Alright, so I have a problem. I need to figure out how to Tessellate a sphere. I am not quiet sure how to go about doing this, and the source code I have found doesn't explain well enough what the hell it is doing for me to copy the algorithm and not copy paste the code. This problem has stumped two masters students now in both Computer Science and Math. I figure it is a little bit of a long shot, but I might try here.

Anyone able to help me? Preferably before Sunday at midnight eastern time?

I don't really have the proper programming background for this, but just wondering, did you find this, and if so was it not enough? http://student.ulb.a...here/index.html
What is it that makes a complete stranger dive into an icy river to save a solid gold baby? Maybe we'll never know.

Basically my big issue with that is I can copy paste the code, but I have no idea how to handle the implementation of it. What I want to do is understand how its working and write the code as my own. If I take too much of it I am going to get a zero on the project I am working on instead of a 80->85.

I ended up figuring it out if anyone cared. Very complicated bullshit, but basically found a model that made sense. If you think of a sphere of being comprised of two rings, one that vertically rotates around the y axis and one that rotates horizontally around the y axis all points on the sphere are an intersection of those rings. Which goes to the formula y = r* sin(theta), x= r *cos(theta) * cos (phi), z = r * cos(theta) * sin(phi).

If anyone cared that is. I feel like I am smarter and more dumb for learning all this.

Yup. This is exactly what I didn't get into computer science for. Good job though dude.

I love CS for shit like this. It is like a giant puzzle I had to solve. Ridiculously fun.
