Convert COLLADA to GLB for free

COLLADA is an XML-based digital asset exchange solution for interactive 3D applications, allowing 3D creation applications to freely exchange digital assets without losing information - enabling a powerful toolchain pipeline combining multiple DCC and 3D processing software packages. Its unique interactive mode provides a comprehensive visual compilation. COLLADA FX supports the creation and encapsulation of shaders using OpenGL ES shading language, enabling first-class 3D creation tools to effectively collaborate in creating OpenGL / OpenGL ES applications and assets.

COLLADA is an open standard, originally used for 3D software data exchange, initiated by SCEA, and now supported by many well-known manufacturers such as Autodesk and XSI. COLLADA can be used not only for exchanging data between modeling tools, but also as a scene description language for small-scale real-time rendering. Because COLLADA DOM has rich content for representing various elements in the scene, from polygonal geometry to cameras, we can use the COLLADA DOM library to read and process scene files. The programming method of COLLADA DOM is similar to COM.

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.
