void vertexCount(int count)
If this geometry uses vertex pulling or non-indexed drawing, Set the number of vertices to be drawn of this geometry by the rendererDefault is -1, which means all vertices are drawn. Values will be clamped to the actual number of vertices in the geometry.
void generateTangents()
Generate tangents assuming default vertex attribute locations: position=0, normal=1, uv=2, tangent=3. Tangents are written to location = 3.Indices are supported but optional. Call *after* all other attribute data and indices have been supplied.
