Bitmap font problem in fullscreen and when resizing screen

OpenGL OpenGL: Basic Coding

Hi,

Another problem.

I have used code similar to that in NeHe’s tutorial for bitmap fonts.

The problem is when I run fullscreen the text becomes garbled and the program hangs.
When I resize the screen at certain screen ratios the text disapears?

anybody know whats going on

I’m not sure about the fullscreen problem offhand, but the resizing problem might be becuase you are not properly resetting the projection matrix. I usually do something like this in my resize function…

glViewport(0,0,width,height);
glMatrixMode(GL_PROJECTION);
// Don’t forget to reset the matrix or
// subsequent calls to glFrustum/glOrtho
// will be multiplied by the previous
// projection matrix.
glLoadIdentity();
glFrustum(left,right,top,bottom,front,back);
glMatrixMode(GL_MODELVIEW);
