HISTORY

Way back in 1996 in wrote the WHYz! demo in 100% assembly code for i386 on my poor old 33 MHz 486 machine. Actually, I wrote it in C first and made the assembly version from that. It was meant as an electronic birthday card. In 1997, I ported the WHYz! demo (C version) to Linux using the svgalib. In early 2006, I was playing around with SDL and ported the WHYz! demo to SDL. In 2007, I reimplemented the WHYz! demo in SDL/GL. This is a full rewrite, only the wave effect remains the same, but this was fully rewritten as well. In 2015, I greatly revised the code, and used C++.

USAGE

There are some things you can do while it is running:

• press Pause or P to pause the demo
• press w for a wireframe model (this uncovers how it all works)
• press Return to toggle fullscreen mode
• press Escape to quit the program

RANDOM REMARKS

• This was my second program with OpenGL and took 1 day to write.

• This is the first texture mapped WHYz! demo. In the other versions, I was only shoving pixels around.

• There is no music, put on your own trippy music.
