Convert PMX to GLB for free

PMX is a model file format used in Japanese MMD (MikuMikuDance) software, the full name is Polygon Model eXtended. The PMX format has better extensibility and functionality than the original PMF (Polygon Movie Format) and PMD (Polygon Model Data) formats of MMD. The PMX format file contains all the information of the 3D model, including the model's mesh, materials, bones, weights, animation data, etc. In MMD, users can create their own 3D characters and make various animations by importing model files in PMX format. The PMX format supports more types of materials, including specular reflection, transparency, glow and other effects, as well as a variety of bone types and animation interpolation methods, which can more flexibly express various movements and postures.

GLB is a binary file format representation of 3D models saved in GL Transfer Format (glTF). Information about 3D models such as node hierarchy, cameras, materials, animations, and meshes in binary format. This binary format stores glTF assets (JSON, .bin, and images) in binary blobs. It also avoids the problem of increased file size that occurs in the case of glTF. The GLB file format brings compact file size, fast loading, full 3D scene representation, and extensibility for further development. The format uses model/gltf-binary as the MIME type.
