Terminal3DGraphics

This is a little 3D engine written in Haskell that draws straight into your terminal. You can walk around the scene with keyboard input, and it all renders in true-colour using ANSI half-block characters (▀), which lets each character cell show two stacked "pixels". This works on both Linux and Windows and also exports as a library if anyone wants to make custom 3D worlds.

Features

• Movement around the worlds is done via entering keys on the keyboard and pressing enter.
• Allows for Portals with recursive views through
• Allows for selections of post processing and super sampling anti-aliasing
• Has multiple demo worlds
• Translations are selectable in the program
• Allows customizable screen size
• Pipelines auto-build versions for X64 Linux and Windows

Building the demo

To build with Cabal and have it actually run quickly

cabal build all
cabal run t3d

To run with the interpreter

ghci -isrc -iapp -package parallel -package bytestring -package transformers -package array -package deepseq -package comonad -package process app/Main.hs
:main

Using as a library

Add to your your-project.cabal:

build-depends: terminal-3d-graphics

Then in your Haskell source:

import Terminal3D
import Control.Monad.Trans.State (evalStateT)

main :: IO ()
main = do
    tex <- readBMP "myTexture.bmp"
    let tris   = cubeFormer (texWallFormer tex)
        lights = [Ray (Vec3 0.5 1 0.5), Ambient 0.3]
        world  = World (map (bakeLight lights) tris) Nothing
    evalStateT (loop world) def
