Extract points for collision shape

[Sinthoras]

Hello everyone,

Im trying around with OGRE and BulletPhysics and right now I would like to created some good collision shapes for my graphic objects. To do that I need to extract some points from the mesh surface (I create the meshes with blender) and the question is, how can I get these surface points? Any ideas?

Greetings

A mesh consists of one or more sub-meshes. Each sub-mesh contains a vertex declaration - that's where you can get the vertices (points) you need. But don't forget that all vertices usually reside in a shared (by all sub-meshes) vertex buffer and then index buffers are used to point exactly which vertices compose sub-mesh triangles.
