[Paraview] Precise clipping/slicing

[Lester Anderson]

Hello,

I have got a global dataset matrix and projected this into spherical
coordinates so I could overlay a coastline file for interpretation.

I can tweak the clipping by manual dragging but I was wondering what the
best way is to do precise clips/slices e.g. a clip at 125 degrees east or
an oblique slice that goes through know coordinates? I can see that the
method is to work out the plane position (origin, normal), but not entirely
clear on what the values represent.

I have a clip plane defined as below:

Origin: 372.352441878137   280.135672573806  -125.520109507155
Normal: 0.771596619611773  0.580503076333685  -0.260105430490818

The origin I assume refers to the plane intself in the spherical
coordinates; are the normals in radians?

This would plot through NW Australia and northwards through Timor on my
data, but it would be useful to generate a series of slices that were say
120, 125, 130 degrees etc with the clip plane oriented perfectly normal to
the sphere (if that sounds right).

Hopefully this is not a difficult one; still learning!

Cheers

Lester
