Thread: Generating an icosphere

Does anyone have any links for this? I used to but every time I google this I get stupid Photoshop, Blender, GIMP, or other tutorials for other apps that I could care less about.

I know I can start with a geometric primitive like a tetrahedron, dodecahedron, cube, etc, and recursively split it to arrive at my sphere but I forget exactly how to do that.

Code:

void CIcoSphere::Split(Vertex &Result,Vertex v1,Vertex v2,Vertex v3)
{
  D3DXVECTOR3 vec1=v1.Pos-v2.Pos;
  D3DXVECTOR3 vec2=v1.Pos-v3.Pos;

  D3DXVec3Lerp(&Result.Pos,&vec1,&vec2,0.5f);

  D3DXVECTOR2 vecU=v1.TexCoord1-v2.TexCoord1;
  D3DXVECTOR2 vecV=v1.TexCoord1-v3.TexCoord1;

  D3DXVec3Lerp(&Result.TexCoord1,&vecU,&vecV,0.5f);
}

Something like that maybe?

I'm abandoning UV spheres in my game engine because texturing them is far too problematic.
