None else than the 90ies 'dream team' of computer graphics, John Carmack and Michael Abrash, rolled up the sleeves and put all of their expertise, into this colossus of, now legacy, 3D game technology. While Doom had as its core technical novum(from an implementation perspective) a few assembly procedures plus mainly C code rubbing itself somewhat close to the 486s strengths, Quake made far more serious effort to designate the emerging 586 as its ultimate platform. This NeXT iteration of awe did not only excel at the conceptual technical level but also in the way it was implemented on 'contemporary machinery' - the Pentium. In early 1996, when id software was still king of the hill, most of the PC Scene was seething with anticipation of what 'the next big thing' would be. Only a few select offerings by gifted individuals can lastingly influence whole genres, or even create new ones, and Quake, alongside Doom, was perfectly matching multiple tough criteria in their relevant 'eon' - render-ing them timeless classics.

You're going to need the artwork/content from the game because it is not redistributable.Quake represented a paradigm shifter in multiple aspects. To test this modified engine just place the binary in your game's folder to frag all day long!Įnsure you have a copy of Quake 3 Arena installed on your PC. 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. To produce the cell shading effect there is no use of graphics card shaders, so the implementation can run with almost any gfx card.

To increase the hand-painted effect they decided to apply a simple blur filter to reduce hard-edges on textures and increase the flatness effect. It uses four subquadrants to calculate the mean and variance and chooses the mean value for the region with the smallest variance. Kuwahara filter is a noise-reduction filter that preserves edges.

In order to provide such a feature the production team have decided to use Kuwahara filter. The goal of this project is to add Cell Shading capabilities to the Quake III engine with Real-time performance.
