Raycasting demo :D

[Death]

So I was bored one day and was going to make a port of a raycasting demo / proof of concept, but someone else already did it and I'm currently taking it up and making it a bit better. Currently there aren't much changes but I will be updating it as soon as I get new versions out. If you want to test stable versions of it, my website is http://www.deathprogramming.com, and you can find it under Downloads.

PICS:




^If someone could tell me how to hide those with a button that would be helpful.

I allowed the rotation to be controlled by the mouse.
Hope you don't mind.

I was already working on it and couldn't figure out how to do it properly, hope you don't mind me publishing this
EDIT - I also noticed it's not fullscreen. I don't know if you took that out or I forgot to revert change
EDIT - I saw what I messed up XD - my code was basically the same except moved a few things around and different variables but I forgot to put in dirty

I don't mind

I changed that not to be fullscreen, I don't like testing in fullscreen mode.

Cool, man!

Correct me If I am wrong, but the topic title was a bit misleading, to me.
Actually, "Raycasting" would have been a better title, not 3D Engine... As we all know, raycasting is not really 3D, just a very clever trick to fake perspective.
Nice work, it looks quite clean. Are you planning to add textures ?

[Davidobot]

I moved all variables into a table and added a FOV thingy?
Press Q to release mouse and left and right mouse buttons to increase/decrease screenDistance.

Wow, I didn't expect it to be fully drawn out of lines, awesome how easily LÖVE handles that. It gives a cool effect when you do

Code: Select all

local function redraw()
	for x = 1, w, 3 do ...

Or a higher number than 3.

We can never have enough 3D experimenting! Next step, adding textures and "things".

Thanks for the feedback - and I changed topic name.

I can't accept the FoV vision because I'm running some different code I'm working on, but if you would like to, you can keep that as your own project

This is really cool!

Is there a license associated with this? This would be a cool library to have.
