<p>
Calculate the matrix using two vertices (which are preferably on the plane of the polygon and are possibly (but not necessarily) two vertices of the polygon).
<p>
The first vertex is seen as the origin and the second as the u-axis of the texture space coordinate system. The v-axis is calculated on the plane of the polygon and orthogonal to the given u-axis. The length of the u-axis and the v-axis is given as the 'len1' parameter.<p>
For example, if 'len1' is equal to 2 this means that texture will be tiled exactly two times between vertex 'v_orig' and 'v1'. I hope this explanation is clear since I can't seem to make it any clearer :-)
