Get Data Polyline

VolumeViz Demonstrates how to extract and use a polyline of data out of a SoVolumeData by using SoLDMDataAccess class API.

This program displays several segments build from data extracted out of the given volume. To update the second viewer, move the dragger plane in the main viewer. Lines are automatically updated in the second viewer. Changing data access mode (Direct, Direct and prefecth, Cache) will change the amount of memory allowed to LDM. As a result, the main volume will show a different resolution. This program demonstrates that even with low memory settings, data access can reach full resolution in Direct and Direct and prefetch mode.
