I am developing OpenGL program of Win32 Console Application using VC++6.0. Is there an easy way to prevent my image being stretched (instead, just make it bigger) each time I resize my window? What is the functions associated? Thanks for any help. Edited by - cwchan on November 1, 2001 3:08:25 PM

This should be on the OpenGL forum, but glOrtho or glFrustum in combination with glViewport. Specifically the height and width need to be the same ratios in both glOrtho/glFrustum and glViewport. I suggest setting up a test program to play with the numbers and see what happens.
