Detailed Description

The btTriangleMesh class is a convenience class derived from btTriangleIndexVertexArray, that provides storage for a concave triangle mesh. It can be used as data for the btBvhTriangleMeshShape. It allows either 32bit or 16bit indices, and 4 (x-y-z-w) or 3 (x-y-z) component vertices. If you want to share triangle/index data between graphics mesh and collision mesh (btBvhTriangleMeshShape), you can directly use btTriangleIndexVertexArray or derive your own class from btStridingMeshInterface. Performance of btTriangleMesh and btTriangleIndexVertexArray used in a btBvhTriangleMeshShape is the same.

void btTriangleMesh::addIndex ( int  index)

addIndex is an internal method, use addTriangle instead

void btTriangleMesh::addTriangle ( const btVector3 &  vertex0,
const btVector3 &  vertex1,
const btVector3 &  vertex2,
bool  removeDuplicateVertices = false 
)

By default addTriangle won't search for duplicate vertices, because the search is very slow for large triangle meshes. In general it is better to directly use btTriangleIndexVertexArray instead.

int btTriangleMesh::findOrAddVertex ( const btVector3 &  vertex,
bool  removeDuplicateVertices 
)

findOrAddVertex is an internal method, use addTriangle instead

bool btTriangleMesh::getUse32bitIndices ( ) const [inline]
