Detailed Description

Decomposes rotation values.

This engine takes as input a rotation, and decomposes it into an axis value and a rotation angle (in radians).

The input can have multiple values, allowing the engine to decompose several rotations in parallel.

File Format/Default

: DecomposeRotation {

rotation 0 0 1 0

}

SoDecomposeRotation::rotation
SoMFRotation rotation
Rotation to be decomposed.
