Viewport (Standard name: ViewportBase)

The Viewport node is a grouping node that specifies a set of rectangular clip boundaries against which the children nodes are clipped as they are rendered.



XML encoding
<Viewport clipBoundary='0 100 0 100'

id Name DataType PartType Default ValueType Description
MFFloat clipBoundary MFFloat inputOutput 0 100 0 100 The clipBoundary field is specified in fractions of the normal render surface in the sequence left/right/bottom/top. When the children are rendered, the output will only appear in the specified subset of the render surface.
MFNode children MFNode inputOutput Node field that contains a list of children nodes
MFNode addChildren MFNode inputOnly The addChildren event appends nodes to the children field of a grouping node. Any nodes passed to the addChildren inputOnly field that are already in the children list of the grouping node are ignored
MFNode removeChildren MFNode inputOnly The removeChildren event removes nodes from the children fieldof the grouping node . Any nodes in the removeChildren event that are not in the children list of the grouping node are ignored
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.
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.
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
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
