erwin.coumans d221d3be8d Update btSoftBodyCollisionShape to set m_shapeType 2008-09-30 00:05:44 +00:00
erwin.coumans e590f4a721 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
 2008-09-26 23:39:17 +00:00
erwin.coumans 682a0a1b90 fixed btSoftBodyConcaveCollisionAlgorithm, wrong bounding box transformation

- Fixed a performance issues reported by 'reltham'
- Added btDbvtBroadphase::optimize() for people who want good performances right away or don't do dynamics.
- fixed compilation issues when DBVT_BP_PROFILE was set.

btSoftBody:
- Fixed singular matrix issues related to polar decomposition (flat meshes).

DemoApplication:
- Shadows (enable/disable through 'g' or DemoApplication::setShadows(bool)).
- Texture can be enable/disable through 'u'

CDFramework:
- fixed compilation issues.
