Function Documentation

PXR_NAMESPACE_OPEN_SCOPE GF_API GfVec4f GfGetHomogenized

(

const GfVec4f &

v

)

Returns a vector which is v homogenized. If the fourth element of v is 0, it is set to 1.

GF_API GfVec4d GfGetHomogenized

(

const GfVec4d &

v

)

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.

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.

GfVec3f GfProject ( const GfVec4f &  v )

inline

Projects homogeneous v into Euclidean space and returns the result as a Vec3f.

Definition at line 65 of file homogeneous.h.

GfVec3d GfProject ( const GfVec4d &  v )

inline

Projects homogeneous v into Euclidean space and returns the result as a Vec3d.

Definition at line 72 of file homogeneous.h.
