Finding intersecting points in the Lissajous scan pattern
显示 更早的评论
Hi.
I'm trying to find the intersecting points in the Lissajous scan pattern.
For
x = A * sin(2*pi*f1*t)
y = B * sin(2*pi*f2*t+pi/2)
drawing the Lissajous scan pattern itself was not that difficult,
but I had a lot of trouble finding out the intersecting points.
Does anyone have any experience with this problem?

There are several options available in FEX -
You could also go through this forum and find different approaches for finding intersections of 2 curves (mostly utilizing interp1), as this type of question has been asked many times.

In this question, we're trying to find the points where a single parametric curve intersects itself. That doesn't seem as simple as the typical request.

(If I understood your point clearly, @DGM) The 2nd FEX submission can be used for finding self-intersections points as well.
