Hi, I wonder if anyone can give me some pointers? I''m trying to project the edges of a defined shape (in this case a cube) onto the surface of a unit sphere. I can derive the corner vertices coordinates for those (corner) points on the sphere but I am unsure how to draw the edges, do I have to use bezier patches or nurbs? (and I haven''t got a clue how to use them!) Many thanks, Ben....

Project a cube onto a sphere? What does that mean? Have the sphere inside the cube and pull the cube in so that it fits onto the sphere? Or take the cube and flatten it into a 2d object then wrap it around the sphere? ... Take the edges of the cube and just draw lines onto the sphere??

Maybe a little clearer picture is needed...

S.
