there are no "bad looking transformations" in sight, and these meshes aren't spheroid or cuboid at all.
I shall wait for your new mobj.h, because the one i am using doesn't preserve the correct axis alignment as you can see on the attached screen shot.

Patrice,

You aren't using the values correctly. You are supposed to use +-1/0 or +-1.f/0.f to specify the optional rotation directions and axes, just like when using glRotate().

glRotate() normalizes non-nulls to +-1.f, which #rotate doesn't do. I warned you about that because I thought you might find some interesting usages for this effect. But regretfully, you didn't:

If the array values are other than those two, the mesh exhibits strange scaling effects. But I think you may find them amusing and probably useful too in some of your future implementations. :D

No big thing tho. I can apply normalization to non-nulls when parsing the #rotate meta.

Would it be possible to have the change(s) you have done in mobj.h, to avoid me to use an extra hidden circle around the objects ?

Thank you.

Don't you think that we could release officially version #2.52.
New SyncTimer
New #rotate meta
both seems to be quite reliable for now, then i could post updated animated projects showing the rotation feature in context.

Your thought ?

Yes, please do, Patrice.

But if somebody wants the sources, I think it will be reasonable to provide the older mobj.h (the way it was in my latest zip) -- without the attempted #group meta. It isn't working yet as I think it should, so its implementation may change with time, and until then it's going to be just dead code.
