Package org.web3d.x3d.sai.VolumeRendering

Interface IsoSurfaceVolumeData

All Superinterfaces:
X3DBoundedObject, X3DChildNode, X3DNode, X3DVolumeDataNode
All Known Implementing Classes:
IsoSurfaceVolumeData
public interface IsoSurfaceVolumeData extends X3DVolumeDataNode
IsoSurfaceVolumeData displays one or more surfaces extracted from a voxel dataset.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. X3D node tooltip: (X3D version 3.3 or later) [X3DVolumeDataNode] IsoSurfaceVolumeData displays one or more surfaces extracted from a voxel dataset. A surface is defined as the boundary between regions in the volume where the voxel values are larger than a given value (the iso value) on one side of the boundary and smaller on the other side, and the gradient magnitude is larger than surfaceTolerance. Hint: IsoSurfaceVolumeData can contain a single Texture3D node with containerField='gradients' that is used to provide explicit per-voxel gradient direction information for determining surface boundaries, rather than having values implicitly calculated by the implementation. Hint: IsoSurfaceVolumeData can contain another Texture3D node with containerField='voxels' containing voxel data. Hint: IsoSurfaceVolumeData can contain multiple VolumeStyle nodes. Warning: it is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events. Warning: requires X3D profile='Full' or else include <component name='VolumeRendering' level='2'/> *


Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).
