Geometry
The intermediate stage of the 3D pipeline, geometry determines the location of the object and the frame of
reference of the viewer in relation to the object.
Gouraud Shading
This method of shading, more complex than flat shading, shows subtle color changes across an object.
Gouraud Shading is accomplished by adding pixels in a graduated scale of colors.
Graphics Accelerator Card
A graphics accelerator performs 3D functions in the hardware, thereby relieving the CPU of repetitive,
complex and intensive calls. This results in enhanced performance and speed.
Heidi
The API developed by Autodesk to work with its products, such as 3D Studio MAX and AutoCAD.
MIP-Mapping (for texture processing)
A feature that delivers photo-realistic images by wrapping 2D bitmaps around 3D objects closely matching
the texture to the object. MIP-Mapping allows different versions of a texture to be used for objects of
different sizes. It also enables faster performance as textures do not need to be scaled in real time.
Multiple Resolution Support
The ability to support multiple resolutions on the screen.
OpenGL
The industry standard library of advanced 3D graphics functions developed by Silicon Graphics, Inc.
Perspective Correction
A function that allows an object to maintain its 3D textural features as it moves away from the viewer, into
the background.
Pipelining
A basic hardware tool for accelerating processes.
Pixel
The smallest addressable element of a cathode ray tube display. More simply put, the individual dots that
make up the screen image.
