c++ - mouse movement opengl -

-

i creating pool game written in c++ using plain opengl (no external tools), can use glut. have drawn pool cue want follow mouse cursor not sure how this.

i know how use keyboard input move things e.g camera position or draw object m not sure how move object using mouse input.

this cue trying move via mouse input:

void cue () {   glbegin;   gltranslatef(-10,5,0);    glrotatef(90,0,1,0);    glutsolidcone(0.25, 15, 20, 20);   glend(); }

glut has few mouse callback function
mouse callback
motion callback

you use callback figure out movement of mouse, rest pure math.
