One of the necessities for performing real-time collision detection is to simplify a given shape. For this reason, we need to make a function that, given a set of points, will return a circle containing all the points. This simplified bounding circle can then be used to approximate a collision area:
In order to avoid adding a dependency to std::vector in Geometry2D.h, we will implement this new function using an array. The ContainingCircle function will take two arguments, one is a Point2D array, and the other deals with the number of elements in the array. The ContainingCircle function will return a bounding circle that encapsulates all of the points.
Follow these steps to implement a function that will build a bounding circle from a set of points:
Declare the
ContainingCirclefunction inGeometry2D.h:Circle ContainingCircle(Point2D* pArray, int arrayCount);
Implement
ContainingCircleinGeometry2D.cpp:Circle ContainingCircle(Point2D* pArray, int...
