3-d Tesselation Tutorial
Here is my first attempt at a 3-d tess tutorial by pictures. The first picture up top is the front and the second is the tesselation backlit.
1st precrease 32nds is a good idea.
Do step three on the other two sides. Then you continue doing this, but not to the triangles next to it. Look below and you can see the edges of which triangles to work on.
Now complete all the triangles not done before like above and you should have the tesselation that appears at the top of this post.
