#24 Roll, Pitch, Yaw/Heading

[Anonymous]

Pitch, Roll and Turn are defined relative to the objects own coordinate system and not against a global coordinate system. In that case
maybe a good idea not to use names like Pitch, Roll and Turn but something like TurnX, TurnY and TurnZ and intergrate a real Pitch, Roll and Yaw/Heading defined against a global coordinate system.

I think that properties like these only confuse end-user. Either they should be implemented in non-ambigious way, or completely removed.

See \GLScene\Help\GLSceneTraining.chm, "Dangers of Pitch, Roll and Turn angles" topic. Citation:

Conclusion: Using Pitch, Roll or turn is useful as long as you don’t mix it’s use with the Direction and Up vector. Another important limitation is that you should not manipulate the object around more than one axis.
