* Experimental fix for tilted avatar capsule, Mantis #2905nlin2009-07-081-0/+3
| | | | | | | | | | | | | | | | | | | | | | | Set av_capsule_tilted to false in opensim.ini. Default is true, so there is no change in avatar behavior (and no breaking of existing content which relies on the tilted capsule). This commit straightens up the avatar capsule so it behaves consistently (e.g. same collision behavior against prims regardless of which direction the avatar is coming from; ability to fit through narrow doorways). Please note this introduces other side effects which have not been fixed. In particular: * The avatar frequently falls through the terrain if it is not flat, though the avatar behaves pretty well on flat terrain. This requires investigation of the ode terrain collider. * The apparent foot position of the avatar with respect to the ground is changed. This requires investigation of the avatar height/capsule height. Please consider this as work in progress.

| | | | | | | | Eat collision errors --- NOTE: this fix might be naive, it seems to have helped us getting to 81 avatars (whereas we'd crash with 20 before), but it sure would benefit from some check-over by a person skilled in the art of ODE physics.

| | | | | | | OpenSim.ini which will use meshes for collisions with simple prim shapes rather than internal ODE algorithms. This may help with Mantis #2905 and Mantis #3487 for those experimenting with capsule settings. Note that this will increase memory usage and region startup time.

* * fixes mantis 3259Teravus Ovares2009-03-071-0/+9
| | | | | * I'm concerned however that the 'minimum fly height' should really be implemented in ScenePresence and not in the specific physics plugin so that all of the physics plugins can take advantage of it and if desired, a person could swap out the 'minimum fly height' functionality with other functionality.

* Fixes Mantis #3260. Thank you kindly, MCortez for a patch that:Charles Krinke2009-03-061-0/+5
| | | | | | | | | | llSetHoverHeight() should not clamp the x/y position of an object the way MoveTo does, and it should recalculate the absolute height to hover at as an object moves to reflect the current ground/water height under it. Correctly implementing required adjusting the Physics interfaces and implementing at the physics plug-in level. The attached is a patch that correctly implements llSetHoverHeight() including updates to the ODE physics plug-in.

* This started as way to correct Mantis #3158, which I believe should be fixed ↵diva2009-02-151-1/+2
| | | | now. The flying status was temporarily being ignored, which caused the avie to drop sometimes -- there was a race condition. In the process it also fixes that annoying bug in basic physics where the avie would drop half-way to the ground upon region crossings (SetAppearance was missing). Additionally, a lot of child-agent-related code has been cleaned up; namely child agents are now consistently not added to physical scenes, and they also don't have appearances. All of that happens in MakeRoot, consistently.

* * Limit the total number of joints created per frame to the maximum possible ↵Teravus Ovares2009-02-081-12/+53
| | | | | | | | without causing a stack collision. * This fixes crashing on large sets of physical prims because of stack collisions (assuming you follow the directions on linux for starting ode with ulimit). After the maximum joints are created, objects will start to fall through the ground and be disabled. Not the best solution, but it's better then a crash caused by a stack collision with the process exceeding the maximum available memory/recursions per thread. * Make a clean region, make a stack of 5000 prim, 20 layers high. Make them physical, *SLOW*, but no crash.
* * Fixes colliding with the terrain lower then 0 and higher then 256mTeravus Ovares2009-02-081-11/+10
| | | | | | * The actual AABB of the heightfield on the Z is now determined by the minimum and maximum heightfield value in the terrain array (assuming it's a reasonable number). This might optimize collisions in simulators that have a small difference between minimum and maximum heightfield values.

* Mantis#2796. Thank you kindly, Gerhard for a patch that addresses:Charles Krinke2008-12-201-1/+19
| | | | | | | | | | | | | | On a call of llVolumeDetect(1) (or any other number !=0) volume detection is enabled. Together with VD, the phantom flag is set to the GUI. On a call of llVolumeDetect(0), vd detection is switched of again, also the phantom state is removed. On a call to llSetState(STATE_PHANTOM, false) while VD is active, also VD is switched off. The same is true for unchecking the phantom flag via GUI. This allows to take back VD without the need to script just by removing the phantom flag. Things missing in this patch: persistance of the volume-detection flag. This needs more discussion and will be included in another patch soon.
