OBJ coordinates have no units, but OBJ files can contain scale information in a human-readable comment line.īlender, Vectary, Autodesk 3ds Max, Autodesk Maya, Modo, Paint 3D Vertices are stored in a counter-clockwise order by default, making explicit declaration of face normals unnecessary. The OBJ file format is a simple data format that represents 3D geometry alone - namely, the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of vertices, and texture vertices.
The file format is open and has been adopted by other 3D graphics application vendors. obj) is a geometry definition file format first developed by Wavefront Technologies for its Advanced Visualizer animation package.
GLB file format results in compact file sizes, fast loading, complete 3D scene representation, and extensibility for further development. It also avoids the issue of an increase in file size, which happens in glTF. This binary format stores the glTF asset (JSON. Information about 3D models such as node hierarchy, cameras, materials, animations, and meshes in binary format. GLB is the binary file format representation of 3D models saved in the GL Transmission Format (glTF).
