Hi all,

It seems that the Space Change VOP (and Direction Space Change VOP) are no longer available in the VEX Builder context. The docs do not say that they have been deprecated.

Are they supposed to be available? Or are we supposed to use an alternative (like Transform VOP)?

Edit: Confirmed in 10.0.430

Hi Indy,


You are correct, the space change VOP has been replaced with the Transform.

Hi,

I am not sure what I'd use it for, but spacechange could transform 4d positions and transform only does 3.
Does this limit anything at all? A little insight will be much appreciated.

Hi Indy,

I am trying to think of occasions for a vector4.

The only thing I think of is a rotation quaternion, which I would hope you have already transformed into the appropriate space. Since quaternions rarely make it to your final output image, you probably rarely come across situations for this.

If so… You could convert your quaternion to a Matrix, and then transform that….

You're right! It is a bit unclear, but hopefully you're not in any sort of 4vector world!

cheers,
