- to compile programs in the above-indicated sub- directories/trees,
- one must load libglut. inst-able images of GLUT v3.1 are located at

-
- A collection of programs that exercise some of the
- GL extensions introduced in IRIX 5.3 and IRIX 6.2. These
- examples run on only a subset of SGI platforms.
- All of these programs 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 5.3), but because these
- programs use extensions to the OpenGL standard, they will
- not run properly on releases that do not support these extensions.
- IRIX 5.3 or later is recommended.

-
- fog_func.c
- This program demonstrates using the fog_func extension to
- define a fog blending function.
-
- Escape key - exit the program
- <f> key - change the fog blend function
- UP Arrow Key - increase the fog density or end value
- DOWN Arrow Key - decrease the fog density or end value
-
-
- fog_offset.c
- This program demonstrates using fog offset to make a fogged
- object appear brighter.
-
- Escape key - exit the program
- <o> key - toggle fog offset
- <f> key - change the fog blend function
- UP Arrow Key - increase the fog density or end value
- DOWN Arrow Key - decrease the fog density or end value
-
-
- interlace.c
- This program demonstrates GL_SGIX_interlace.
-
- <i> key - toggle interlacing on/off
- LEFT Arrow Key - increase the X zoom value
- RIGHT Arrow Key - decrease the X zoom value
- UP Arrow Key - increase the Y zoom value
- DOWN Arrow Key - decrease the Y zoom value
- Escape key - exit the program
-
-
- multisample.c
- Uses the GL_SGIS_multisample extension to antialias a parametric grid
- on a nurb surface.
-
- Left Mousebutton - move eye position
- Middle Mousebutton - change twist angle
- Right Mousebutton - move up / down to zoom in / out
- Escape Key - exit the program
- m Key - toggle multisampling on / off
- p Key - toggle polygon offset on / off
- R Key - reset view
-
-
- point_parameters.c
- This program demonstrates GL_SGIS_point_parameters. It
- allows you to change various point attributes dynamically.
-
- <a/A> key - increase/decrease the 'a' coefficient
- <b/B> key - increase/decrease the 'b' coefficient
- <c/C> key - increase/decrease the 'c' coefficient
- <f/F> key - increase/decrease the fade threshold size
- <m/M> key - increase/decrease the minimum point size
- <x/X> key - increase/decrease the maximum point size
- Escape key - exit the program
-
-
- sharpen_texutre.c
- Uses the GL_SGIS_sharpen_texture extension to sharpen the edges
- of a simple texture image.
-
- Escape key - exit the program
- <s> key - cycle through sharpen filters
-
-
- sprite.c
- This program demonstrates GL_SGIX_sprite.
-
- <i> key - toggle xxxx on/off
- Escape key - exit the program
