felixblaschke / shader Goto Github PK

Hi,

I tried to run the provided red shader example with the following command:

shader --use-remote --to-dart

It prompted me this error:

Using remote-compiler: https://shaderc.felix-blaschke.de

When checking the url, I saw that there seem to be a certificate issue:

Any workaround / fix ?

This is not an issue, I just want to tell you about flutter's great new feature!
Flutter provides a better way to compile GLSL into SPIR-V in the master branch:
flutter/flutter#93498 (comment)

This project is great. If shaderc was compiled to WASM it could eliminate the server dependency entirely and still run cross platform:

https://pub.dev/packages/wasm
https://pub.dev/packages/wasm_interop

Looks like this project is doing something like that for web:

I just have one question/curiosity if I'm not mistaken, opengl is deprecated in IOs, and I believe Apple will kill at some point and just use their new Metal API. The question is, will the glsl code work on IOS? We will be able to run these shaders without depending on the OS?
Sorry for the newbie question, I'm starting with shaders :/

Hi, I am trying to use these shaders for image processing. I've read in the flutter documentation that sampler2D is a valid uniform as an input to the shader. However I cannot find a way to generate that uniform in dart since it is not just a double. Is there a specific type for that exposed in the API?
