Each tree is comprised of a simple 4 point, 2 polygon plane, mapped for the accompanying texture (transparency map included). The previews were obtained by copying numerous randomly scaled copies (about 3500) of the simple mesh. The complexity is determined only by the number of copies used. The mesh is included for simplicity's sake; you can of course create your own rectangular mesh; just be sure it is at a ratio of 2 units wide by 3 units tall (to match the diffuse map). Includes 4 texture (and corresponding transparency) maps of the more complex model pinetree03.zip, which were rendered from 4 different angles at a resolution of 500x750. Using these 4 maps, a greater variety in trees can be acheived than is shown here in the previews.
