[ODE] triangle mesh geometry class

[Pawel S]

Here is what I use. Very plain and simple.

// defs
typedef int tVertIndexTriangle[ 3 ];
typedef double tVertexAsArray[ 3 ];

typedef struct
{
	int m_iNumVerts;
	int m_iNumTris;
	tVertexAsArray* m_pVerts;
	tVertIndexTriangle * m_pTris;
} tTriMesh;


// vars

tTriMesh TerrainMesh;
dTriMeshDataID TerrainMeshDataID;
dGeomID GeomTerrain;


// initialize

// TerrainMesh is filled with data by a ObjectLoader somewhere else
TerrainMeshDataID = dGeomTriMeshDataCreate();
dGeomTriMeshDataBuildDouble(
	TerrainMeshDataID,          // dTriMeshDataID
	TerrainMesh.m_pVerts,       // const void*  a pointer to an array
	                            // holding the vertices
	sizeof( tVertexAsArray ),   // int          how large is the
	                            // memory footprint of one vertex
	TerrainMesh.m_iNumVerts,    // int          how many vertices
	TerrainMesh.m_pTris,        // const void*  a pointer to an array
	                            // holding the indices to vertices
	TerrainMesh.m_iNumTris * 3, // int          how many vertex
	                            // indices total in the mesh
	sizeof( uint ) * 3          // int          how large is the
	                            // memory footprint of an array
	                            // holding the indices to vertices in
	                            // a triangle
);
GeomTerrain = dCreateTriMesh( WorldSpace, TerrainMeshDataID, 0, 0, 0 );
