Member Function Documentation
Calculate the line segment PaPb that is the shortest route between two lines P1P2 and P3P4.
Calculate also the values of mua and mub where Pa = P1 + mua (P2 - P1) Pb = P3 + mub (P4 - P3) Return false if no solution exists.
Calculate distance between a point p and a line identified with segment dA,dB.
Returns distance. Also, the mu value reference tells if the nearest projection of point on line falls into segment (for mu 0...1)
Calculate distance of a point from a triangle surface.
Also computes if projection is inside the triangle. If is_into = true, Bprojected is also computed. Returns distance (positive if 'out' side, out is where points A1 A2 A3 can be read in clockwise fashion)
