Detailed Description

Compute a 3D represention of the volumic image. This camitk::Action uses ray casting to compute a 3D reprensentation of the volumic image. Typically, this action take a gray-level camitk::ImageComponent as an input to produce a 3D colored image.

The image computed is displayed in the 3D viewer.

To color the produced image, a transfer function is used to compute the corresponding (gray-level) => (R,G,B,alpha) values for each voxel of the image. This transfer function parameters can be adjusted thanks to the action widget.

The transfer function adjustement.
