I’m using the Python interface of Paraview and the Superquadric() function, being quite familiar with background equations for superquadrics [*].
However, I could not find (in ParaViewGuide-5.7.0 for instance) the exact definition of these attributes, with respect to these background equations and Paraview (x,y,z) axes. For instance:
What is the exact definition of spherical angles theta and phi used here ? (for attributes Phi/ThetaResolution/Roundness)
That is, which one is in [0;pi], and with respect to z-axis ?
What is the exact definition, with respect to half lengths along each axis, of the Scale attribute ?
My tests tell me Scale[1] (denoting Scale[0] the first value of this list…) corresponds eg to z-axis in Paraview window. Whereas I was expecting it to be along the z-axis.
It seems to me AxisOfSymmetry is not accessible from Python (not an attribute of paraview.simple.Superquadric). Christmas being close, let me say I would appreciate it to be on some WishList.
