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
