@novorender/web_app / RenderStateHighlightGroups
Interface: RenderStateHighlightGroups
Highlight related render state.
Remarks
Highlight comes as a modest performance cost.
Group of objects may be visually highlighted through color transforms, hidden or filtered out. Currently, a maximum of 250 groups may be defined. Any objects that are not part of a highlight group will be treated according to the defaultAction property. This could help save memory when "everything else" needs to be hidden or highlighted.
A particular object can only be rendered using a single highlight. If the object id belongs to multiple groups, the last group in the groups array will determine how it's highlighted.
Hiding a group is more effective than using alpha=0.
Filtering of large group can greatly improve performance and memory consumption. Adding or removing objects to filtered groups will trigger a complete reload of the scene, however. It it thus recommended that this be used for relatively static groups only.
