To change the size based on values: check "OSPRay Use Scale Array" on "Display" section or "Properties" Tab Choose the array name you want to scale by with "OSPRay Scale Array" pulldown. Define your value to radius transfer function via the "OSPRay Scale Function" popup editor.
Note 1: the transfer function is defined to map between 0.0 and 1.0 and clamp outside of that range. Use a calculator to scale and bias into that range. If you don't like having to do this, file a feature request to remind the developers to implement it one of these days such that min is defined to be array min and max. Note 2:Cutter will not cut through the implicit spheres. Note 3: Point Gaussian representation's Use Scalar Array, Guassian Scale Array and Scale Transfer Function (which I riffed off of) are similar. I'm not sure about scale and bias and cut with this GL shader based side. David E DeMarle Kitware, Inc.
