UT_API UT_Vector4 colVecMult	(	const UT_DMatrix4 &	m,
		const UT_Vector4 &	v
	)

Multiplication of a row or column vector by a matrix (ie. right vs. left multiplication respectively). The operator*() declared above is an alias for rowVecMult().

UT_API UT_Vector4 colVecMult	(	const UT_Matrix4 &	m,
		const UT_Vector4 &	v
	)

Multiplication of a row or column vector by a matrix (ie. right vs. left multiplication respectively). The operator*() declared above is an alias for rowVecMult().

UT_API UT_Vector4 colVecMult3	(	const UT_DMatrix4 &	m,
		const UT_Vector4 &	v
	)

Multiplication of a row or column vector by a matrix (ie. right vs. left multiplication respectively). The operator*() declared above is an alias for rowVecMult().

UT_API UT_Vector4 colVecMult3	(	const UT_Matrix4 &	m,
		const UT_Vector4 &	v
	)

Multiplication of a row or column vector by a matrix (ie. right vs. left multiplication respectively). The operator*() declared above is an alias for rowVecMult().

UT_API UT_Vector3 cross	(	const UT_Vector4 &	v1,
		const UT_Vector4 &	v2
	)

Although the cross product is undefined for 4D vectors, we believe it's useful in practice to define a function that takes two 4D vectors and computes the cross-product of their first 3 components
