tz::trs Struct Reference

Description

Encapsulates a combination of a Translation, Rotation, and Scale in 3D space.

#include "trs.hpp"

Public Member Functions
trs	lerp (const trs &rhs, float factor) const
	Linearly interpolate between this transform and another based on a factor, and return that result.
m4f	matrix () const
	Create a matrix that performs an identical transformation.
trs	inverse () const
	Return an inverse transform that does the exact opposite (such that multiplying a transform by its inverse yields no transformation).
trs	combine (const trs &rhs)
	Combine one transform with another, and return the result.

Static Public Member Functions
static trs	from_matrix (m4f mat)
	Create a new TRS that performs the identical transformation to the given matrix.

Public Attributes

	Rotation Component.
tz::v3f	scale = tz::v3f::filled(1.0f)

lerp()

trs tz::trs::lerp	(	const trs &	rhs,
		float	factor ) const

Linearly interpolate between this transform and another based on a factor, and return that result.

matrix()

m4f tz::trs::matrix

(

)

const

Create a matrix that performs an identical transformation.

from_matrix()

static trs tz::trs::from_matrix ( m4f mat )

static

Create a new TRS that performs the identical transformation to the given matrix.

inverse()

trs tz::trs::inverse

(

)

const

Return an inverse transform that does the exact opposite (such that multiplying a transform by its inverse yields no transformation).

combine()

trs tz::trs::combine

(

const trs &

rhs

)

Combine one transform with another, and return the result.

Note

TRS combine operations, like matrix multiplications, are not commutative.
