Title:

    Hardware-assisted CSG rendering

Presenter(s)/Author(s):



Abstract:


    One of the most intuitive ways to model solid objects is by constructing them hierarchically, through combinations of simpler objects. Several representations that incorporate this paradigm exist, of which CSG is the most popular. In the CSG representation, solid objects are obtained by successive boolean combinations of primitives, and are represented by  the expression corresponding to the sequence of boolean op- erations of primitives that led to them. These CSG expres- sions are stored as trees called CSG trees, whose leaves rep- resent primitives and nodes represent boolean operations.
