a small note made me confused.
The COLLADA specification notes that (COLLADA 1.4.1, 2nd Edition, page 5-102)
However, I haven't seen any example doing this, and it doesn't seem to be possible since channel's target is specific channel - matrix, vector, etc.Keys are often TIME values, but they can be any other variable. For example, it is possible to associate the
rotation of a wheel of a train with the position of the train on the track, so, by moving the train forward or
backward, the wheel and other mechanisms can automatically move.
Furthermore, all other tags don't support specifying input channel - such as object position, rotation, etc. Only TIME seems to be possible because it's a global variable.
Code :<channel source="#Box-Translate-X-Sampler" target="Box/Trans.X"/>
So, is there any example that uses other than TIME for sampler input? Or, is there any COLLADA implementation supporting this feature?
