ABSTRACT:
Methods and apparatus for perspective transforming a plurality of objects in a three-dimensional space into a two-dimensional space, each object having a plurality of vertexes, the methods and apparatus determining whether the plurality of vertexes for each of the objects are localized within the three-dimensional space; performing a first perspective transformation process on the respective plurality of vertexes of the objects when the plurality of vertexes for each of the objects are not localized within the three-dimensional space; and performing a second perspective transformation process on the respective plurality of vertexes of the objects when the plurality of vertexes for each of the objects are localized within the three-dimensional space, wherein the second perspective transformation process requires less calculating power than the first perspective transformation process.
