Hello,
This is a 2D problem in the x, y plane.
My inputs are:
circle radius (same for both circles A & B)
center point for circle A
center point for circle B
What I want to find are:
The corner points of the rectangle that satisfies the following:
The four points lie on the circles (2 on each circle, at opposite ends
of a diameter) such that
2 sides of the rectangle are parallel to the line that joins the center
points of the circles.
The other two sides of the rectangle are diameters of the circles.
I need to run this repeatedly as the mouse moves, so I am looking for a
fairly efficient way to calculate the four corners of my rectangle.
Thank you,
Ted Hill
