How to draw a sphere
-
I know this isn't exactly related to TPT, but...
Does anyone know of a way to draw a sphere programmatically?
(It would be preferable to just straight–out give me a function that could do it, assuming that the command to draw a quadrilateral is quad(x1, y1, z1, x2, y2, z2, x3, y3, z3, x4, y4, z4). I could also make do if it used triangles instead.)

It was,like, so hard! Like,I couldn't,like,watch,like,the,like, googling thingy, like. google the result, and like,I couldn't,like,figure out which,like,link to,like,click, so I just,like,clicked the first one! Like,I couldn't,like,read of that like,smart person talk,so I like,restarted the,like,computer because I,like, thought it was,like, my computer.But it,like,wasn't so I,like,went back to looking at,like,myself in the,like,mirror.

Thanks for giving me another link to add on to my ever-growing collection of sphere-drawing-related searches. You don't suppose that was the very first thing I did?

The general equation for a sphere is
(where r is the radius of the sphere)
so you can work from that. Alternatively, if you're using C++ and OpenGL, you could look at this StackOverflow answer or, if you use a version of GLUT then you could use glutSolidSphere as your starting point.
... and all that was obtained with one Google search and a bit of previous knowledge.Edited 3 times by boxmein. Last: 1st Dec 2013 -
I know all that. I literally looked at the first 50 results for 10 or so different Google searches.

I tried it, but it didn't have any shading (I'm using LuaGL, so that's pretty much required)
