Look into the glu quadrics like gluSphere, gluCylinder, etc...

Try fooling around with sin() and cos() in a for statement. I can''t remember exactly how to do it, but it shouldnt be that hard to figure out on your own. The only hard part is connecting all the vertices together correctly

you can calculate points on sphere with:

x = radius*sin(a)*sin(b)
y = radius*cos(a)*sin(b)
z = radius*cos(b)

a [0..2PI]
b [-PI/2..PI/2]

then just connect the dots..

You should never let your fears become the boundaries of your dreams.
