I am trying to write a program which allows users to create a 3d wireframe. Users will be allowed to model the wireframe by drwaing lines in a 3d space. But my 3d graphics knowledge is very bad.
Can you please suggest me any online documents on this subject which will help me to do this program. Can you also tell me wether there are things I have to do to check the wireframe modelled by user is a valid wireframe.
