vkDOOM3 VS 3d-game-shaders-for-beginners

For me, it was "I Am Graphics And So Can You" [1] series, where author progresses from the similar concepts up to a working renderer for DOOM 3, linked in the intro of this article [2].

Many of the vulkan presentations Kronos has given talk about this (especially the older ones), though they are also light on examples. Best specific example was the ID tech guys porting doom 3 to vulkan (I believe this may be the repo? https://github.com/DustinHLand/vkDOOM3) which they have given talks about

People can look at what's involved in the various game engines that have source available, for example this seems to be the Doom3/vkDoom3 collision detection code (UE5 has a bunch if you search for "collision"), and it's not simple to handle it. That was before (2004) nvidia even started trying to do hair/fabric as bleeding edge tech demos (geforce 5 or 6 IIRC)

I'm not a graphics programmer, but I've found these two resources to be illuminating: "How hard is Vulkan really? from GDC 2018", and id's comments in 2016 that Xbox does not use the same code paths as desktop D3D. The fellow giving the first presentation converted Doom 3 to Vulkan by himself as a starter project while on parental leave.

O3DE, the open-sourced version of Amazon Lumberyard, could, if for some reason id Tech 4 with Vulkan couldn't.

This is a great series if you’re looking for a tutorial. https://lettier.github.io/3d-game-shaders-for-beginners/inde...

Sort of.

1. I want to start with working through applying shaders to a 3d scene using the Panda3d library (https://github.com/panda3d/panda3d) . This repo covers that: https://github.com/lettier/3d-game-shaders-for-beginners.

2. Create a simple, custom, graphics-only (no collisions / physics) game engine using Entt (https://github.com/skypjack/entt) and Panda3d. The engine would rely mostly on simple inputs, like mouse clicks, and 3d graphics.

3. Configure clangd to warn on features outside C++11 then refactor both projects (1 & 2)

4. Run experiments on the game engine while working through the Vulkan book: https://raw.githubusercontent.com/Overv/VulkanTutorial/maste...

Some tutorials I have looked at (well nor originally, as I learned the basics when we were still at DX9 :D): - https://lettier.github.io/3d-game-shaders-for-beginners/index.html

Thanks! What feature would you add next? I've been thinking of implementing some of the shaders here
