BoundaryEnhancementVolumeStyle

Provides boundary enhancement for the volume rendering style. In this style the colour rendered is based on the gradient magnitude. Faster changing gradients (surface normals) are darker than slower changing. Areas of different density are made more visible relative to parts that are relatively constant density.

id Name DataType PartType Default ValueType Description
SFFloat boundaryOpacity SFFloat inputOutput 0 [0, inf) the amount of the gradient enhancement to use
SFBool enabled SFBool inputOutput TRUE The enabled field defines whether this rendering style should be currently applied to the volume data. If the field is set to FALSE, then the rendering shall not be applied at all. The render shall act as though no volume data is rendered when set to FALSE. Effectively, this allows the end user to turn on and off volume rendering of specific parts of the volume without needing to add or remove style definitions from the volume data node.
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
SFFloat opacityFactor SFFloat inputOutput 1 [0, inf) power function to control the slope of the opacity curve to highlight the dataset
SFFloat retainedOpacity SFFloat inputOutput 1 [0, 1] the amount of initial opacity to mix into the output
SFNode surfaceNormals SFNode inputOutput NULL [Texture] The surfaceNormals field is used to provide pre-calculated surface normal information for each voxel. If provided, this shall be used for all lighting calculations. If not provided, the implementation shall automatically generate surface normals using an implementation-specific method. If a value is provided, it shall be exactly the same voxel dimensions as the base volume data that it represents. If the dimension are not identical then the browser shall generate a warning and automatically generate its own internal normals as though no value was provided for this field.
