Add gizmo-crt shader #413
Conversation
This shader tries to reproduce a CRT-like output without replicating mask or RGB patterns. It has the following features: - allows fractional scaling - uses texture AA shader and subpixel scaling for evenly placed sharp pixels - has a horizontal blur function which mimics bad signal quality of some systems (megadrive, psx) - has a vertical blur function which mimics n64 vertical software blur - adds some noise to mimic restless CRT colors - has a curvator function - looks good with resolutions <= 1080p - has modest system requierements https://forums.libretro.com/t/gizmo-crt-shader/41409 https://github.com/gizmo98/gizmo-crt-shader

That's an awful lot of presets. Can we pare it down to just one preset in the main CRT directory? try to do one preset per shader to avoid flooding the tree with parameter variations. An alternative could be to go to the 'shaders' subdirectory and create a 'gizmo' sub-subdirectory where the additional presets could live. |
Is being done currently? I don't see preset files in the 'shaders' subdirectory. Alternatively, what about having one preset per shader, as how we do currently, but then have something like an 'extra-presets' subdir inside 'crt' where we could go a bit wilder with shader preset variations? |
Problem is, some console behaves a little bit differently and if user does not now what psx, megadrive or n64 do, it will be hard to setup the shader.
No problem. Just tell me where i can put them. I can create a gizmo dir. |

There are some subdirs with presets in them, specifically the 'old' scalefx presets and some in the xbr directory, but it's not super-common, no. as for the 'extra presets' directory, that's pretty much the intention of the top-level 'presets' directory, though it's historically been used for combinations of multiple shaders, so the hypothetical 'gizmo' directory could go there, instead. We already have precedent for the tvout/interlacing presets being there. |
Ah, yes. That makes sense as well. But this is just a suggestion. The current organizational method works as well. I just find it less discoverable. |
Do you think a extra directory under /presets is necessary? If i had added a blur shader instead of doing it „optional“ right in the first pass, preset would go in /preset. Parts of the shader are disabled or enabled for console presets. |
|
No, it's not a necessity, I just thought you might prefer it. |
|
looks good to me :) ready for merge? |
I have checked all presets and they a running fine. Finally i wanted to squash all commits if there is nothing else open. |
|
seems fine to me. You can squash or I can squash-and-merge here. either is fine by me. |
|
It would be fine if you could squash and merge them and remove the last two commit messages. Thanks! |
