Purpose

The module GVROrthoView2D provides a 2D view displaying the input image or GVR octree volume data in three orthogonal viewing directions.

Additionally, slab viewing is possible. In contrast to the module OrthoView2D, the image/octree is displayed by a SoGVRVolumeRenderer node and not by a SoView2D node. No ML cache is used. Once the octree is created, reformatting and thus slicing through the orthogonal views is fast.

Usage

Connect either an ML image or a GVR octree as an input. If both are connected, the octree is used.

Use the left mouse button to set a position in the data set. This position will be displayed in all available views.

See also View2D description for basic viewing functionality.
