vel.findIntersection(ref, target)
Find the intersection of a line starting in the center of the SVG node ending in the point ref
(an object of the form { x: Number, y: Number }
). target
is an SVG element to which this node's transformations are relative to. In JointJS, target
is usually the paper.viewport
SVG group element. Note that ref
point must be in the coordinate system of the target
for this function to work properly. This function returns a point in the target
coordinte system (the same system as ref
is in) if an intersection is found. Returns undefined
otherwise.
