Clipped view of projection

My ReshapeFunc function looks like this - but it isn't working well
[Edited by - versus5 on November 11, 2009 7:52:47 PM]
void reshape(int w,int h){ GLfloat aspectRatio; if(h==0) h=1; glMatrixMode(GL_PROJECTION); glLoadIdentity(); glViewport (0, 100, (GLsizei) w, (GLsizei) h); gluOrtho2D(0, 800, 0, 500 ); //small clipped view //--this part is not working> glLoadIdentity(); glViewport (0, 0, 100, 100); gluOrtho2D(0, 800, 0, 500 ); //--this part is not working < glFlush();}[Edited by - versus5 on November 11, 2009 7:52:47 PM]
You're passing a width value of 0 into glViewport, that's probably not what you want.
Also, why are you setting the viewport/ortho matrix, and then immediately overwriting those settings?

The whole code
Sure, my mistake, but after changing width into e.g. 100 the big image doesn't apearing in previous viewport. It shows only the small view.
