- Demo programs in this directory:
-
- vgatest
-
- Mode test program.
-
- fun
-
- Random moving pixels accumulate in clusters. Uses virtual screens
- for frame animation.
-
- mousetest
-
- Simple program to test mouse functionality. Left button changes
- color, right button exits.
-
- keytest
-
- Similar program to test low-level keyboard interface.
-
- scrolltest
-
- Smooth scrolling demo. Uses three different techniques. Useful for
- testing Mode X functionality (not that I would recommend it over
- 320x200x256 linear).
-
- speedtest
-
- Video memory speed tester.
-
- testgl
-
- Demo program for vgagl framebuffer library.
-
- testlinear
-
- Program to test linear addressing on Cirrus cards (and on Mach32).
-
- testaccel
-
- Program to test the old blit functions in a screen mode. Checks
- the 8-bit wide color lookup tables on Mach32's with type 2 DACs
- as well. [I think '6bpp' and '8bpp' are silly names for the 8-bit
- LUT thing -- bpp is bits per pixel, in the framebuffer - HH :-)]
-
- accel
-
- Test new-style accelerated functions.

- You're encouraged to send in more data (send to hhanemaa@cs.ruu.nl).
-
- There's also a 3D demo binary included in this directory. It has been in a
- similar state for several months now, but I'm planning to get some work
- done (although it probably won't be the amazing multi-player networked
- 3D lightsource-shaded real-time VGA virtual reality simulation). I'll
- release the source code at some point (when it has some degree of
- flexibility). I'm sorry that there's no scene description file; it will
- come. So now you know you can do this kind of thing in Linux. And it's
- practically 100% C code.
-
- You can set the graphics mode to be used with the GSVGAMODE environment
- variable (e.g. G640x480x256). All linear 256 color, 32K color and 16M color
- modes are supported, with page flipping used if available. Planar 256 color
- VGA modes also work. This should do 800x600 full screen 3D animation at near
- 10 fps with a good system.
-
- Request: Please report if page flipping goes wrong on a particular chipset
- (e.g. ET4000, Trident) in 320x200x256. Also 32-bit pixel truecolor
- modes don't work correctly, this will be fixed.
-
- The user interface is somewhat primitive at this point:
-
- - Use the mouse to rotate.
-
- - Left button accelerates, right decelerates.
-
- - Press w to move upwards, s to go down again.
-
- - Use r and f to control the zoom factor.
-
- Note that the light source rotates quickly at an infinite distance. This
- is not something that will easily occur naturally (as far as I know)...
