Member Function Documentation

static void TransformMatrix::setIdentity

(

TTransformMatrix

dest

)

[static]

Reset transformation to identity.

static void TransformMatrix::copyMatrix	(	TTransformMatrix	dest,
		TTransformMatrix	src
	)			[static]

Copy internal matrix.

Parameters:

	dest	Destination matrix.
	src	Source matrix.

static void TransformMatrix::mulMatrix	(	TTransformMatrix	dest,
		TTransformMatrix	a,
		TTransformMatrix	b
	)			[static]

Matrix multiplication.

Parameters:

	dest	Destination matrix (will be overwriten).
	a	Matrix a.
	b	Matrix b.

void TransformMatrix::rotate	(	float	angle,
		SpatialVector	vect
	)

Transformation: rotation.

Parameters:

	angle	Angle of rotation.
	vect	Spatial vector to rotate around.

Attention:

Behavior of vect parameter is messy and was not tested on non-trivial inputs.

Parameters:

vect

Scale vector.

void TransformMatrix::shear

(

SpatialVector

)

This method is not implemented.

Todo:

Implement

Vertex TransformMatrix::transform

(

Vertex

vertex

)

Parameters:

vertex

Original vertex.

Returns:

Return transformed vertex.
