A quick start of WebGPU

I followed the your-first-webgpu-app and finished the course in my spare time.

And the result is as follows:

The code is quite straightforward, but why I wrote this blog is that I was inspired by the course.

So, the takeaways are as follows:

• A compute shader is an effective way to leverage the GPU for calculations. Sometimes, we don’t have ready-made solutions for certain scenarios. Reflecting on this reminds me of when I used the CPU for similar calculations in the past.

• Ping-pong buffer usage: I have occasionally experimented with this type of buffer in my projects. In the past, I relied on approaches involving mutexes or semaphores to manage the pipeline. However, knowing about this buffer and its name earlier could have saved me considerable time. With the proper terminology, I could have directly searched for and adopted useful design patterns instead of reinventing the wheel in a naive way.
