engine with Real-time performance.

In order to provide such feature we have decided to use Kuwahara filter.
Kuwahara filter is a noise-reduction filter that preserves edges.

It uses four subquadrants to calculate the mean and variance and chooses the
mean value for the region with the smallest variance.

To increase the hand-painted effect we have decided to apply a simple blur
filter to reduce hard-edges on textures and increase the flatness effect.

To produce the cell shading effect we use no graphics card shaders, so our
implementation could run with almost any gfx card. The edge effect is produced
by painting backface polygons with a thick wireframe without textures and
repaint all the scene, but this time, with textures.

We have also implemented a different algorithm (we call it White Texture),
which uses white textures. It looks like this and this, you can set the
console variable r_celshadalgo to 2, and load another map, or run using the
appropiate link that came with the release.

Quake III Arena, developed by the gaming wizards at id Software,
is the third installment of one of the most popular computer game
franchises of all time. Organic caverns, gothic cathedrals and
futuristic spacescapes play host to Quake III Arena's unrivaled
blend of action, strategy and jaw-dropping technology as Linux
gamers are invited to square off against 32 of history's greatest
warriors. Built around a revolutionary new graphics engine capable
of delivering mind blowing 3D special effects including curved
surfaces and volumetric fog, Quake III Arena is the final word in
deathmatching mayhem.
The goal of this project is to add Cell Shading capabilities to the Quake III
engine with Real-time performance.
This is a native build for FreeBSD. Sorry, no joystick support
is available at this time.
In order to provide such feature we have decided to use Kuwahara filter.
Kuwahara filter is a noise-reduction filter that preserves edges.
