title: How to detect if an ellipse intersects(collides with) a circle
body: <p>I want to improve a collision system.</p>
  
  <p>Right now I detect if 2 irregular objects collide if their bounding rectangles collide. </p>
  
  <p>I want to obtain the for rectangle the corresponding ellipse while for the other one to use a circle. I found a method to obtain the ellipse coordinates but I have a problem when I try to detect if it intersects the circle.</p>
  
  <p>Do you know a algorithm to test if a circle intersects an ellipse?</p>
