CgFX Shader

 
 
 

Category: Realtime > CgFX

Shader Family: Realtime

Output: Realtime

Most of the CgFX shaders provided with Softimage are from the NVIDIA Shader Library. There are a wide range of shaders including skin, natural effects, metals, post processing effects, and more. The CgFX effects files are located in the Application\phenolib\cgfx folder of the Softimage installation path. You can copy and modify these effects files to build your own.

For more information about working with effects shaders in Softimage, see CgFX and HLSL Shaders [Realtime Shaders].

CgFX Shader Library

brix

Brick pattern, with controls, using texture-based patterning. The lighting is purely lambert and from a directional source, so it's done in the vertex shader. (1 technique/s).

cage

3D mesh cage effect, created by procedural texturing. Texture is pre-calculated by HLSL. Wires are aligned to world coordinates. (1 technique/s).

checker3d

3D checkerboard effect, created by procedural texturing. Texture is pre-calculated using the HLSL virtual machine. (1 technique/s).

clock

Align as a quad to screen according to the original tex coords. As a sprite, best applied to simple quads with 0-1 tex coords. Then apply "Numbers.dds" as a stream of number textures to create an apparent numeric counter driven by the vertex shader. (1 technique/s).

DebugSpaces

This effect file uses 3d checker patterns to illustrate a number of important coordinate systems and shading vectors. #define USER_COLORS if you want to use parameters instead of the fixed macro colors. (8 technique/s).

DebugValues

This effect file uses colors to illustrate a number of shading vectors. That is, values that are typically important in shading. This effect can often help find bogus parts of models, or be used to explore the contents of a model. (15 technique/s).

durer

This effect is intended to look like pen crosshatching. It was inspired by the British Museums Durer exhibit of 2003. Some of Durer's most famous drawings were made in two colors of ink on medium-colored paper. The diffuse shape rendering was drawn in cross-hatches in a dark ink. (2 technique/s).

goochy

Gooch shading with glossy highlight in HLSL ps_2 pixel shader. Textured and non-textured versions are supplied. (2 technique/s).

lambSkin

A lambertian-like surface with light "bleed-through" (appropriate for soft translucent materials like skin). The "subColor" represents the tinting acquired by light diffused below the surface. Set the "Rolloff" angle to the cosine of the angle used for additional lighting wraparound. The diffuse effect propogates based on the angle of LightDirection versus SurfaceNormal. Versions are provided for shading in pixel or vertex shaders, textured or untextured. (4 technique/s).

metal

A phong-shaded metallic surface lit from either a point or directional source. Versions are provided for textured, untextured, quadratic falloff or not. (4 technique/s).

MrWiggle

Simple sinusoidal vertex animation on a phong-shaded plastic surface. The highlight is done in vertex shading and not as a texture. Textured and Untextured versions are supplied. (2 technique/s).

plastic

A phong-shaded plastic-style surface lit from either a point or directional source. Versions are provided for textured, untextured, quadratic falloff or not. (4 technique/s).

ThinFilm

Creates the illusion that the surface is covered with a thin film of transparent material, as in oily water, thin shellacs, dirty layered ice, etc. (1 technique/s).

uvDetective

A helpful tool for artists to optimize their texture sizes, so that textures created by artists won't be too small (looks bad) or too big (wastes time on texture details that will never be seen). To use: (1) Look for regions where desired texture resolution is dominant, (2) set desired size for the "Reso" parameter, (3) and select the "TexRez" techniques. (6 technique/s).
