Hi,

I have a linesegment ‘v’ and I want to find a point that is at an ‘r’ distance to v and perpendicular to v(from the starting point of the line segment).Its in 2d so there will be two points on either side of the line.This can be one by solving 2 equations,one by testing dot product and other equation through distanace.Is there an efficient implementation for it???Thanks in advance.

Thanks & Regards,

brett.
