SUMMARY

The Measure operator computes geometric properties on geometry including density, surface variation, mean curvature, curvedness, and gradient values. Results are output as point attributes for use in downstream operations.

PARAMETERS

PAGEMeasure

Group	Group	If there are input groups, specifying a group name in this field will cause this POPX to act only upon the group specified.
[+]Measure	Measure	The type of geometric measurement to compute.
Scalar Attribute	Scalarattr	The scalar attribute to compute gradient from when Measure is set to Gradient.
Use Existing Neighbors Attributes	Usenebrsattr	When enabled, uses pre-computed neighbor attributes instead of computing them.
[+]Neighbors Type	Nebrtype	Method for finding neighboring points.
Max Neighbors Distance	Maxdistance	Maximum distance to search for neighboring points.
[+]Distribution	Distribution	Method for distributing neighbor point selection.
Num Hash Buckets	Numhashbuckets	Number of hash buckets for spatial acceleration structure.
Max Neighbors	Maxneighbors	Maximum number of neighbors to consider for each point.
Smoothing Radius	Smoothingradius	Radius used for smoothing the measured values.
Output Measure Attribute	Outputmeasureattr	Name of the output attribute to store the measured values.
Output Neighbors Attributes	Outputneighborsattrs	When enabled, outputs neighbor attributes for reuse by subsequent Measure operators.

PAGEPreview Measure

Preview Measure	Previewmeasure	When enabled, visualizes the measured values using a color ramp.
[+]Measure Ramp	Measureramp	Color ramp preset used for visualizing measured values when Preview Measure is enabled.
Open Custom Ramp Editor	Opencustomrampeditor	Opens the custom color ramp editor for defining a custom measure visualization.
Reset Custom Ramp	Resetcustomramp	Resets the custom color ramp to its default state.

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.
Render Primitives	Renderprimitives	Toggles rendering of POPX Geometry or shows it as point instances only.
Convert to Point Primitives	Converttoptprim	Converts points to primitive points when Render Primitives is toggled off.
SRT / RST	Srtrst	Sets the transform order when using POPX Geometry as built-in TouchDesigner instances.
