More personal research on attempting to implement high-end effects on low-end hardware. This example describes a way to perform simple self-occluded shadowing on tangent space normal maps on PS.1.1 and Xbox, with the use of an 8-bit height/occlusion map (stored in an alpha channel of a texture).

This is the result of some personal research I had done at Matrox with vertex shaders. Curvilinear Projection 'curves' the on-screen geometry so that the field of vision is not as restrictive as it is in linear projection, also correcting the geometric aspect ratios across the rendering field. This is done at the low cost of a single transform per vertex through a vertex shader (as opposed to multiple transforms for multiple render targets). This method was developed, designed and implemented by yours truly.

)

)
Being their lead technical artist, the Matrox Graphics R&D team had approached me with the task of creating displacement mapped geometric content, to test the efficiency and development flow of the new technology. This required close work with the engineers for bug-stomping, as well as pushing for additional features. I also had to convince the Microsoft DirectX team that displaced characters were possible with careful UV mapping and texturing crafting. * All content is the legal property of Matrox Graphics, Inc. and is no longer supported by the company. :::: "Frustos" Sidescroller 3DFX Glide Engine :::: )
)

)
)
This was a mini-3D-SideScroller game engine I had programmed back in 1998 for research during my days at Ubi Soft. It used 3DFX's Glide API for rendering the geometry. File loaders, parsers, texture memory management, voxel-based frustum culling, moving dynamic ranged lighting, etc. were all programmed ("from scratch") by myself in Ansi C. |
