ABSTRACT

The tools of points, lines, and planes are our most basic 3D geometry building blocks. But in order to build real objects, we must be

in to know its eight vertices. These are found by intersecting appropriate planes. A similar problem is to determine whether a given point is inside or outside the cube. This chapter outlines the basic algorithms for these types of problems. The ray traced image of Figure 11.1 was generated by using the tools developed in this chapter.1
