/**
 * This class is used to describe the vertices and faces of a triangular mesh.
 * A TriangleVertexArray represents a continuous array of vertices and indexes
 * of a triangular mesh. When you create a TriangleVertexArray, no data is copied
 * into the array. It only stores pointer to the da. The purpose is to allow
 * the user to share vertices data between the physics engine and the rendering
 * part. Therefore, make sure that the data pointed by a TriangleVertexArray
 * remain valid during the TriangleVertexArray life.
