buffering to deliver smooth animation): one is being calculated
by the 3D accelerator while the other one is being send to the
monitor.
Frame Rate
The number of Frames per second (FPS) is the unit of measure
in an animation that is used to describe graphics and video. In
general, an animation with a higher frame rate plays more
smoothly than with a lower frame rate, but takes longer to
render.
Gouraud Shading
Gouraud shading is a complex process using algorithms to
create a color gradient Gouraud shading is a method in which
the triangle color is obtained by interpolating the vertex colors
that are located at each corner of the triangle. By utilizing this
technique, 3D objects appear increasingly realistic due to the
smooth, curved appearance of the surfaces, even though they
consist of many separate polygons.
Interlacing
A display technique that enables a monitor to provide more
resolution inexpensively. With interlacing monitors, the
electron guns draw only half the horizontal lines with each
pass (for example, all odd lines on one pass and all even lines
on the next pass). Because an interlacing monitor refreshes
only half the lines at one time, it can display twice as many
lines per refresh cycle, giving it greater resolution. Another
way of looking at it is that interlacing provides the same
resolution as non-interlacing, but less expensively. A
shortcoming of interlacing is that the reaction time is slower, so
programs that depend on quick refresh rates (animation and
video, for example), may experience flickering or streaking.
Given two display systems that offer the same resolution, the
non-interlacing one will generally be better.
LOD
Level of Detail (LOD) or MIP - levels is used to describe the
quality of the texture map used.
