can you tell me how to generate sphere vertices? i want an array with vertices so i can edit the mesh like in 3ds max, so i can´t use the glu tools. thx --=[[TheMatrixXXX]]=--

thx for your answers
i used the skydome tut to create a sphere but when i render it with GL_TRIANLGE_STRIP ogl fills the triangles white
is there a way to disable this to get the wireframe mode?


thx to invective for the create link, its very useful

To the vast majority of mankind, nothing is more agreeable than to escape the need for mental exertion... To most people, nothing is more troublesome than the effort of thinking.

This is a very cool piece of code, I adapted from the source that invective pointed to here and I am very pleased with the results, however...

How do I generate texture mapping coordinates from this calculated sphere? Any ideas...

I am using the code from source3.c as my basis. I am rendering the sphere by using GL_TRIANGLES mode and rendering as follows:

glBegin( GL_TRIANGLES );
for (i=0; i<NumFacets; i++)
glVertex3f( Facets[i].p1.x * Size, Facets[i].p1.y * Size, Facets[i].p1.z * Size );
glVertex3f( Facets[i].p2.x * Size, Facets[i].p2.y * Size, Facets[i].p2.z * Size );
glVertex3f( Facets[i].p3.x * Size, Facets[i].p3.y * Size, Facets[i].p3.z * Size );

Which appears to be correct, as the sphere shows up very nicely, but I can't seem to figure out the proper way to generate my texture mapping coordinates.
