SplitGroup

Determines if and how view frustum shall be partitioned into several parts to avoid z-fighting artifacts due to limited depth-buffer precision. Node can be used as child of any ViewBindable.

id Name DataType PartType Default ValueType Description
MFFloat zSplit MFFloat inputOutput z-positions; ordered list starting from zNear up to zFar (in- or exclusively depending on 'useCameraNearFar'); used for rendering scene in several bins
MFString logFeature MFString inputOutput state, child, parent, route, eventIn, eventOut controls the logging of changes, state: log state changes (e.g. live), child: log child add/remove, parent: log parent add/remove, route: log route add/remove; eventIn: log receiving of events, eventOut: log sending of events: guiView, runtime system should create node-view, guiEdit: runtime system should create node-editeverything: log everything
SFBool render SFBool inputOutput TRUE Flag to control the visibility of the node or subtree
SFBool showBBox SFBool inputOutput FALSE Show Bounding Box of Subtree.
SFBool useCameraNearFar SFBool inputOutput FALSE if true, the outer bounds of the values in zSplit (namely zNear/zFar) are taken directly from the camera, which also allows using the automatically calculated values
SFFloat numBins SFFloat inputOutput 1 if zSplit field empty, numBins is used to automatically partition scene into numBins parts
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
SFString partitionType SFString inputOutput auto [auto, linear, logarithmic] if zSplit field empty, partitionType defines how scene is subdivided into numBins parts (e.g. linear)
SFVec3f bboxCenter SFVec3f initializeOnly 0 0 0 Bounding box center: position offset from origin of local coordinate system.
SFVec3f bboxSize SFVec3f initializeOnly -1 -1 -1 Bounding box size: automatically calculated, can be specified as an optimization or constraint.
