Member Data Documentation

auto_ptr< H3D::SFInt32 > VHTK::Texture3DVolume::width

The width of the texture.

auto_ptr< H3D::SFInt32 > VHTK::Texture3DVolume::height

The height of the texture.

auto_ptr< H3D::SFInt32 > VHTK::Texture3DVolume::depth

The depth of the texture.

auto_ptr< SFTransferFunction > VHTK::Texture3DVolume::transferFunction

Mapping between volumetric data and texture values.

The texture scalars are regarded as normalized to the range 0--1 and not 0--255.

auto_ptr< H3D::SFString > VHTK::Texture3DVolume::property

The property that should be sampled to the texture.

If this field is not set, the scalar value of the scalar volume is sampled if present. If the scalar volume is not present, the vector magnitude of the vector volume is sampled.

Valid values are

• SCALAR - scalar value of the scalar volume
• GRADIENT - scalar field gradient magnitude
• VECTOR - vector magnitude of the vector volume
• CURL - vector curl of the vector volume
• DIV - vector divergent of the vector volume

auto_ptr< SFScalarDataNode > VHTK::Texture3DVolume::scalarVolume

Data to sample.

auto_ptr< SFVectorDataNode > VHTK::Texture3DVolume::vectorVolume

Data to sample.

H3D::H3DNodeDatabase VHTK::Texture3DVolume::database [static]

The H3DNodeDatabase for this node.

Reimplemented from H3D::X3DTexture3DNode.
