Ah yes, surely those 6B operations per second are very usable by the CPU and don't take a massive performance hit by syncing. It's definitely not an article to say "i let a fragment shader do very simple math and it was very fast".
The key insight here that's easy to miss is that they never read data back from the GPU to the CPU. Most GPU-accelerated web demos lose half their gains to that round trip. By keeping the result on screen and handling the single-pixel cursor lookup with the CPU library instead, they sidestep the bottleneck entirely. The 400x gap over CPU isn't just about parallelism, it's about not fighting the architecture.
Cool tech, but the writing flags as AI.

Please don't harm your work like this. Let it speak for itself + add your authentic voice.
Also, the hardest part on the reader imo: Language that conveys an unearned sense of importance and emotion in appropriate places.
So great to see WebGL stuff featuring on the front page.
It was OpenGL that got me into graphics and games programming from a young age - NeHe's tuts in particular (anyone remember those?).
Are there similar introductory tuts for WebGL?
This is just AI slop explaining the very basics of what a pixel/fragment shader is. The usecase is not particularly useful. Doesn't belong on HN.

LLM slop. This account should be banned.
