VOP Cop2 Filter workflow May 27, 2018, 6:50 p.m.

As much as I am comfortable working in wrangles in SOPland, using VOP Cop2 Filter network is a bit of a beast for me.

The setup I have works as is, but I would like to use the Max and Min nodes I have in the network too;

I want to use the single maximum and single minimum value of the red as the range of the fit nodes source inputs.

I'm assuming I can't just hook up the Max/Min nodes as the network is running over pixels in much the same way as what would happen in a point wrangle(run over points)?

Therefrom each pixel in this case has their Max/Min being the same as there is only one pixel being sampled for each iteration?

In SOPland I would get around something like this by first creating a detail attribute, from runnning in detail mode of a wrangle, and import that value to use as reference in the next wrangle.

Help is appreciated - Thanks.

P.S. The pic being used is the Houdini default butterfly so my hip should open for anyone looking at it.

Even though you still can write hscript/python expressions in the Constant value fields in your node.

When it comes to utilizing the local variables I think you have to use the VEXpression with these new point nodes,

like what I did from the docs equivalent examples;

You have 3 three different catagories defining the motion.

@orient based and pscale - I've added a fit for that so you can better control larger pscales relative to the others.

Your have arc divisions - I've separated out a circle for each point so you can control each one by changing the keyframe/or chop.

Transforms - driven by chops for each circle.
