I am doing a project with c# ,but since I am very new on learning c# I have lots of problems.In my project I am required to create 3 dimensional shape (shape of a molecule,i.e. 3 sphere connected each other with cylinders).And then I must translate and rotate the shape with mouse control or button control.But I don't know how to control the shape.I think I can do it with user control but I don't know how? Can anybody help me? Thank you...
