Class R2TransformSiOT

java.lang.Object

com.io7m.r2.core.R2TransformSiOT

All Implemented Interfaces:

R2TransformNonOrthogonalReadableType, R2TransformReadableType, R2TransformType

public final class R2TransformSiOT
extends Object
implements R2TransformNonOrthogonalReadableType, R2TransformType

A transform represented by a scale, followed by an orientation, followed by a translation.

The transform allows independent scaling on each axis and may therefore produce matrices that are not orthogonal.

Construct a transform using the given initial values. The given vectors are not copied; any modifications made to them will be reflected in the transform.

Parameters:

in_orientation - The orientation

in_scale - The scale

in_translation - The translation

Returns:

A new transform

newTransform

public static R2TransformSiOT newTransform()

Construct a transform using the default values: The identity quaternion (0, 0, 0, 1) for orientation, the scale vector (1, 1, 1), and the translation (0, 0, 0).

Returns:

A new transform

getOrientation

public com.io7m.jtensors.Quaternion4FType getOrientation()

Returns:

A quaternion representing the current orientation

getScale

public com.io7m.jtensors.Vector3FType getScale()

Returns:

A vector representing scale in three dimensions

getTranslation

public com.io7m.jtensors.parameterized.PVector3FType<R2SpaceWorldType> getTranslation()

Returns:

A translation in world-space

transformMakeMatrix4x4F

public void transformMakeMatrix4x4F(R2TransformContextType context,
                                    com.io7m.jtensors.parameterized.PMatrixWritable4x4FType<R2SpaceObjectType,R2SpaceWorldType> m)

Description copied from interface: R2TransformReadableType
