VKDoom adds lightmap support, so the shadows are the result of the "sunlight" that I've set up.

You'll see :)

April, hopefully.

Nope. Merely a bunch of tricks, optimizations a lot of cutting of corners.

Sorry, I don't know anything about MacOS compatibility in general. You'd have to ask on the VKDoom discord server.

the engine itself is flexible enough, but it would take a lot of time to implement.

You can already create levels for Quake and export them

Thanks. The floors and ceilings are drawn via shader, because cutting Doom sectors into triangles is rather complicated.

It works in real time, but only RTX cards can run this reasonably fast.

@@raveyardsextras4281 I got 3070, would that be enough?

Planisphere 2 by Perro Seco

According to its author is a game engine inspired by Build but written from scratch in C++.

Now imagine it in reverse What about... Quake without perspective correction?

@@retneychozken yeah, that's even more cursed!

@@retneychozken The engine's author is thinking about importing BSP files into Brahma, which means you'll be able to turn off perspective correction on them. If successful, I think it'll be very cool to see Quake maps inside a sector based engine. XD

@@usuarioextra9324 Unreal

probably just draws outside the screen bounds

There's a video on my channel that explains this type of projection in details (search for "frame postprocessing in Brahma Engine").

The sky CYLINDER

The readme file says skyboxes are unfinished right now. The engine is buggy but looks promising.

From reading the dev's notes, it doesn't seem to work that way at all. It's a custom software renderer, not triangle based. I mean, I'm not going to sit here and tell you that perspective division doesn't happen here: it has to somehow. But this thing doesn't seem to have any similarity with previous GPU-based or software renderers from the 90s. I'm kinda curious as to how it actually works.

@@HyperMario64 It is definitely curious, but the math would work out the same way either way. Perspective geometry is simply what it is, no matter how you render it. The rendering technique here is no doubt very interesting, I will grant it that.

nobody made you watch it. coding any rendering stuff is impressive even if it's not new

The renderer is a column based renderer (walls/floors are strictly drawn in vertical rows of pixels). The only way to look up and down in this kind of system is to do Y shearing: zdoom.org/wiki/Y-shearing which is what you see in the beginning of the video Afaik the perspective correction is a reprojection (done on CPU) sewn together from couple of renders with different Y shearing and FOV (to avoid wasteful rendering offscreen).

​@@raveyardsextras4281 So is it scaling the scanlines horizontally to achieve perspective? I notice on the sides that there is some artifacting on the side.

First of all this is not zdray, zdray generates lightmaps for levels. This is Vkdoom on its own, you should be able to enable it if you have an rtx card, I unfortunately don't.

@@ThatKidBobo You don't necessarily need an RTX card, since there is a fallback code, but you do need a GPU that supports Vulkan.

You can check out VKDoom's discord server if you need help: discord.gg/6hhns9HyPx

@@raveyardsextras4281 Wait you don't? I've been complete fool about this then! How do you enable this?

@@raveyardsextras4281 Hey, thanks!

Portal Prelude OST: The Hamster Alliance - Endless Chamber th-cam.com/video/G5cFu7v6NVI/w-d-xo.html

it's a gzdoom based port.

@raveyardsextras4281 good!

it's vulkan only

thanks, Pi4 gpu has vulkan-1.2 supported, build vdroom is ok. but it showed can not found vulkan devices then switch to llvmpipe software renderer. btw, can run vulkan/wayland on gzdoom 1080p very well.

A fork of gzdoom that uses vulkan and adds new features that differ from gzdoom

More like 2025 :P
