Function Documentation

TransformF MatrixCreate	(	VectorF	position,
		AngAxisF	orientation
	)

Create a transform from the given translation and orientation.

Parameters:

	position	The translation vector for the transform.
	orientation	The axis and rotation that orients the transform.

Returns:

A transform based on the given position and orientation.

TransformF MatrixCreateFromEuler

(

Point3F

angles

)

a matrix from the given rotations.

Parameters:

Vector3F

X, Y, and Z rotation in *radians*.

Returns:

A transform based on the given orientation.

Point3F MatrixMulPoint	(	TransformF	transform,
		Point3F	point
	)

Multiply the given point by the given transform assuming that w=1.

This function will multiply the given vector such that translation with take effect.

Parameters:

	transform	A transform.
	point	A vector.

Returns:

The transformed vector.

TransformF MatrixMultiply	(	TransformF	left,
		TransformF	right
	)

Multiply the two matrices.

Parameters:

	left	First transform.
	right	Right transform.

Returns:

Concatenation of the two transforms.

VectorF MatrixMulVector	(	TransformF	transform,
		VectorF	vector
	)

Multiply the vector by the transform assuming that w=0.

This function will multiply the given vector by the given transform such that translation will not affect the vector.

Parameters:

	transform	A transform.
	vector	A vector.

Returns:

The transformed vector.
