I know that GLTF is normally used for triangle mesh representations of 3D geometry, but my work would benefit from having some additional representations of 3D data. I was hoping to write an extension to GLTF file format that allows for use of signed distance values on a regular 3D grid to define geometry, but I have some questions.
- Should I extend the definition of “mesh” to include this volumetric representation or should I create a new top level element?
- Is GLTF explicitly for triangle mesh surface representations. By that I mean, should I not bother writing this extension to the file type?
