GMX User’s Guide

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.

MMX
Multi Media eXtension, a set of 57 instructions, to be added to the x86 processor,
to accelerate signal processing operations for multimedia.

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.

Point Sampling
The basic method of adding texture to an object. Point sampling does not include
any filtering of textures.
