c++ - gluLookAt in reshape function -


this how reshape func looks like

`void reshape(int w, int h) {      const float ar = (float)w/(float)h;      glviewport(0,0,w,h);      glmatrixmode(gl_projection);      glloadidentity();                    gluperspective(20.0, ar, 1.0, 60.0); // fovy, aspect ratio, znear, zfar      glmatrixmode(gl_modelview);       glloadidentity();                glulookat(7,7,7,0,-1,0,0,1,0); }`

when rotate view , resize window camera comes position set in glulookat. should change, when want camera stay in rotated place after resize?

i bet have glu @ in display. are. wiping in next frame after reshape.

anyway better saving window size in int w, h; , have glulookat in display or update func. or infact can leave viewport call there.

i recommend looking @ glfw rather glut when fixed.
