modeling concepts ?– 109
The more polygons you have in a model, the more detailed it becomes. However,
greater numbers of polygons tax your system and take longer to render. This is where the
term low-poly modeling originates. In computer or console games, the machine renders
the scene on the fly, so its computation requirements are strict. The fewer the polygons
in the scene, the faster the game can play back. Games frequently use low-poly models to
maximize the effect in their game without sacrificing precious computational cycles.
Higher-resolution models are typically used in television and film, because the scenes
are all rendered beforehand and then laid off to video tape or output to film. A computational
ceiling is still dictated by the machines that are used in creating the TV or film animations,
however, so it is always a good idea to be smart when creating models.
Primitives
Primitives are the basic 3D geometric shapes that are automatically generated by 3D modeling
applications. As such, they do not need to be constructed from scratch. A considerable
amount of modeling (perhaps most) begins with primitives, which are then edited and
used with other primitives to create more complex objects.
