Model Requirement
Modeling for games
Typical game requirements for models are:
* Models
must have
low polygon count;
Each poly/triangle is a thing that needs to be drawn and although average modern
video card can
draw a million triangles, it should be divided among all of
objects on screen, plus
shaders eat a lot of GPU's time.
* Models
should use only 1 texture map (additionally
normal map,
specular map and
opacity map; the last one is rarely used);
* Maps (texture/normal/etc...)
should be
power-of-two.
