Post by: energy on December 15, 2007

Hello to all!
I started using OpenGL this time and want to ask to share and explain some codings for Oldskool effects with OPENGL
like scrollers etc....
Jim posted some examples for copperbars, but i think only in 2D Mode...
How to use all effects mixed with 2D/3D mode?

Cheers and thanks in advance

QuoteHow to use all effects mixed with 2D/3D mode?

Just switching from orthographic mode to perspective mode and vice versa.

orthographic mode:

Code Select

	glViewport(0, 0, 800, 600);
	glMatrixMode(GL_PROJECTION);
	glLoadIdentity();
	gluOrtho2D(0.0f, 800, 600,0.0f);

perspective mode:

Code Select

	glMatrixMode(GL_PROJECTION);
	glLoadIdentity();
	gluPerspective(45.0f,800.0f/600.0f,0.1f,100.0f);
	glMatrixMode(GL_MODELVIEW);
	glLoadIdentity();
