Description

I have a 17GB Gaussian Splatting PLY file. When I use splat-transform to convert this PLY file into either .compressed.ply or .sog format, errors occur. My computer has 64GB of RAM. How can I resolve this error?

Research direction

Start with the splat-transform CLI and reproduce the failure while converting the reported 17GB PLY file to .compressed.ply and .sog. Trace where “Custom comparefn not supported for huge TypedArrays” is raised; the work is done when both conversions complete successfully for this input.
