Detailed Description

This is the abstract base class for all nodes containing data in the Volume Haptics Toolkit(VHTK).

Public Member Functions
	VHTKDataNode (H3D::Inst< H3D::SFNode > _metadata=0, H3D::Inst< H3D::Field > _dataChanged=0, H3D::Inst< H3D::SFBool > _scaleVectors=0)
virtual H3D::Vec3f	getVolumeSize ()=0
	Get the size of the volume in metres.
virtual string	defaultXMLContainerField ()
	Returns the default xml containerField attribute value.
Public Attributes
auto_ptr< H3D::Field >	dataChanged
	Field that indicates that data has changed.
auto_ptr< H3D::SFBool >	scaleVectors
	If this field is set to true, any vector valued property of the volume will be scaled by the parent transforms.
Static Public Attributes

virtual H3D::Vec3f VHTK::VHTKDataNode::getVolumeSize

(

)

[pure virtual]

Get the size of the volume in metres.

Implemented in VHTK::ScalarExtractorField, VHTK::VectorExtractorField, VHTK::VHTKScalarFieldNode, VHTK::VHTKScalarImageNode, VHTK::VHTKVectorFieldNode, and VHTK::VHTKVectorImageNode.

virtual string VHTK::VHTKDataNode::defaultXMLContainerField

(

)

[inline, virtual]

Returns the default xml containerField attribute value.

For this node it is "data".

Reimplemented from H3D::Node.

Reimplemented in VHTK::VHTKScalarDataNode, and VHTK::VHTKVectorDataNode.

Member Data Documentation

auto_ptr< H3D::Field > VHTK::VHTKDataNode::dataChanged

Field that indicates that data has changed.

Subclasses route to this field their fields that determine the data contents.

auto_ptr< H3D::SFBool > VHTK::VHTKDataNode::scaleVectors

If this field is set to true, any vector valued property of the volume will be scaled by the parent transforms.
