The second image gives you an overview of the | The second image gives you an overview of the elements in the coordinate array. Every triad of 32-bit numbers contains the x- y- and z-coordinate of a point. In this example every point exists in duplicate, so that you can only see 8 points. These points are needed to build up the mesh (triangles) for a door. | ||
