@etpinard @monfera can you please do npm publish here or grant me permission npm owner add dfcreative gl-pointcloud2d

[etpinard]

I don't have publish rights for gl-pointcloud2d unfortunately. So it's up to @monfera (no rush though 😄 )

@dfcreative @etpinard thanks for the note, I just added both of you, tell me if it doesn't work out.

Have we a codepen similar to this that shows the (by client requirement, low) initialization and update latency? I just re-checked it, it used to be 25-30FPS but now only around half of that, not sure if it's due to possibly slower browser / OS versions. We must be able to do a redraw cycle in <100ms so we're still good; I'm sure the new thing is as good or is an improvement.

[etpinard]

@monfera are you suggesting that bumping the glslify version slowed down pointcloud?

[monfera]

@etpinard no, because that wouldn't have changed the shader code; there might have been some general or WebGL specific slowdown in browsers. Fixes for things like Meltdown, Spectre or bugs may influence performance.

Ah nice. Good to know. Thanks for pointing this out!
