3D shaders act on 3D models or other geometry but may also access the colors and textures used to draw the model or mesh. Vertex shaders are the oldest type of 3D shader, generally making modifications on a per-vertex basis. Newer geometry shaders can generate new vertices from within the shader.
Volume shaders manipulate the color of light as it passes through a volume. They create effects such as fog. Imager shaders describe a color transformation to final pixel values. This is like an image filter, except the imager shader operates on data prior to quantization. Such data have more dynamic range and color resolution than can be ...
Shaders are written in OpenGL Shading Language and compiled. The compiled programs are executed on the GPU. The compiled programs are executed on the GPU. OpenGL Shading Language ( GLSL ) is a high-level shading language with a syntax based on the C programming language .
HLSL programs come in six forms: pixel shaders (fragment in GLSL), vertex shaders, geometry shaders, compute shaders, tessellation shaders (Hull and Domain shaders), and ray tracing shaders (Ray Generation Shaders, Intersection Shaders, Any Hit/Closest Hit/Miss Shaders). A vertex shader is executed for each vertex that is submitted by the ...
The unified shader model uses the same hardware resources for both vertex and fragment processing. In the field of 3D computer graphics, the unified shader model (known in Direct3D 10 as "Shader Model 4.0") refers to a form of shader hardware in a graphical processing unit (GPU) where all of the shader stages in the rendering pipeline (geometry, vertex, pixel, etc.) have the same capabilities.
A procedural image made in Shadertoy with distance fields, modeled, shaded, lit and rendered in realtime. Shadertoy is an online community and platform for computer graphics professionals, academics [1] and enthusiasts who share, learn and experiment with rendering techniques and procedural art through GLSL code.
HLSL shaders can enable many special effects in both 2D and 3D computer graphics. The Cg/HLSL language originally only included support for vertex shaders and pixel shaders, but other types of shaders were introduced gradually as well: DirectX 10 (Shader Model 4) and Cg 2.0 introduced geometry shaders.

Gouraud shading, developed by Henri Gouraud in 1971, was one of the first shading techniques developed for 3D computer graphics. A knot shaded with different materials including aluminum, brass, bronze, copper, electrum, gold, iron, pewter, silver, clay, foil, glaze, plastic, rubber, satin, and velvet. created in Mathematica 13.1
