# Pokitto Ray Casting Demos
|
|
|
|
These are demos showing ray casting (pseudo) 3D rendering technique using
|
|
raycastlib (a Pokitto-independent C library I made along with this project) on
|
|
a small gaming console Pokitto.
|
|
|
|
There are these demos:
|
|
|
|
- helloRay: Hello world program showing the very basic usage of raycastlib
|
|
on Pokitto. If you want to learn about the code, start here.
|
|
- demo1: Showoff RPG-like program demonstrating most raycastlib features.
|
|
- demo2: Classic "flat/1D" ray casting program in a sci-fi mood.
|
|
- demo3: Minecraft-like demo with procedurally generated editable world.
|
|
|
|
Included are also other tools I created, such as Python scripts for image
|
|
conversion to the format I use. Everything should be sufficiently commented.
|
|
|
|
The last three demos use common definitions from the general.hpp file. This
|
|
file contains some useful resources that you can use in your own game. You can
|
|
of course as well create a game by expanding any of the demos.
|
|
|
|
There are a lot of compile-time options you can try out, like turning various
|
|
effects on/off, setting the rendering quality etc. Check out the defines at
|
|
the beginning of each source code file.
|
|
|
|
This repository contains the version of raycastlib that I tested the demos
|
|
with, but you can find the most recent version of the library among my other
|
|
repositories.
|
|
|
|
The demos use display Mode13, i.e. 110x88 with 256 colors. I recommend you use
|
|
this mode for your games, but the other ones are an option too. I created a
|
|
custom general 256-color HSV-based palette that allows for fast brigtness
|
|
manipulation of colors, which is important for fog/dimming. Reusing this
|
|
palette (or modifying it) will most likely be the best option for your project.
