Mostly Based on Paul Bourkes Paper on Lines and Planes: http://paulbourke.net/geometry/pointlineplane/ and with a little help from toxic-libs for PlanePlane intersection.
Not sure why, but my add-ons don't seem to appear in the list.Have funMatthias

it's perfect. thanks a lot.
sorry for reviving that old one, but can we use it for lines / lines intersections ?Actually, I should go https://en.wikipedia.org/wiki/Bentley–Ottmann_algorithm probably...
