Question about rotation

Recommended Posts

I''m currently working on a program that will allow editing of 3d-models with the mouse. So I was wondering if someone could give advice as to how one knows how much to rotate for a line to point to whare the mouse is (hope this makes sense). The purpose of this is that one could "grab" the vertex of a line and rotate it around the line''s other vertex. I''m not too sure about rotation-matrices and things, so I really don''t know how to do this. Also, the program needs to do it with glRotatef. So no just moving the point. I need to know in what way and how much to glRotatef. Any help is welcome and duly thanked in advance.
