The intersection of two planes is a straight line, provided that the planes are not the same or parallel.
Intersection
Checking for the intersection of geometric shapes is useful for collision detection.
This page explains how we can check for intersection of primitive shapes like:
- Lines
- Circles
- Triangles
- Rectangles (axis aligned and not)
There are approaches for more complex shapes, we can make the shapes from these primitives, we can also use the primitive shapes as a boundary around an object. Bounding shapes can be used as a quick check to eliminate the need to do more complex intersection tests on shapes that are not close.
