+ <h1>May/June 2021: More Collisions</h1>
+ <ul>
+ <li>SAT Collisions for Convex Polygons with Explanation</li>
+ <li>Pill Collisions</li>
+ <li>Remove (or hide) ellipse collision pages for now</li>
+ <li>3D scene setup</li>
+ <li>3D scene basic physics with spheres bouncing around a scene</li>
+ </ul>
+ <p style="font-size: 18px;">
+ Obviously, the month of April did not go as planned. I got caught up with a number of tasks that I couldn't handle,
+ namely, the pill collisions. These, as I discovered, were quite unfeasible and involved a lot of complex maths
+ that I didn't quite yet understand. They are also unreasonable for game development's sake, so I will ditch that
+ effort and focus on doing other things. This, of course, is not time entirely wasted, as I now I have a somewhat
+ better understanding of why ellipses (and by extension ellipsoids, although I am not entirely sure of this). I should
+ <i>instead</i> try to figure out the intersection using pills, not ellipses. Pills are simply 2D shapes made of a
+ rectangle in the middle and two half-circles at either ends. This is a far less expensive collision to calculate.
+ <br/><br/>
+ I also failed when it came to getting a good physics collision system going. This stemmed from a general misunderstanding
+ of moment of inertia and how it can properly be implemented for each shape. I think I am getting a better grip on it now,
+ however.
+ <br/><br/>
+ And that brings me to May/June. I am combining these two months because I am quite busy in May with family stuff,
+ and hence won't be able to give my full attention to the project. That being said, as a high-level goal, I hope to
+ get some more 2D collisions going, and maybe move onto 3D fairly soon. For 3D, I would simply like to get the physics
+ simulation up and running with simple objects (spheres, cubes, etc.). From there, I want to begin exploring more complex
+ physics simulation topics like oct-trees, multiple collision resolution, etc. We will see what happens, but I am optimistic,
+ so long as I stay the course.
