Detailed Description

This class implements triangles-based intersection calculation. Usage: 1) call initializeCalculations() 2) add triangles: 2.1) call appendTriangleContainer to obtain containerID 2.2) call addTriangleToContainer with obtained ID 3) specify containers that should be tested by calling addContainerToBeTested and call processPathCalculation for them 4) call computeIntersections to calculate intersections between specified container and all "should be tested" containers 5) use processPathCalculation() to obtain results

Library: Source code provided.
