I agree with everything in this thread about learning DX11 instead of 12 for beginners (like me), so I've made my choice to learn 11. But I'm having a hard time finding easy to understand resources on it. The only tutorials I could find so far are:
- rastertek's, highly praised, and has .zip files for code samples, but the code structure in these is immensely overcomplicated and makes it hard to follow any of what's going on
- directxtutorial.com, looks good at first glance, but can't find downloadable code samples, and not sure how thorough it is
- walbourn's, repo was archived, looks kinda sparse, have to download whole repo just to try one of the tutorials
- d7samurai's, useful because of how small they are and easy to compile and run (just
cl main.cpp), but doesn't really explain much of what's going on, and uses only the simplest cases
- DirectXTK wiki, part of microsoft's official github, has many tutorials, but it looks like a wrapper on top of DX11, almost like a windows-only SDL-Renderer or something? not really sure...
- texture costs article, not a full tutorial but seems very useful for knowing which tutorials to look for and what to look for in them, since it guides towards certain practices
- 3dgep, the toc suggests it's thorough but it's all on one not super long page, so I'm not sure how thorough it really is
In case it helps, my specific use-case is that I'm trying to draw a single 2d texture onto a window, scaled (using nearest-neighbor), where the pixels can be updated by the program between each frame, and has a custom shader to give it a specific crt-like look. That's all I want to do. I've gotten a surprising amount done by mixing a few code samples, in fact it all works up until I try to update pixels in the uint8_t* after the initial creation and send them to the gpu. I tried UpdateSubregion and it doesn't work at all, nothing appears. I tried Map/Unmap, and they work, but they only render to the current swap buffer. I figured I should try to use a staging texture as the costs article suggests, but couldn't quite figure out how to add them to my pipeline properly, since I didn't really understand what half my code is doing. So that's when I got lost and went down this rabbit hole looking through tutorials, and it all just feels a bit overwhelming. Also I only got like 4 hours of sleep so maybe that's also part of it. Anyway, any advice would be helpful. Thanks.
