Constructor for IsoSurfaceVolumeData

Name Type Argument Default Description
ctx Object <optional>
null context object, containing initial settings like namespace


These are the X3D / X3DOM fields of this node. Values should usually be received / set as strings via DOM functions (i.e., using setAttribute("myFieldName", "myFieldValue") and getAttribute("myFieldName")).
Name Type Default Value Range Inheritance Standard Description
allowViewpointInside SFBool true X3DVolumeDataNode Allow to locate the viewpoint inside the volume.
appearance SFNode X3DAppearanceNode X3DShapeNode Holds the appearance node.
bboxCenter SFVec3f 0,0,0 [-inf, inf] X3DBoundedObject Center of the bounding box
bboxSize SFVec3f -1,-1,-1 [0, inf] or -1 X3DBoundedObject Size of the bounding box
contourStepSize SFFloat 0 The countourStepSize field specifies an step size to render isosurfaces that are multiples of an initial isovalue. When this field is non-zero a single isovalue must be defined on the surfaceValues field.
dimensions SFVec3f 1,1,1 X3DVolumeDataNode Specifies the size of of the bounding box for the volume data.
geometry SFNode X3DGeometryNode X3DShapeNode Holds the geometry node.
gradients SFNode Texture The gradients field allows to provide the normals of the volume data. It takes an ImageTextureAtlas of the same dimensions of the volume data. If it is not provided, it is computed on the fly.
isPickable SFBool true X3DShapeNode Defines whether the shape is pickable.
metadata SFNode X3DMetadataObject X3DNode Field to add metadata information
render SFBool true X3DBoundedObject Flag to enable/disable rendering
renderStyle MFNode X3DVolumeRenderStyleNode The renderStyle field contains a list of volume render style nodes to be used on each isosurface.
surfaceTolerance SFFloat 0 The surfaceTolerance field is a threshold to adjust the boundary of the isosurface.
surfaceValues MFFloat 0] The surfaceValues field is a list containing the surface values to be extracted. One or multiple isovalues can be declared.
visible SFBool true X3DBoundedObject Flag to enable/disable rendering, alias for render
voxels SFNode Texture X3DVolumeDataNode The voxels field is an ImageTextureAtlas node containing the volume data.
