Skyboxes... This time with a bit more experience...

[dangerdoc]

Hey guys, I have asked this question in the past and couldn't understand it, or any of the other questions I got answers from, but I have a general Idea of how I would make a skybox, I just want to know how I would render a sphere object, one vertex at a time, so I could do something to change the color of the vertices based on their coordinates. Can I run a function on Spheres that calls my function for each vertex, or do I have to add the object myself from scratch? I understand that I could use shaders, but I absolutely can not grasp shaders... Seems like a bunch of math to me, with nothing behind it (I know there is something behind it...)

Can you correct my solution/give me different one? Thanks!
