Detailed Description

template<class T>
class Brush3T< T >

Diese Klasse implementiert Brushes.

Ein Brush ist nichts weiter als eine Ansammlung (Array) von Planes, deren Schnitt ein konvexes, dreidimensionales Polyhedron darstellt.

Eigenschaften des Brushs (Vereinbarungen):

1. Die Normalenvektoren der Ebenen müssen nach AUßEN zeigen.

Constructor & Destructor Documentation

template<class T >

Brush3T< T >::Brush3T ( )

inline

Default constructor.

template<class T >

Brush3T< T >::Brush3T	(	const BoundingBox3T< T > &	BB,
		const Vector3T< T > &	Pos
	)

Generiert einen Brush aus einer BoundingBox 'BB', die vorher nach 'Pos' verschoben wird.

template<class T >

Brush3T< T >::Brush3T	(	const Vector3T< T > &	A,
		const Vector3T< T > &	B,
		const Vector3T< T > &	C,
		const T	Epsilon,
		bool	IncludeBevelPlanes = true
	)

Creates a triangular, zero-volume brush from the vertices A, B and C.

Parameters

A	First vertice.
B	Second vertice.
C	Third vertice.
Epsilon	Tolerance value.
IncludeBevelPlanes	If false, only five planes (two for the sides and three for the edges) will be created. If true, also bevel planes will be included.

Member Function Documentation

template<class T >

void Brush3T< T >::TraceBoundingBox	(	const BoundingBox3T< T > &	BB,
		const Vector3T< T > &	Origin,
		const Vector3T< T > &	Dir,
		VB_Trace3T< T > &	Trace
	)		const

Traces the (relative) bounding box 'BB' from the (absolute) 'Origin' along 'Dir' towards the end position 'Origin+VectorScale(Dir, Trace.Fraction)'.

The result is returned in 'Trace'. This method handles the bloating and unbloating of the brush according to a description by Kekoa Proudfoot: Tracing the 'BB' against this brush is reduced to a simple ray collision test against the "bloated" brush.

Parameters

BB	Bounding box to trace.
Origin	Origin of the trace.
Dir	Direction of the trace.
Trace	Trace result.
