MatrixCreate()

String MatrixCreate	(	posVec	,
		rotVec	)

Use the matrixCreate function to create a transform matrix from a three-element floating-point translation vector and a four-element floating-point rotation vector.

Parameters

posVec	A three-element floating-point translation vector: \PosX PosY PosZ.
rotVec	A four-element floating-point rotation vector: \RotX RotY RotZ.
These	re rotations about the specified axes.

Returns

Returns a transform matrix of the form \PosX PosY PosZ RotX RotY RotZ theta.
