Detailed Description

A 3D polygon.

A Poly object either stores a triangle or a quad. The polygon is defined by a list of indices in an object's vertex list.

Member Function Documentation

bool Frz::Object3d::Poly::operator==

(

const Poly &

p

)

[inline]

Compares two polygons.

All possible rotations are tested for equality comparison.

Returns:

true if the polygons are equal, false otherwise

void Frz::Object3d::Poly::read

(

std::istream &

in

)

[inline]

Reads a polygon from an input stream.

Parameters:

in

a reference to the input stream

void Frz::Object3d::Poly::write

(

std::ostream &

out

)

[inline]

Writes a polygon into an output stream.

Parameters:

out

a reference to the output stream

Friends And Related Function Documentation

std::ostream& operator<<	(	std::ostream &	out,
		const Poly &	q
	)			[friend]

Displays a polygon in human-readable fashion.

Parameters:

	out	a reference to the output stream
	q	a reference to the polygon to be displayed

Returns:

a reference to the output stream
