README file from "glx_extensions" directory
~opengl2/examples/glx_extensions README Copyright 1994, Silicon Graphics, Inc. Technical Education Development All Rights Reserved. A collection of programs that exercise some of the GLX introduced since IRIX 5.3. All of these programs (should!) check if the extension exists before trying it. NOTE: These programs have been #ifdef'ed so that they will compile on older release (prior to IRIX 6.2), but because these programs use extensions to the OpenGL standard, they will not run properly on releases that do not support these extensions. visual_info.c Demonstrates how the GLX_SGI_visual_info extension can be used to create an overlay window with a transparent pixel. SPACE bar - toggle animation on/off Escape key - exit the program make_current_read.c Demonstrates how the GLX_SGI_make_current_read extension can be used to copy from one window to another. <c> key - copy from read window to write window Escape key - exit the program swap_control.c Demonstrates how the GLX_SGI_swap_control extension can be used to regulate how often the color buffers are swapped. Escape key - exit the program Up Arrow - increment swap interval Down Arrow - decrement swap interval video_sync.c Demonstrates how to use the GLX_SGI_video_sync extension to synchronize with the video frame rate of a monitor. Escape key - exit the program Up Arrow - increment wait interval Down Arrow - decrement wait interval Right Arrow - increment modulus Left Arrow - decrement modulus
