Let's set up an equation to find both points of intersection between a line and a circle, but do it in a way that makes it easy to tell which one (if either) lies between the terminating point and the starting point of your vector. Definition Suppose our equation of the circle is ...

PURPOSE:To surely extract a large circle intersection corresponding to a line segment near a camera by selecting a higher density out of the density in a window and a second virtual surface density, writing it to a first virtual surface, and updating the first virtual surface. CONSTITUTION:The...

2. If a plane intersects a cylinder, then the intersection must be a circle. True or False: If the line which bisects an external vertical angle of a triangle is parallel to the base of the triangle, then the triangle is isosceles. True or fa...
Line Intersection is much simpler than clipping (#4), at least if we don't care for the difficult cases. It would be useful, for example, in quadtree.findInPolygon (d3/d3-quadtree#30 & https://observablehq.com/d/54a6e96b6630b0d9). [EDIT]...
