Java raycasting 3D engine Horror Labyrinth

A quick video of my 3D raycaster engine written in Java. (This is not a game, but might be the basis for my next game. Who knows...)
This is an extremely early version. Don't expect to much.

Todo list:
- high res
- true color
- doors

How did you do the texture splitting? I made the raycaster, but I can't figure out how I should go about slicing images.

@VoltageEntertainment I'm not sure I understand the question.

Wall textures are actually loaded rotated by 90 degree, so pixels of the same column are next to each other in memory, which helps with caching. Trigonometry is heavily based on interpolation, there are only 2 trigonometric calculations per frame for the walls and 2 for each pixel line of the floor. Rest is done by fixed point additions (integers where the lower 8 bits are interpreted as fractions).

Any recommended books / resources for those wanting to write a similar engine from scratch? Nice vid!

I love the Giger's extures, you've used them very well. I like the lights too.
