hi guys i need your help
i got a simple problem...
i got a 3d model displayed...
now want i want is, clicking on the model with the mouse and getting the coordinates of the nearest vertex to the mouse pointer.
in other words i need a selection-vertex function which is included in every 3d modelling pogramm.
i know i have to caculate from 2d mouse coords to 3d model coords.. but i dont know how?!?!
have you got any tutorials on this ??
or can you write me the basics?
p.s. i cannot use any glut functions only opengl!
glut is not allowed in my c++ code (dont ask why )
