Gl_line
Hi,
I have gotten into reading up on graphics as abit of a hobby! Would any
anyone know if there is code available out there so i can see how to
draw a simple line in a window using the mouse. I have been reading
different tutorials, but they all stop short of this.
cheers for any replys

have you understood the OpenGL pipeline already? you will have to
project your mouse coords into the 3d space. a line can then be drawn
with the two derrived vertices.

hi,
hi, i am only currently reading up on 2D Glut programming. i have read
plenty about glutMouseFunc and things like that but i am still looking
to see if there are any good quality sites for coding examples glut &
2D programming. Rather than these API specification sites which i dont
really find too helpful.
