Setup engine
Setup engine calculates and prepares all of the parameters for
primitive drawing. All these operation, instead of making use of
CPU's loading, using 3D engine of VGA chip for 3D rendering.
Sideband Signaling
An extra 8-bits of addressing capability built into AGP, which
in effect, allows the AGP graphics board to request information
over AGP at the same time as it is receiving data over the 32-bit
datapath of the bus. This is yet another way that AGP graphics
board can create better efficiencies and improve overall
graphics performance.
Stencil Buffer
Another buffer supported by OpenGL is the stencil buffer. Like
the depth buffer, the stencil buffer can be used to eliminate
certain pixels from being drawn. The stencil buffer acts in much
the same way as a cardboard stencil used with a can of spray
paint. You can "draw" values into the stencil buffer using the
normal OpenGL rendering primitives. Then a stencil test can be
defined and stenciling enabled. This feature is particularly
useful in creating special effects such as shadowing from
multiple light source.
Stencil Test
The stencil test conditionally eliminates a pixel based on the
outcome of a comparison between the reference value and the
value in the stencil buffer.
Tessellate
To divide an object or surface into geometric primitives
(triangles, quadrilaterals or other polygons) for simplified
processing and rendering.
Texture
A two dimensional bitmap pasted onto objects or polygons, to
add realism.
Texture mapping
