TransferFunction2dBuilder

Creates a 2D transfer function for use with the VolumeShader and other 3D rendering constructs. The two dimensions of the transfer function are intensity on the x-axis, and gradient on the y-axis. The transfer function than thus alter fragments of a dataset based not only on the fragment's data value, but also the rate-of-change of its data value relative to its neighbouring fragments. This can be useful to help highlight boundaries between different regions or materials in a dataset.

  • Member of plug-in: Data analysis
  • Catalogue path: Data analysis/Transfer functions
Inputs:
Volume dataCSIRO::DataAnalysis::Array3dScalar

ClassificationsArrayCSIRO::DataAnalysis::TransferFunction2dClassificationA set of classification objects, each of which defines a color for a particular region of the transfer function.
Clear cached dataQDateTime

When this dependency input is updated, the gradient data cached by the operation will be cleared, enabling it to be re-generated.
