Add GPU.sb3 extension

[derpygamer2142]

This adds blocks to use compute shaders in a Turbowarp project. This uses WebGPU(which is experimental!), and only supports compute shaders. From what little research I've done it seems like it would be a pain to add any of the other types, so I'm not doing that.

• Documentation here
• Demos here
• WGSL spec here
• WebGPU spec here
• WebGPU implementation status by browser here
• WebGPU fundamentals here

Notes:

• The only thing that's somewhat undocumented(I think, let me know if I forgot something) is buffer alignment and stuff, but webgpufundamentals does a better job of that.
• This doesn't work in the packager with electron. Not sure why, a quick google search leads me to believe it's in beta.

It fails to get WebGPU adapter

what browser are you on, and what os

[derpygamer2142]

What does the extension do

it's like pen+ but with numbers instead of colors and it all happens at the same time

Chrome, Android, Why did you ask?

That would be more hard but ok

WebGPU is experimental and doesn't work on some devices. Seems like android wouldn't be supported based on webgpu.io.

Oh ok

well this is rough, make it more readable.

that's fair, I will work on that

I'm excited to see the extension coming out as it means that we could now perform GPGPU calculations on TurboWarp, meaning that 3D applications will be blazingly fast and AI is now possible.

this isn't really intended for 3d, I think vertex/fragment shader implementations such as those in webgl would be far faster than anything custom made

[derpygamer2142]

added a bunch of comments, removed profanity, and I think I reordered stuff in a way that makes more sense but I don't remember

[derpygamer2142]

i have finally updated documentation to add the 3 new blocks

[derpygamer2142]

what the sigma why lint fail

[derpygamer2142]

The latest commit(84c7b87) adds error handling in case the device was lost or the project was run before it was finished getting the adapter+device. this makes pretty much every webgpu block async, which is pretty cringe. I could alternatively:

• use .thens on the promise instead of awaiting it, removing the need for async(? not sure if this would work)
• check if the device is invalid, and if it is just don't run the block while also throwing an error
• do it anyways and add a way to check if the last block run threw an error
• have duplicates of all the blocks as an "unsafe" version which run anyways and just throw an error if something goes wrong
• force the init block to be run before you can do anything (! this would be a lot easier than the alternatives)

Should I keep it as is or do one of the above?

chose the last option as suggested
