Streaming SIMD Streaming SIMD Streaming SIMD Streaming SIMD
An instruction set developed by Intel for Pentium III-processor based systems. Streaming SIMD can improve
3D vertice transformation and lighting, among other operations.
SVGA SVGA SVGA SVGA
Super Video Graphics Array. SVGA runs at 800 x 600.
Tessellation Tessellation Tessellation Tessellation
The initial part of the 3D pipeline where the object is described by a set of triangles.
Texture Mapping Texture Mapping Texture Mapping Texture Mapping
A technique that enables 2D graphic images to be “wrapped” around or “pasted” on to a 3D primitive.
Perspective correction and lighting calculations allow for added realism.
Transformation Transformation Transformation Transformation
The change in rotation, size, position, and perspective of an object in 3D space.
Transparency Transparency Transparency Transparency
A function that refers to the rendering of transparent (non-opaque) objects. Transparency is generally
accomplished on a polygon rendering system using either screen-door transparency or alpha blending.
Vectors/second Vectors/second Vectors/second Vectors/second
Lines drawn per second.
VGA VGA VGA VGA
Video Graphics Array. VGA runs at 640 x 480.
VHR VHR VHR VHR
Very High Resolution. VHR runs at 1280 x 1024.
VRAM VRAM VRAM VRAM
Video Random Access Memory is an expensive, fast type of RAM that is used as display memory on high-end
graphics boards.
VRML VRML VRML VRML
Virtual Reality Modeling Language.
Z-Buffer Z-Buffer Z-Buffer Z-Buffer
Also known as the Depth Buffer, the Z-Buffer is a region of memory containing the depth component of a
pixel. Used, for example, to eliminate hidden surfaces from the image.
