I'm sure someone more inclined to proving mathematical truities would love to describe this to you, but, for all intents and purposes, this intutitive understanding is good enough for us. We just want to make games, anyhow. +

July 2021: 3D headway (Planning)

    -
  • Explanation of Quaternions
    • +
  • Finish SAT Collision Info (very close)
    • +
  • 2D rigidbody explanation 3
  • 3D Rigid Body Collisions
  • ZIP file creator for downloads
    • +
  • Explanation of Quaternions
+

+ The last two months went almost as planned. I think I misjudged how long and how much brainpower it would + take me to write explanations for all of these things. A classic engineer mistake. We see writing, + and we think, "Easy, I can do that." And I usually can, but I am a bit rusty as of late. Additionally, this + writing involved a lot of diagrams and math equations that I struggled to put into HTML. I even had to learn + to make some simple drawings in gimp, which was a bit of a hurdle. +

+ That being said, I am fairly configdent that I can finish the above items in the month of July (maybe minus the + quaternion work, but we will see). To get my confidence up, I am going to begin with the ZIP file creator for + downloading individual projects. That will definitely be worthwhile. +
