compute.toys's Issues

Bug: blue-noise in wrong gamma space

I found a bug in compute.toys (it seems);

The texture provided in compute.toys, blue-noise (the last one), is not stored in linear space but has been mapped to gamma space;

Because the distribution of blue-noise between 0.0 ~ 1.0 is unbiased, the number of pixels >0.5 should be roughly equal to the number of pixels <=0.5;

However, the blue-noise provided by compute.toys obviously does not conform, as shown in the picture:

The left side is <= 0.5, the right side is >=0.5;

Only by applying a gamma correction of pow(blue_noise, 1 / 2.2) can the correct image be obtained;

So I suspect that an incorrect gamma mapping, pow(color, 2.2), was added when generating the blue-noise.

FR: disableable code recommendations popup in editor

UI: Record button looks like it's disabled

The black "record" button icon blends into the dark background. When I did notice it, it's seemed like it was disabled (until I clicked on it).

Bug: allow spaces between type and size `#storage array<type, size>`

Error occurs when using as standalone editor

Attempted to use the compute.toy as a standalone editor by following the steps described in the README file, which involved deleting the pages directory before starting the server. Unfortunately, this approach did not work.

I then tried to resolve the issue by clearing the cache, which involved deleting the .next directory. However, even after doing this, I consistently encountered the following error:

Server Error
Error: useAuth must be used within an AuthProvider

This error happened while generating the page. Any console logs will be displayed in the terminal window.

Could you please provide guidance on how to resolve this issue?

FR: slider for time variable

Bug: undo history goes back up to the default shader code when having opened a shader.

FR: Support Open Graph protocol

We should add open graph meta tags to the website

The following tags should be added to the <head> of every page

<meta property="og:title" content="...">
<meta property="og:type" content="...">
<meta property="og:image" content="...">
<meta property="og:url" content="...">
<meta property="og:description" content="...">
<meta property="og:site_name" content="...">

This allows apps like Discord to generate previews for links to the website

Remove or replace wee_alloc

See rustwasm/wee_alloc#106

I'll happily submit a PR for this

Bug: too many shader compilations

check dev console on page load.

Minor bug: website asking to save saved shader

Bug: update to current wgsl spec

All current limitation related to public/grammars/wgsl.ts file. For example #36 PR gives ability to use override in shaders.

We need to update it to:
https://www.w3.org/TR/WGSL/#grammar-recursive-descent
https://www.w3.org/TR/WGSL/#statements-summary
https://www.w3.org/TR/WGSL/#expression-grammar
https://www.w3.org/TR/WGSL/#var-and-value-decl-grammar
https://www.w3.org/TR/WGSL/#type-specifiers

Alert on route change while shader is being edited.

Can't test it locally, but I believe something like this would work - https://betterprogramming.pub/prevent-route-changes-and-unsaved-data-loss-in-next-js-f93622d73791

Rust code does not build due to proc_macro2 dependency

cached depends on an old version of proc_macro2, which suffers from rust-lang/rust#113152
I suppose updating all the dependencies would be in order.

As a side note, this message also appears.

warning: `D:\Coding\GitHub\Libraries\compute.toys\wgpu-compute-toy\.cargo\config` is deprecated in favor of `config.toml`
note: if you need to support cargo 1.38 or earlier, you can symlink `config` to `config.toml`

I'll happily submit PRs to fix this.
