Glossary
Alpha-Blending - Technique for add-
ing transparency information for trans-
lucent objects.
Alpha Buffer - An extra channel to
hold transparency information; pixels
become quad values (RGBA).
Anti-Aliasing - Subpixel interpola-
tion, which makes the edges appear to
have better resolution.
Atmospheric Effect - The result of
adding one more layer of reality, such
as fog and depth cueing, to an image.
Bi-linear Filtering - A method of anti-
aliasing texture maps that averages
four adjacent pixels.
Bi-linear MIP Mapping - A texture-
mapping process combining bi-linear
filtering and MIP mapping.
Blending - Combining two or more
images by adding them on a pixel-by-
pixel basis.
Decal Texturing - The process of ap-
plying a texture to a surface without
lighting.
Depth Cueing - The lowering of in-
tensity as objects move away from the
viewpoint.
Direct3D
- Microsoft's low-level
primitive-based 3D API. It includes
optional control for low-level trans-
formations, lighting and rasterization.
Dithering - A technique for achiev-
ing 24-bit quality in 8-bit or 16-bit
frame buffers.
Double Buffering - A method of us-
ing two buffers, one for display and
the other for rendering. When the
new frame is rendered, the two buff-
ers are switched.
Fog
- Blending an object with a fixed
color as its pixels increase in distance
away from the viewer.
Gouraud Shading - Rendering a
polygon through linear interpolation
using a specified color at each vertex.
MIP Mapping - A method of increas-
ing the quality of a texture map by ap-
plying different-resolution texture
maps for different objects in the same
image, depending on their size and
depth.
Perspective Correction - The process
of adding realistic convergence to
three-dimensional objects as they
move away from the viewpoint.
Point-Sampled Texture Mapping -
Texture mapping based on a one-to-
one relationship between texels on a
rendered polygon and a texture map.
Rasterization - Translating an image
into pixels.
Rendering - The stage of the 3D pipe-
line that creates a 2D display from a
set of 3D polygons fed from the ge-
ometry engine.
