Purpose

The SoPathTracerLines module provides rendering of thick lines in the SoPathTracer scene. The lines are rendered as cylinders with rounded caps.

The lines are gathered from the inScene Open Inventor scene and are converted from all SoLineSet and SoIndexedLineSet instances that are encountered.

This rendering shows a close-up of brain fibers rendered using thick lines.
