Hidden Fields¶

isProcessing¶

name: isProcessing, type: Bool, persistent: no¶

see WEMGenerator.isProcessing

elapsedTime¶

name: elapsedTime, type: Float, persistent: no¶

see WEMGenerator.elapsedTime

id¶

name: id, type: Integer, default: 0¶

see WEMGenerator.id

autoApply¶

name: autoApply, type: Bool, default: TRUE¶

see WEMGenerator.autoApply

updateMode¶

name: updateMode, type: Enum, default: AutoUpdate¶

see WEMGenerator.updateMode

apply¶

name: apply, type: Trigger¶

see WEMGenerator.apply

clear¶

name: clear, type: Trigger¶

see WEMGenerator.clear

overwriteLabelDescription¶

name: overwriteLabelDescription, type: Bool, default: FALSE¶

see WEMGenerator.overwriteLabelDescription

label¶

name: label, type: String¶

see WEMGenerator.label

description¶

name: description, type: String¶

see WEMGenerator.description

shouldComputeNormals¶

name: shouldComputeNormals, type: Bool, default: TRUE¶

see WEMGenerator.shouldComputeNormals

workDirectlyOnInputWEMs¶

name: workDirectlyOnInputWEMs, type: Bool, default: FALSE¶

see WEMProcessor.workDirectlyOnInputWEMs

listenToFinishNotifications¶

name: listenToFinishNotifications, type: Bool, default: TRUE¶

see WEMProcessor.listenToFinishNotifications

listenToRepaintNotifications¶

name: listenToRepaintNotifications, type: Bool, default: TRUE¶

see WEMProcessor.listenToRepaintNotifications

listenToSelectionChangedNotifications¶

name: listenToSelectionChangedNotifications, type: Bool, default: TRUE¶

see WEMProcessor.listenToSelectionChangedNotifications

progress¶

name: progress, type: Float, persistent: no¶

see WEMProcessor.progress

triangulationMode¶

name: triangulationMode, type: Enum, default: Strip¶

see WEMProcessor.triangulationMode

gridCellSize¶

name: gridCellSize, type: Double, default: 1¶

Sets the level set grid size in millimeters.

Since the level set is represented as a descrete voxel grid, this parameter is important and must match the resolution of the input WEMs to produce good results.

adaptivity¶

name: adaptivity, type: Double, default: 0.2¶: Sets the adaptivity of the resulting mesh. Adaptivity == 0 means that all triangles are created at the highest resolution, while adaptivity == 1 reduces the mesh to the maximum that is supported by OpenVDB.

buildEdges¶

name: buildEdges, type: Bool, default: TRUE¶: If checked, the edge connectivity is generated.

enablePVLSupport¶

name: enablePVLSupport, type: Bool, default: FALSE¶

If checked, the module tries to find the closest node/face Primitive Value List (PVL) value from the original mesh.

This only works if the mesh modification lies in the original level set narrow-band. PVL support currently only works for triangle meshes and needs a WEM with a single patch. It is disabled otherwise and a warning is printed.

interpolatePerNodePVLs¶

name: interpolatePerNodePVLs, type: Bool, default: FALSE¶: If PVL support is enabled, this enables interpolation for the PVL values based on the barycentric coordinate of the closest triangle in the original mesh.
