Typescript writer & picovdb file utils

[ablexCarey]

This is a really neat project, thanks for sharing.

Have you thought about adding read from the GPU and write a picovdb file or append the data as a new time slice to an existing file?

I'm looking for a solution to recording, displaying and updating a sparse time varying dataset using a web UI. An evolving volumetric heat map.

I'm thinking about updating the GPU data through the interaction then wanting to save it and reload it to resume updating it. Or perhaps creating series of picovdb files from separate interactions then combining them. Creating an increasing long time series to use in analysis or animation.

Your project is the closest Ive found to a purely web native pipeline that looks like it could be used to achieve this.

Obviously its early days and the format is in flux, but keen to know if this is something you would consider or is even a fit to what you are building?

Thanks! I'm working on adding support for different types of volumes. Also looking to support animations (I think this would be simply iterating through the different model grids based on a frame count). I've thought about adding edits to the data structure in either typescript or zig (compiled to wasm). The structure is read-only but partial edits and then regenerating should be cheap. Not sure if there would be advantages to doing this on the GPU side or not but something I would be keen to explore too.

If you have more details about the data flow I'd definitely use it as a use case to support. Are you able to model the updates with OpenVDB or other libraries?
