+ Three.js uses <em>intrinsic</em> (Tait-Bryan) ordering, also known as <em>yaw</em>, <em>pitch</em>
|
|
|
|
|
+ and <em>roll</em>. This means that rotations are performed with respect to the <em>local</em>
|
|
|
|
|
+ coordinate system. That is, for order 'XYZ', the rotation is first around world-X, then around
|
|
|
|
|
+ local-Y (which may now be different from the world Y-axis), then local-Z (which may be different
|
|
|
|
|
+ from the world Z-axis).<br /><br />
|
|
|
|
|
+
|
|
|
|
|
+ Some implementations may use <em>extrinsic</em> (proper) ordering, in which case rotations are performed
|
|
|
|
|
+ with respect to the <em>world</em> coordinate system, so that for order 'XYZ', the rotations
|
|
|
|
|
+ are around world-X, world-Y, and world-Z.<br /><br />
|
|
|
|
|
+
|
|
|
|
|
+ Converting between the two types is relatively straightforward, you just need to reverse the order
|
|
|
|
|
+ and the rotation, so that an intrinsic (three.js) Euler rotation of angles a, b, c about XYZ
|
|
|
|
|
+ will be equivalent to to an extrinsic Euler rotation of angles c, b, a about ZYX.<br /><br />
