Description

Read and Write '.gltf' and '.glb' Files.

The 'glTF' file format is used to describe 3D models. This package provides read and write functions to work with it.

rgl2gltf: Read and write .gltf and .glb files

This R package contains functions to read, write and display .gltf and .glb files containing 3D models, following the official spec at khronos.org

  • It also contains functions to convert rgl scenes and mesh3d objects to and from glTF objects.

It is still in active development. Please add issues or pull requests if something important to you is missing.
