Read the element.

One storage graph writes four typed lanes, then the material fetches individual elements by index. The same contract runs through the WebGPU backend and the WebGL2 fallback.

Four buffers hold float, vec2, vec3, and vec4 elements. The bars are colored by indexed storage reads, not CPU-generated pixels.

The paired renderer views could not start.

Each row is a storage lane · the two panes follow the pinned official WebGPU/WebGL backend comparison.
