WEMDemergePatches¶

MLModule¶

genre	`WEMProcessing`
status	`stable`
author	`Olaf Konrad`

keywords	`WEM`, `separate`, `connected`, `components`

Purpose¶

The module WEMDemergePatches splits a WEM into connected components and offers the possibility to remove certain parts of those separated WEMPatches.

Details¶

The module scans the input WEM for connected components. For each connected component, a WEMPatch is generated, and the geometry stored in there.

This list of WEMPatches (connected components) can be purged by adjusting the purge mode and limit.

The following purge modes are available:

Num Nodes, Num Edges, Num Faces, Primitives Percentage
Area mm², Area cm², Area m², Area Percentage
Volume mm³, Volume cm³, Volume ³, Volume Percentage

A purge limit of 0 disables the purging which is the default.

Visible Fields¶

Auto Apply¶

name: autoApply, type: Bool, default: TRUE¶: If checked, all parameter changes lead to a new computation.

Auto Update¶

name: autoUpdate, type: Bool, default: TRUE¶: If checked, all changes to the input WEM lead to a new computation.

Apply¶

name: apply, type: Trigger¶: If pressed, the module demerged and purges the input WEM.

Label¶

name: label, type: String¶: Sets a label that can be set to the output WEM.

Description¶

name: description, type: String¶: Sets a descriptive text that can be set to the output WEM.

Generate Edges¶

name: generateEdges, type: Bool, default: TRUE¶: If checked and the input WEM has no edges computes yet, edges are computated in the output WEMPatches.

Limit¶

name: limit, type: Float, default: 0¶: Sets the limit for purging WEMPatches. A value of 0 means no purging.

Patch List String¶

name: patchListString, type: String¶: Shows all demerged patches and information about them in this string.

Purge Mode¶

name: limitMode, type: Enum, default: PrimitivesPercentage¶: Defines the purge mode that is active if the Limit is greater than 0.

Values:

Title	Name
Num Nodes	NumNodes
Num Edges	NumEdges
Num Faces	NumFaces
Primitives Percentage	PrimitivesPercentage
Area SMM	AreaSMM
Area SCM	AreaSCM
Area SM	AreaSM
Area Percentage	AreaPercentage
Volume CMM	VolumeCMM
Volume CCM	VolumeCCM
Volume CM	VolumeCM
Volume Percentage	VolumePercentage

Use Primitive Value List¶

name: usePrimitiveValueList, type: Bool, default: FALSE¶: If checked, the module does not scan for connected components anymore but rather for nodes with a Primitive Value List value in a given range.

Primitive Value List Name¶

name: primitiveValueListName, type: String, default: LUT¶: Sets the Primitive Value List which is used as a look up for the value range.

Primitive Value List Range¶

name: primitiveValueListRange, type: Double, default: 1¶: Sets the range for the PVL values to lead to a separation into WEMPatches.
