This beam node is simply two billboards with a quad between them. The edges of the beam are rotated around the centre by the same amount as the line in screen coordinates. Requires SViewFrustum::clipLine which is part of Irrlicht 1.6. Use setPosition(start, end), the start becomes the node’s position.

todo

• Fix size of bounding box to include beam size
• Order billboard drawing so the back is always first
• Don’t draw beam when viewed from the edge
• fix a bug with the beam flipping (back facing) at some angles
• Implement clone() method and test serialization
• add a dummy node if created in an editor, so users can easily move the end point in irrEdit
