NAME

scrolltest - tests some scrolling algorithms with svgalib

SYNOPSIS

scrolltest

DESCRIPTION

Smooth scrolling demo. Uses three different techniques. Useful fortesting Mode X functionality (not that I would recommend it over320x240x256 linear). Press<Space>to cycle through the demos.

The demos works only in 320x240x256 for the first 2 testsand with 320x200x256 in the last. Demos 1 & 3 use a virtual screenbuffer, mode 2 (jumpy) works on screen. This is more a skeleton ifyou want to write some animation program, rather than a nice demo.

Shows frames per second (multiplied by 10) for method 1 & 3. Thusworks also a kind of memory speed tester

This demo is part of svgalib and can be found in thedemos/subdirectory of the original svgalib distribution. However, it is not installed in the systemby default, s.t. it is unclear where you can find it if your svgalib was installed by somelinux distribution. Even then, when you have the demo on your system, you probably won't havethe sources s.t. it is only of limited use for you.

In case of any such problem, simply get an svgalib distribution from the net. You evendon't need to install it. Justmakein thedemos/subdirecty. As of this writing,svgalib-1.2.12.tar.gzis the latest version and can be retrieved by ftp fromsunsite.unc.edu at /pub/Linux/libs/graphicsandtsx-11.mit.edu at /pub/linux/sources/libswhich will most probably be mirrored by a site close to you.
