[x3d-public] Euler rotation

[vmarchetti at kshell.com]

There is no single node Euler angle alternative representation of a rotation transform defined in the current (v 3.3) X3D standard.

You can get an easier to edit representation of Euler angle rotation (specifically the Tait-Bryan angles, https://en.wikipedia.org/wiki/Euler_angles#Tait%E2%80%93Bryan_angles <https://en.wikipedia.org/wiki/Euler_angles#Tait%E2%80%93Bryan_angles>, commonly used for vehicle oriented
with respect to the horizon, by nesting 3 Transforms:

<Transform DEF="yaw-rotation" rotation="0 0 1 $yaw">
<Transform DEF="pitch-rotation" rotation="0 1 0 $pitch">
<Transform DEF="roll-rotation" rotation="1 0 0 $roll">
<!-- put vehicle model here -->
<Shape>...</Shape>
</Transform>
</Transform>
</Transform>

where for $yaw, $pitch, $roll you need to substitute the numerical value of the rotation angle in radians.
