angle

Angle angle()

Gets the the rotation in degrees always in clockwise order.

Returns:

The rotation

toRotationMatrix

default Matrix4d toRotationMatrix()

Gets the 4D rotation matrix of this rotation.

Minecraft's coordinate system is different than traditional systems applying the semantic meaning behind the x and z axis. These natures are described as below:

• The x-axis indicates the east (when positive) or west (when negative) of the origin point (0, 0, 0)
• The z-axis indicates the south (when positive) or north (when negative) of the origin point (0, 0, 0)

These rules differ from traditional coordinate interpretations and therefore may be unintuitive when a rotation of 90 degrees will instead rotate the coordinates (1, 1, 1) across the pivot (0, 0, 0)

Returns:

The euler matrix that represents this rotation in the X-Z plane.
