Detailed Description

template<typename T = double>
class geom::ScanConversionPolyhedron< T >

A class for a polyhedron in 3-D designed for scan conversion.

Parameters:

T

is the number type. By default it is double.

As the name suggests, this class is designed for 3-D polyhedron scan conversion. The Polyhedron is represented as a set of edges. The edges support mathematical operations that enable efficient slicing to obtain polygons. This, in turn, enables efficient scan conversion.

	)			const

Scan convert the polyhedron.

Parameters:

	coordinates	is an output iterator for the set of coordinates inside.
	grid	describes the grid on which to perform the scan conversion.
