We explore the capabilities of the architecture of 3D interaction proposed in Batagelo's Ph.D. thesis in order to develop efficient and accurate mechanisms of interaction with medical volumetric data processed on the GPU. A prototype application of a curvilinear reformatting tool using direct manipulation has been implemented.

Curvilinear reformatting

Curvilinear reformatting
This illustrates our curvilinear reformatting technique using a paint metaphor to define the cropping reference surface. Only the left side of the scalp is painted by the user. All processing is performed in real-time.

Irregular cropping

Irregular cropping with distance transform
Performing irregular cropping by painting voxels of reference, then using a distance transform to label other voxels according to their distance to the voxels of reference.
