Re: AW: [Nuke-python] Got obj orientation from Normal pass

Doesn't that depend on the normal value at that single pixel being exactly the desired value to orientate your card with your rendered object?  So unless you rendered object was completely flat, surely the normal will be facing some other direction to the one you want?

Hey there,

That wouldn't be really easier than using the normal though.

@Hugo: What kind of normals pass do you have ? World or Cameraspace ? If the latter than you need to add
the Camera data to properly derive orientation.

Can you not just select 2 points from your position pass and work out 
the orientation from that with a bit of trigonometry?

I have made a quick tab in the Card panel to pick a color from the
position pass to place the card in the 3d space. Quite easy

But Id like to also orient the object in the scene based on the normal
pass. Is there a gizmo already made for that? If not, any hint on how
this could be acheived? Seems like I will have to deal with matric witch
I have not played with yet :)
