Cg programs are built for different shader profiles that stand for GPUs with different capabilities. [8] These profiles decide, among others, how many instructions can be in each shader, how many registers are available, and what kind of resources a shader can use.
The first shader-capable GPUs only supported pixel shading, but vertex shaders were quickly introduced once developers realized the power of shaders. The first video card with a programmable pixel shader was the Nvidia GeForce 3 (NV20), released in 2001. [ 3 ]
Much of this work was done at the Cornell University Program of Computer Graphics; a 1997 paper from that lab [1] describes the work done at Cornell in this area to that point. "Physically Based Shading" was introduced by Yoshiharu Gotanda during the course Physically-Based Shading Models in Film and Game Production at the SIGGRAPH 2010.
Other functions like abs, sin, pow, etc, are provided but they can also all operate on vector quantities, i.e. pow(vec3(1.5, 2.0, 2.5), abs(vec3(0.1, -0.2, 0.3))). GLSL supports function overloading (for both built-in functions and operators, and user-defined functions), so there might be multiple function definitions with the same name, having ...
The shader assembly language in Direct3D 8 and 9 is the main programming language for vertex and pixel shaders in Shader Model 1.0/1.1, 2.0, and 3.0. It is a direct representation of the intermediate shader bytecode which is passed to the graphics driver for execution.
Version 1.00 was released in January 1995, [13] with the primary author being the company co-owner and software developer Ton Roosendaal. The name Blender was inspired by a song by the Swiss electronic band Yello , from the album Baby , which NeoGeo used in its showreel .
IRIS Inventor 1.0 (1992) was released by SGI, which was a high level scene graph built on top of Performer. It was followed up with Open Inventor in 1994, another iteration of the high level scene graph built on top of newer releases of Performer. More 3D scene graph libraries can be found in Category:3D scenegraph APIs.
