Crate ply2splat 

ply2splat

ply2splat is a high-performance library and CLI tool for converting Gaussian Splatting PLY files into a compact, optimized binary format suitable for real-time rendering.

Features

• Fast Parsing: Uses ply-rs for robust PLY parsing.
• Parallel Processing: Leverages rayon for multi-threaded conversion and sorting (when the parallel feature is enabled).
• Optimized Output: Produces a dense, memory-efficient binary format (32 bytes per splat).
• Sorting: Automatically sorts splats by importance (volume * opacity) and spatial position for deterministic rendering order.

Structs

PlyGaussian

Represents a raw Gaussian Splat read from a PLY file.

SplatPoint

Represents a processed Gaussian Splat ready for serialization. Layout is exactly 32 bytes packed: 3 floats, 3 floats, 4 u8, 4 u8.

Functions

convert

Converts PLY data bytes to SPLAT format bytes.

convert_file

Converts a PLY file to a SPLAT file.

load_ply

Loads a PLY file and parses it into a vector of PlyGaussian.

load_ply_from_bytes

Loads PLY data from a byte slice and parses it into a vector of PlyGaussian.

ply_to_splat

Converts a list of PlyGaussian structs into the optimized SplatPoint format.

save_splat

Saves a slice of SplatPoints to a file in a raw binary format.

splats_to_bytes

Converts a slice of SplatPoints to raw bytes.
