0eaccf881b Solaris was having problems with sqrtf and friends again. 
I changed sqrtf to sqrt in elbeem
in bullet2 I added defines found in floatpatch.h eventually
we should make a "floatpatch.h" that all of blender can use.

0110133cf7 Maybe not needed, I was running into some problems though 
and noticed dos line endings in a bunch of files so ran
dos2unix on everything in bullet2.

Erwin,  I noticed there are a few files that do not have
license info in them, couple of quick examples are: btDefaultMotionState.h
btHashMap.h btQuickprof.cpp
could you take a look at add where needed?   If you want I can give a list
of files I think should get it added  and or just add the standard one
say the one in src/btBulletCollisionCommon.h

808d6197cf add support for Bullet soft body constraints against a Bullet rigid body, as well as 'fixing' it. Just use the existing rigid body joint to use it. For now, it searches the closest node/vertex to the pivot. So you can use multiple constraints/joint to attach a cloth, soft body etc. 2008-09-30 23:34:25 +00:00

b6405b970c force collision bound type to be convex hull or concave triangle mesh for soft bodies 
set collision margin between soft and mesh back to .3, smaller is not useable (yet)

1e0cfcfd3a fixed some outstanding issues with Bullet soft bodies: 
1) re-allocate a pool allocator, if one of the soft body collision algorithms is larger than max pool element size
2) manage child shapes properly, and call RemoveReferences on the m_sparsesdf

a349a3201e * split collision lib into its subparts 
-This is to remedy long command-line troubles for scons/mingw users. Hopefully this goes ok on other platforms too :)

9d3c77ec62 support concave soft bodies, preliminary. could be used for cloth too. need vertex pinning/constraint attach to other objects. 2008-09-26 06:25:35 +00:00

a1bef84ea8 Allow Bullet soft bodies to be created using a AddObject actuator. Added a fake world coordinate system to game soft bodies, although the vertices are already in world space. 
Added Bullet/Gimpact concave collision detection to Blender. If your build system isn't updated yet, please add extern/bullet2/src/BulletCollision/Gimpact/*
This allows moving/dynamic concave triangle meshes (decomposing meshes into compound convex shapes, and using 'compound' shapes is still preferred)

3b09c0b0d5 Created a KX_SoftBodyDeformer for real-time soft bodies. 
Added SetDeformer/GetDeformer() to KX_GameObject.
Store mapping between graphics/soft body vertices (work-in-progress)
Real-time soft body integration is still very premature, but
for a quick preview, see this testfile:

d2d56e3058 bugfix for [#7006] Sleeping Objects losing Ghost Constraint 
Bullet logic bug in (de)activation/island management: deactivated 'fantom' objects do merge islands, in particular when connected by constraints. (fantom = object with collision detection but no collision response).

1c29d02305 BGE real-time soft bodies, step 2 / 3: create a btSoftBody. Next step is hooking up / deform graphics mesh and choose collision shape. 
Note: feature is still disabled.

7f293488d1 Upgrade to latest Bullet trunk, that is in sync with Blender/extern/bullet2. (except for one define 'WIN32_AVOID_SSE_WHEN_EMBEDDED_INSIDE_BLENDER') 
In case someone reads those SVN logs: you can enable some extra broadphase SSE optimizations by replacing WIN32_AVOID_SSE_WHEN_EMBEDDED_INSIDE_BLENDER by WIN32 in extern/bullet2/src/BulletCollision/BroadphaseCollision/btDbvt.h

Thanks to Benoit Bolsee for the upstream patch/contribution.
Removed some obsolete files, they were just intended for comparison/testing.

1926e84650 Finally upgraded to latest Bullet subversion, about to release 2.71. Some recent changes in extern/bullet2 need to be re-applied, will check with Benoit. Ray tests in 0_FPS_Template.blend is broken, didn't figure out why yet. 
HELP BUILD SYSTEM MAINTAINERS: Please help with updating all build systems: the newly added files need to be added. Note that the src/SoftBody has been added for future extension of real-time soft bodies.

fd877543d1 New: Collision Modifier and Cloth can be at any position on the modifier stack. BUT everytime the vertices count change, they will free themselves and internal build new (they rely on vertex count). Should be no problem anymore with e.g. subsurf modifier before collision modifier (tested).

cf04786a8b Removed -mpowerpc -mtune=G4 from several SCons files, so it will work on 
either PPC or Intel architectures under OSX.  These options should be
inherited properly from the rest of the OSX SCons build system.

Erwin Coumans
44d16f0562 Added refactored Bullet 2.x library. Important: these files are not part of the Blender build yet. First, the integration will be updated to make use of the new Bullet version. Then all build systems needs to be updated. 
The refactoring didn't leave a single file the same, all filenames and classes have bt prefix, methodnames start with lowercase, a single headerfile can be included, and also a single include path.
Plan is to make use of this Bullet 2.x version in extern/bullet2 within the coming weeks, then extern/bullet can be discarded/ignored/content removed.
