Title: JBullet Mesh Collision Shapes
Post by: jon81 on June 14, 2011, 08:02:14 am

I would like to use a more detailed collision shape for the ground in my jpct app.

Instead of a flat plane I would like to use a mesh to represent the terrain.

From the Bullet documentation:

"For static world environment, a very efficient way to represent static triangle meshes is to use a btBvhTriangleMeshShape. This collision shape builds an internal acceleration structure from a btTriangleMesh or btStridingMeshInterface."

Can some one please post some example code showing how to take an Object3D (the ground mesh) and convert it to either a "btTriangleMesh" or a "btStridingMeshInterface" so that it can be used to create the btBvhTriangleMeshShape?

No idea about JBullet, but you can get polygon information from an Object3D by using the PolygonManager. Maybe that helps to recreate the structures needed for JBullet.
