[osg-users] Rotation of a node starts clockwise and ends counter-clockwise.

[Elias Tarasov]

Hello, Sebastian!
First of all, i apologise for the very long time delay in the response. 
Somehow i didn't noticed that there was an answer to my question, and thought that nobody was interested.
Yesterday i found your last message in that thread and tried your suggestions, and they had worked.

Here is video, DOFTransform's rotation:

On a video you can see that sampling artifact/aliasing which you mentioned earlier.
However, even with the highest possible roll and having seen the scene just on the screen, the continious rotation can never be achieved.
It can be very fast, but not as smooth as it should be.

Compare to this (FlightGear is based on OSG):

My assumption here that it couldn't be done just via rotation, instead of the rotating propeller some other "blur" object must be drawn and then placed on the propeller's position.

Is that correct? 

Thank you!

Cheers,
Elia
