Constructor Details

Orientation3DEulerAngles

public Orientation3DEulerAngles(double rotationX,
 double rotationY,
 double rotationZ)

Creates a new Orientation3DEulerAngles instance.

Parameters:

rotationX - Rotation around X-dimension (in radians) anti-clockwise.

This is the alpha parameter.

rotationY - Rotation around Y-dimension (in radians) anti-clockwise.

This is the beta parameter.

rotationZ - Rotation around Z-dimension (in radians) anti-clockwise.

This is the gamma parameter.

Method Details

toString

public String toString()

Overrides:

toString in class Object

deriveRotationMatrix

protected RotationMatrix deriveRotationMatrix()

Description copied from class: Orientation

Derives a RotationMatrix that can be applied to rotate an entity anti-clockwise to the current orientation.

It presumes the existing entity has a neutral orientation along the x-axis.

Specified by:

deriveRotationMatrix in class Orientation

Returns:

the rotation-matrix.

negative

public Orientation negative()

Description copied from class: Orientation

Derives a new Orientation in the opposite (negative) direction to the current instance.

A unit step from the origin in the current orientation direction, summed with a unit step in the negative direction, should end in the origin.

Specified by:

negative in class Orientation

Returns:

the new Orientation in the negative direction.

numberDimensions

public int numberDimensions()

Description copied from class: Orientation

The dimensionality of space the orientation is valid for.

Specified by:

numberDimensions in class Orientation

Returns:

2 or 3.

equals

public boolean equals(Object o)

Specified by:

equals in class Orientation

canEqual

protected boolean canEqual(Object other)

hashCode

public int hashCode()

Specified by:

hashCode in class Orientation
