Hi,

where are the definitions of "order" in R13 for methode HPBToMatrix??

_<_dt id="c4d.utils.hpbtomatrix"_>_ c4d.utils.HPBToMatrix( hpb , order )
e.g. utils.HPBToMatrix(myhpb,c4d. ROT_YXZGLOBAL) will result in "module object has no attribute 'ROT_YXZGLOBAL'.

And if I set direct numeric values from R12, the effect in R13 is not the same as in R12:

eg.: utils.HPBToMatrix(myhpb,0 _)

Has anybody an idea?

I can only confirm that it does not work as before.
We do need SDK snippets asap for this and the new SplineGUI.

It looks like the new definitions are found in the coffee.h file.

EXAMPLE:

c4d.utils.HPBToMatrix(myhpb, c4d.ROTATIONORDER_ZXYGLOBAL)

Ah, good call.
Interesting how the rotations are based from the vector….
v.x = pitch
v.y = heading etc…

Jepp, this is fine. Thank you! Now my plugin works well with R13.

To keep scripts compatible with R12 we now have to make extra code:

  
      if (c4d.GetC4DVersion()>=13000) :  
          c4dROT_HPB=c4d.ROTATIONORDER_HPB  
          c4dROT_YXZGLOBAL=c4d.ROTATIONORDER_YXZGLOBAL  
      else:  
          c4dROT_HPB=c4d.ROT_HPB  
          c4dROT_YXZGLOBAL=c4d.ROT_YXZGLOBAL  

...and we have to exchange first and second component of the vector...

  
              if (c4d.GetC4DVersion()>=13000) :  
                  v=c4d.Vector(cmd['y'],cmd['x'],cmd['z'])  
              else:  
                  v=c4d.Vector(cmd['x'],cmd['y'],cmd['z'])

It looks as if:
HPBToMatrix(vector) still can be used (only 1 argument)
Is this a legacy mode that will be dropped at a time later?

Also, are we sure the "swapped" x and y vectors are correct and not a bug?

PS.
R12 GetOptimalAngle(vectorA , vectorB)
is changed.
It now need a 3:rd argument, rotation order to run (no legacy mode)
R13 is:
GetOptimalAngle(vectorA , vectorB, c4d.ROTATIONORDER_XYZGLOBAL)
I haven't checked if the vectors are swapped as in the HPBToMatrix()
