that's more or less what i was doing, but it didnt gave me the
expected result, mostly because reflections and sources going out of
sight.

I'm trying to dealt with reflections tracking only points with, more
or less, the same distance between them that they had the last time I
registered them, but if you loose sight of one the ir source it acts
weird.

I'm thinking in a hybrid, acc + ir, way of achieving this.

Thank you very much, I didn't know wiibrew.org and it looks promising
