What's the easiest way?

purests will howl, but have a look @ glew

Const GLU_FILL=100012 ' glu constant
Global sphereQuad:Int Ptr
sphereQuad = Int Ptr gluNewQuadric( )
gluQuadricDrawStyle( sphereQuad, GLU_FILL )
gluQuadricTexture(sphereQuad,True)
...
gluSphere( sphereQuad, obj.size[x], 16, 16 )

just ripped those fragments out of the tutorial I put on blitwiki
http://www.blitzwiki.org/index.php/OpenGL_Introduction
theres a zip of some code/textures to get you started

hope it helps
