SUMMARY

The Clip operator cuts plain POP geometry the way a Clip SOP does. Triangles and quads that cross the cut get new points on the crossing edges and are re-triangulated, so the boundary is exact instead of stepping by whole primitives, and the seam is fused so the cut edge stays watertight.

Clip By Plane uses a list of Plane blocks, each placed by Origin and Direction or by Translate and Rotate and offset by Distance, cut in turn; Clip By Attribute follows the iso-contour of a point attribute at Clip Value, so a POPX falloff can shape the cut. Keep the Above side, the Below side, or Both tagged in groups, and use Snapping Tolerance to avoid slivers near the cut.

PARAMETERS

PAGEClip

[+]Clip By	Clipby	Choose how to cut: by the clip planes, or along the iso-contour of a point attribute at Clip Value.
Plane	Plane	Clip planes. The geometry is cut by every enabled plane in turn.
Enabled	Plane0enabled	Enable this plane.
[+]Orient Plane With	Plane0orient	Direction uses the Origin and a normal Direction. Transform rotates and translates the XZ plane, normal +Y.
[+]Origin	Plane0origin	Sets a point on the plane in Direction mode.
[+]Direction	Plane0direction	Sets the plane normal in Direction mode. The side it points to is above.
[+]Translate	Plane0translate	Sets the position of the plane when Orient Plane With is Transform.
[+]Rotate	Plane0rotate	Rotate the plane in XYZ order, starting from the XZ plane with normal +Y. Used in Transform mode. Angles are given in degrees.
Distance	Plane0distance	Offsets the plane along its normal.
Display Guide	Displayguide	Draw the clip planes in the viewer. The guide is never rendered.
[+]Display Color	Displaycolor	Sets the color of the clip guide.
[+]Attribute	Attr	The point attribute the cut follows. The first component is used.
Clip Value	Clipvalue	Attribute value the cut runs through. Higher values are above the cut.
[+]Keep	Keep	Side of the plane to keep. Both keeps everything, cut, with each side in its own point group.
Snapping Tolerance	Snaptol	Points closer than this to the cut snap onto it instead of being cut, to avoid slivers.
Above Group	Abovegroup	Point group for the above side of the cut, used when Keep is Both.
Below Group	Belowgroup	Name of the point group for the below side when Keep is Both.
Copy Topology Info Back to CPU	Cpureadback	Enable copying the point count and topology information held on the GPU to the CPU.

PAGECommon

Bypass	Bypass	Pass through the first input to the output unchanged.
Free Extra GPU Memory	Freeextragpumem	Free memory that has accumulated when output memory has grown and shrunk.
