What is PLY?
PLY (Polygon File Format), also known as Stanford Triangle Format, is a simple format for storing 3D mesh data. It supports vertices, faces, normals, and vertex colors. PLY files come in ASCII or binary format and are commonly produced by 3D scanners and photogrammetry software.
Why optimize PLY?
PLY files from 3D scanners and photogrammetry are often extremely large — millions of vertices with no compression. Optimization applies vertex welding, meshopt compression, and quantization to dramatically reduce file size while preserving all geometry detail and vertex colors.
What gets optimized?
Trice converts PLY to GLB with vertex welding, meshopt compression, quantization, and vertex reordering. Vertex colors are preserved. A default PBR material is created for models without color data.

Frequently asked questions
Yes. If your PLY file contains per-vertex color data, it will be transferred to the GLB output and preserved through the optimization process.
Substantial reduction. Meshopt compression typically reduces geometry data by 60-90%. Vertex welding removes duplicates. ASCII PLY files see the largest gains — often 90%+ reduction.
Yes. Both ASCII and binary (little-endian and big-endian) PLY formats are supported. Binary PLY files load faster during processing.
Yes. PLY files from Meshroom, RealityCapture, Polycam, CloudCompare, MeshLab, and other photogrammetry tools are all supported and benefit greatly from optimization.
