GfGetHomogenized()

GF_API GfVec4f GfGetHomogenized

(

const GfVec4f &

v

)

GF_API GfVec4d GfHomogeneousCross	(	const GfVec4d &	a,
		const GfVec4d &	b
	)

Homogenizes a and b and then performs the cross product on the first three elements of each.

Returns the cross product as a homogenized vector.

GfHomogeneousCross() [2/2]

GF_API GfVec4f GfHomogeneousCross	(	const GfVec4f &	a,
		const GfVec4f &	b
	)

Homogenizes a and b and then performs the cross product on the first three elements of each.

Returns the cross product as a homogenized vector.
