Data

Name Description Default value
name object name unnamed
printLog if true, emits extra messages at runtime. 0
tags list of the subsets the objet belongs to
bbox this object bounding box
componentState The state of the component among (Dirty, Valid, Undefined, Loading, Invalid). Undefined
listening if true, handle the events, otherwise ignore the events 0
inputPoints Position coordinates (3D, z=0)
inputEdges Constraints (edges)
inputEdgesData1 Data values defined on constrained edges
inputEdgesData2 Data values defined on constrained edges
seedPoints Seed Points (3D, z=0)
regionPoints Region Points (3D, z=0)
useInteriorPoints should inputs points not on boundaries be input to the meshing algorithm 1
outputPoints New Positions coordinates (3D, z=0)
outputTriangles List of triangles
outputEdges New constraints (edges)
outputEdgesData1 Data values defined on new constrained edges
outputEdgesData2 Data values defined on new constrained edges
trianglesRegion Region for each Triangle
outputBdPoints Indices of points on the boundary
shapeCriteria Shape Criteria 0.125
sizeCriteria Size Criteria 0.5
viewSeedPoints Display Seed Points 0
viewRegionPoints Display Region Points 0
Name Description Destination type name
context Graph Node containing this object (or BaseContext::getDefault() if no graph is used) BaseContext
slaves Sub-objects used internally by this object BaseObject
master nullptr for regular objects, or master object for which this object is one sub-objects BaseObject
