Dear all,
Hi, i’m trying to draw a circle and sphere with OpenGL. But i don’t know how. Could anyone drop me some hints plase~ thanks.
I looked at some of the sites that talke about opengl, but most of them only talk about cubes and triangles, but not spheres… (~_~) Even the book that i have, they use GLUT instead…
If any of you can drop me some hits, that would be great, once again, Thanks~~
(by the way, i need it in a kinda of hurry, for a project, thanks~~~ )
Under the glu library (glu.h):
gluSphere, gluDisk (Circle)
Under the glut library (glut.h):
glutSolidSphere, glutWireSphere.
Another option for drawing a circle is the use the math function for a circle using sin/cos.

(do they do support for cube too? or this one have to go to GLUT? coz the code isn’t for me, is for my friend. If i can do it with cubes…etc too, then the code wouldn’t look so mess, he would be easier to follow… )
Once agin, Thanks~~~~

First you should get your friend on this web site to help him learn.
glut is good for simple quick objects, but has some limitation.
some of the other shapes: Cube, Cone, Torus, Dodecahedron, Teapot.
glutSolid"shape" or glutWire"shape"

This save me big time~~ Thanks (^_^)

Fair enough possibly with the sphere, But surely you can see that a cube can easily be constructed from squares, and each square can be made of 2 triangles…
