About this game

A short demonstration of the simplest 3D graphics algorithm.



*What is RayCasting ?

-Raycasting is a rendering technique to create a 3D perspective in a 2D map.
-The basic idea of raycasting is as follows: the map is a 2D square grid, and each square can either be 0 (= no wall), or a positive value (= a wall with a certain color or texture).



*How Ray Casting Work ?
-It fires the ray from the player's spot and gets the ray's length when it touches the wall.
-From the length it calculates the size of the individual columns and their color

Minimap Legend:
Green Ray - what you see
Blue Ray - Reflection that is rendered
Yellow Ray - Reflection which didn't hit anything and is not rendered

Ratings and reviews

Cool demo! I've been reading about Raycasting recently. Interesting that devs implemented toggleable fisheye correction because it seems almost like even when it's on there's a bit of a fisheye effect still. Still a cool proof of concept though. And I assume the number in the upper left corner is the framerate? I got about 59 FPS on my S9.

Very cool app, tested various FOVs, view distances and ray counts, my phone has the same widescreen issue, but it doesn't make the app unusable. I'm surprised this is such an unknown app, reaching only 500+ downloads.

Look I'm not gonna lie this is down right cool. I know it's technically behind the current technology we have today I still really enjoy it. 10/10 I have just a little problem with the controls but that's just me. I honestly really love this stuff. 10/10 couldn't recommend it enough.
