim: minor change to insure avatar body recreation when shape changes.Robert Adams1-3/+3
2012-10-22BulletSim: remove chatty debug message.Robert Adams2-2/+2
2012-10-22BulletSim: fix bug that caused error (and a crash on 32 bit Linux) when mesh ↵Robert Adams8-35/+51
assets weren't already in the cache. Comment cleanups.
2012-10-22BulletSim: fix problem of not rebuilding shape by clearing last rebuild ↵Robert Adams2-2/+8
failed flag in BSPrim.ForceBodyShapeRebuild()
2012-10-22BulletSim: remove trailing spaces to make git happy.Robert Adams8-36/+36
2012-10-22BulletSim: encorporate UBit's suggestion to save a copy of mesh raw data.Robert Adams1-2/+1
2012-10-22BulletSim: Create LinkSet abstract class and sparate constraint based ↵Robert Adams3-319/+434
linksets into own subclass. Will eventually add manual movement linkset subclass.
2012-10-19BulletSim: add asset fetching so BulletSim works with new physics asset ↵Robert Adams4-165/+240
handling. Refactor some names to make them available for the asset tracking and fetching.
2012-10-19BulletSim: reorder avatar collision checking to eliminate double collision_end.Robert Adams6-35/+43
Various tweekings to avatar shape/mass/inertia/etc. Remove change from avatar radius to diameter. But still the avatar sinks. Collision_end now happens immediately rather than at the next subscription time.
2012-10-19BulletSim: change nonimal physics frame rate to 55 to give same numbers as ODE.Robert Adams6-52/+57
Change character scaling to represent size of capsule (diameter rather than radius) Modify create capsule call to pass radius and height. Eliminate errors when calculating shape inertia (should have some type checking).
2012-10-19BulletSim: remove code in ShapeCollection that hinted at shape sharing.Robert Adams5-161/+138
Add new function to ParameterDefn for calling BulletSimAPI to set values. Tweaking to BSCharacter parameter setting to try and have avatars stand.
2012-10-19BulletSim: Fix small problems with last patch: BSScene.World properly ↵Robert Adams3-11/+6
initialized and setting of C++ parameters commented out. Comments and logging added.
2012-10-19BulletSim: Update BSCharacter to use API2 interface.Robert Adams6-93/+250
Add capsule shape to BSShapeCollection(). Remember last updated values so inter frame diffs can be computed. Parameterize avatarStandingFriction and reduce to 10 from 999. The latter high value made avatars very hard to push. Set CCD parameters for prims and characters of specified.
2012-10-12BulletSim: only use native sphere shape if it is a sphere.Robert Adams1-1/+2
2012-10-11BulletSim: fix problem with some shapes (like cylinders) being implemented ↵Robert Adams1-1/+1
as cubes.
2012-10-11BulletSim: remove some unused API2 calls because they were removed from ↵Robert Adams2-14/+2
Bullet 2.81
2012-10-11BulletSim: normalize physics FPS to 45 (for real this time).Robert Adams1-2/+2
2012-10-11BulletSim: normalize physics FPS to 45.Robert Adams1-3/+4
2012-10-11BulletSim: Use full linkset mass when computing vehicle gravity force. Add ↵Robert Adams3-11/+16
taint-time specification to new AddForce().
2012-10-11BulletSim: Change defaults for constraint CFM and ERP to make large linksets ↵Robert Adams2-11/+8
more rigid. Remove mass calculation for terrain (it should stay a static object).
2012-10-11BulletSim: cosmetic changes (comments and renaming). Give mass to terrain to ↵Robert Adams7-52/+74
improve interactions.
2012-10-11BulletSim: Add Force* operations to objects to allow direct push to engine.Robert Adams7-29/+100
Update BSDynamics to use same (don't want to delay updates til next taint-time. Suppress queuing a taint update for position and orientation calls if value does not change. Move Bullet timing statistics call from C# back to C++ code. Throttle taints per simulation step and add parameter to set. By default, don't create hulls for physical objects. Add a parameter to turn on and off.
2012-10-11BulletSim: Fix crash when linking large physical linksets.Robert Adams8-102/+132
Properly remove and restore linkage constraints when upgrading a prim's mesh to a hull. Lots more debug logging. Definitions and use of Bullet structure dumping. Centralize detail logging so a Flush() can be added for debugging.
2012-10-02BulletSim: Make parameter value defaults match what should be the default ↵Robert Adams2-14/+14
and what is in OpenSimDefaults.ini. Comment and debug printout changes.
2012-10-02BulletSim: Add ForcePosition and ForceOrientation to BSPhysObject and to its ↵Robert Adams3-5/+64
children of BSPrim and BSCharacter.
2012-10-02BulletSim: Fix problem where box shapes were not being rebuilt if the shape ↵Robert Adams1-4/+6
type changed.
2012-10-02BulletSim: Fix linkset problem where delayed manipulations of child objects ↵Robert Adams1-10/+8
was using the child shape address at call time rather than the one created at taint time.
2012-10-02BulletSim: call ForcePosition and ForceOrientation in BSDynamics so there is ↵Robert Adams1-39/+57
no lag between what the vehicle code sees and what the physics engine is using.
2012-10-02BulletSim: fix the FloatOnWater code so avatars can normally go underwater.Robert Adams1-1/+1
2012-10-02BulletSim: impliment FloatOnWater OS function.Robert Adams3-22/+104
2012-10-02Correct my name in CONTRIBUTORS.txtRobert Adams1-35/+16
2012-10-02BulletSim: remove warnings for unused variables.Robert Adams3-14/+7
2012-09-28BulletSim: remember to release the physical body and shape when a prim is ↵Robert Adams2-16/+16
destroyed. This fixes many problems with physical linksets.
2012-09-27BulletSim: add separate runtime and taint-time linkset children lists to ↵Robert Adams3-80/+93
keep the creation of constraints separate from runtime.
2012-09-27BulletSim: rename some constraint variables to be consistant with other name ↵Robert Adams7-116/+231
use. Added callbacks for shape and body changes in GetBodyAndShape() so the linkset constraints can be picked up and restored. A better design might be to have a "prim shape changed" event. Think about that. Added constraint types to general constraint class.
2012-09-27BulletSim: remove the trailing spaces from lines to make git happierRobert Adams10-276/+275
2012-09-27BulletSim: remove the unused body management code from BSPrim. There is no ↵Robert Adams1-374/+0
going back now.
2012-09-27BulletSim: Fix linkset crash. Caused by the different body and shapeRobert Adams9-94/+182
pointers at runtime and at taint-time. Now passes the body into the taint. Vehicles zero inertia when active to eliminate Bullet's contribution to vehicle motion.
