What are some common 3D standards and best practices in modeling?

Common 3D standards include key file formats like OBJ, FBX, and GLB, while best practices focus on topology optimization, polygon efficiency, and format compatibility. 3D standards ensure cross-software and platform compatibility. OBJ is ideal for static models due to its simplicity; FBX supports animations and materials, widely used in gaming; GLB is compact, preferred for web/AR/VR. Best practices involve: 1) Quad-dominant topology (minimize triangles to avoid rendering issues). 2) Matching polygon count to use case (low-poly for real-time apps, high-poly for detailed renders). 3) Clean UV mapping for texture accuracy. To excel, balance detail with efficiency: start with low-poly, refine topology, and select formats based on needs (e.g., FBX for animations, GLB for web).
