I have 2 rays, defined by a common point and a direction vector and I want to find the point at which the normals of the 2 rays intersect at a given distance along the normals and the distance along the rays these normals start at.

enter image description here

So in this system, A is the common point of the two rays, B and C are the direction vectors, and D and E are the length of the normal vectors.

I want to find the three ? points.

    Here’s my idea

    First, define a line that is parallel to the existing line, that is, through A oriented along vector B, but is offset by vector E.

    Define a second line that is parallel to the existing line, that is, through A oriented alone vector C, but is offset by vector D.

    Find the intersection of these two new lines, this should give you the topmost ? you are looking for.
