Re: Debug draw triangles

I am working with btTriangleMesh and it's also drawn with lines. The problem here is that in btCollisionWorld.cpp, it should be m_debugDrawer->drawTriangle(wv0,wv1,wv2,m_color,1.0); instead of m_debugDrawer->drawLine(wv0,wv1,m_color); m_debugDrawer->drawLine(wv1,wv2,m_color); m_debugDrawer->drawLine...

Re: Does MultiSphereShape really support individual sphere scaling and repositioning?

Thanks again! I worked around those things now. But why are those features explicitly stated in the wiki and in Doxygen then? Should that be changed or do I get it wrong? Again with more context: http://bulletphysics.org/mediawiki-1.5.8/index.php/Collision_Shapes btMultiSphereShape A convex shape de...

Do pure intersection tests still need a collision margin?

Hi! I want to move objects (compound shape from cubes and btMultiSphereShape) on a predefined path through a static environment (btBvhTriangleMeshShape). All I care about is whether collision happened or not and where it happened if it happened. No resolving, no dynamics, only find intersections. If...

Re: Does MultiSphereShape really support individual sphere scaling and repositioning?

Hi, thanks for your answer! I am using bullet for static collision detection only, I just care about whether meshes intersect or not. I'm working with btCollisionWorld and btCollisionObject, no dynamics. What I mean is that btMultiSphereShape has the following members (all private): btAlignedObjectA...

Does MultiSphereShape really support individual sphere scaling and repositioning?

Hi! http://bulletphysics.org/mediawiki-1.5.8/index.php/Collision_Shapes says "Also since the spheres can be independently scaled in each of the 3 dimensions, ..." http://bulletphysics.com/Bullet/BulletFull/classbtMultiSphereShape.html says "It is possible to animate the spheres for deformation, but ...
