Raycasting (Doom like graphics)

[kirito1910]

Hello!
Does anyone knows if there's a way to recreate a doom like (raycasting) graphic system?



Thanks a lot!

Using raycasting on the PSX would be very inefficient, you're better off rendering the 'world' as a model like what I'm doing for my upcoming Project Scarlet 3D engine.

Thanks

Can we know more about this 3D engine?

Hi

Bisqwit makes an example about how it works while coding it and showing examples:

That's actually a really cool channel. Thanks CosmoGuy

Problem with the PSX is there is no FPU, so using floats will result in absolute horrible performance.
Everything will have to be int based.

Yea, that's a shame..
But I think it could be possible to create a map system like doom for psx. I doubt they remodelled or converted maps into TMDs when ID software created doom for PSX instead of creating a WAD file handler

They would have written a program to convert WAD's into the required data for the PSX. Take a look at the DOOM CD-ROM image and see what files are present. If you run some PSX scanner tools (PSound, PSicture, etc), it will spit out the data and tell you what it is according to those files

This should be entirely doable. There's actually a port of doom for the psx (I have it in my collection) it's an official release and everything. That being said, how it was done is beyond me, but it can be done

Edit: here's a link to a random eBay listing for it, just to show you it's a legit game http://www.ebay.com/p/Doom-Sony-PlaySta ... 5/79224814
