isMarkerVisible Method

Customize which markers are visible. HyperModelingDecorator determines marker visibility as follows:

  • If a marker is currently active (selected), only that marker is visible.
  • Otherwise, the marker is visible if this method returns true. The default implementation of this method determines visibility based on the SectionMarkerConfig as follows.
  • If the marker is of a type included in the config's hiddenSectionTypes, it is invisible.
  • If the marker belongs to a model not currently displayed in the viewport and the config's ignoreModelSelector is false, it is invisible.
  • If the marker belongs to a category not currently displayed in the viewport and the config's ignoreCategorySelector is false, it is invisible,
  • Otherwise, the marker is visible, unless this method returns false. The default implementation of this method always returns true

isMarkerVisible(marker: SectionMarker, decorator: HyperModelingDecorator, config: SectionMarkerConfig): boolean

see HyperModelingDecorator.requestSync to force the decorator to reevaluate marker visibility when the criterion used by your implementation of this method changes.
