Graphics3D

Graphics3D width, height, depth, mode, rate

Initialise the library; this command will set horizontal and vertical resolution with width and height. Other parameters (depth, mode, rate) are optional, and currently unused.

ATTENTION: this command does not create an openGL context (that is, a place where the 3d image is rendered: it can be the full screen, a window, or a place inside a window); you'll need to create it manually: in FreeBasic, the simplest way to do that is with SCREEN command:

SCREEN 18, 32, , &h02

Graphics3d 640,480,32,1,1

(the &h02 parameter in SCREEN command specify to use openGL); of course, SCREENRES, too, can be used:

SCREENRES 640, 480, 32, , &h02  
Graphics3d 640,480,32,1,1

Otherwise, external libraries like GluT can be used, or system-specific APIs can be called.
