New in this update: more terrain, new graphics, and a render mode. This is the last progress video of Project 3D.

~~~~ What is this? ~~~~
This is not Mine Blocks 3, but it definitely serves as good practice for programming in a 3D environment. Mine Blocks 3 will be a lot different :) This particular project was to experiment with my raytracing abilities.

I coded the "3D raycaster" engine from scratch. It was originally coded in AS3, however it was then ported to Java (what you're seeing right now is Java). I would like to thank my friend GhostID for helping me port it to "Slick2D" rather than just plain Java. It seems to have helped a lot. Unfortunately though, due to my render method, it's not as practical as it looks. *Typically* raytracing is used as rendering, not real time gaming.

~~~~ Why is the quality so low? ~~~~
Raycasting requires each pixel to act like a ray and test collisions in a 3D data structure. More pixels = more rays = more collision detection. The CPU simply cannot handle this much data (especially with how unoptimized my code probably is).
As you see later in the video, I stop the camera and let it sweep-render a few times, making the image a lot more clear. It is going as fast as it can. Clearly the speed is not optimal for real time gaming haha!

~~~~ What's next? ~~~~
Again, this is the last progress video of Project 3D. I learned a lot in the process, and I'm super proud of myself for getting as far as I did... but it'll soon be time to move on to bigger and better things. I hope to continue learning Haxe and build a proper 3D engine capable of being much more amazing!
