Converting a 3DMax quaternion to a OpenGL quaternion
Author
Please help me with this topic - i have already tried to exchange z/y axes, change rotation sign - nothing works...
If you're using the IGame / 3DXI interface, it has a conversion manager which might come in handy:
Take a look at the help file that comes with the Max SDK.
GameConversionManager * cm = GetConversionManager();cm->SetCoordSystem(IGameConversionManager::IGAME_D3D);Take a look at the help file that comes with the Max SDK.
Have you tried making no change at all?
There is no such thing as an OpenGL quaternion as far as I know, if you think you must do a conversion because you have to transpose matrices, you are wrong.

Note that quaternions, like any other rotation or linear transform, are not "handed" (as in left-handed vs right-handed). Handedness of a coordinate system comes from the interpretation of the numbers in physical space. No matter what the handedness convention, rotating the X vector 90 degrees around the Z vector will yield the Y vector -- the math and numbers are the same.
