◆ computeTranslationRotationScaleFromMatrix()

static void CesiumGeometry::Transforms::computeTranslationRotationScaleFromMatrix	(	const glm::dmat4 &	matrix,
		glm::dvec3 *	pTranslation,
		glm::dquat *	pRotation,
		glm::dvec3 *	pScale
	)

static

Decomposes a matrix into translation, rotation, and scale components. This is the reverse of createTranslationRotationScaleMatrix.

The scale may be negative (i.e. when switching from a right-handed to a left-handed system), but skew and other funny business will result in undefined behavior.

Parameters

matrix	The matrix to decompose.
pTranslation	A pointer to the vector in which to store the translation, or nullptr if the translation is not needed.
pRotation	A pointer to the quaternion in which to store the rotation, or nullptr if the rotation is not needed.
pScale	A pointer to the vector in which to store the scale, or nullptr if the scale is not needed.

◆ createTranslationRotationScaleMatrix()

static glm::dmat4 CesiumGeometry::Transforms::createTranslationRotationScaleMatrix	(	const glm::dvec3 &	translation,
		const glm::dquat &	rotation,
		const glm::dvec3 &	scale
	)

static

Creates a translation-rotation-scale matrix, equivalent to translation * rotation * scale. So if a vector is multiplied with the resulting matrix, it will be first scaled, then rotated, then translated.

Parameters

translation	The translation.
rotation	The rotation.
scale	The scale.

◆ getUpAxisTransform()

static const glm::dmat4& CesiumGeometry::Transforms::getUpAxisTransform	(	CesiumGeometry::Axis	from,
		CesiumGeometry::Axis	to
	)

static

Gets a transform that converts from one up axis to another.

Parameters

from	The up axis to convert from.
to	The up axis to convert to.

Returns: The up axis transform.
