Retrieves the triangle data for this mesh in a buffer of lengthgetIndexListSize().
Each face is a triplet of indices into the vertices array (getVertexList()). The
indices should always be used as a triangle list, with three indices per triangle. The result
can be passed as theindicesparameter toGLES20.glDrawElements(int, int, int, java.nio.Buffer).
The content of this buffer should not be modified by the caller.

Retrieves the number of triangle indices (represented bygetIndexList()) in this mesh.
The indices should always be used as a triangle list, with three indices per triangle. The
result can be passed as thecountparameter toGLES20.glDrawElements(int, int, int, java.nio.Buffer).
Retrieves the vertex coordinate data for this mesh. Each vertex is three float values, stored
in XYZ order. The total number of float values in the resultingFloatBufferis 3 *getVertexListSize().
The content of this buffer should not be modified by the caller.
