If you work with 3D models, you may have come across the .OBJ file format. This file format is commonly used for storing 3D object data, including geometry, texture, and material information. To view and interact with .OBJ files, you can use a .OBJ viewer, which allows you to explore 3D models without the need for expensive 3D design software. With a .OBJ viewer, you can rotate, zoom, and pan around the 3D model to inspect it from different angles. This can be particularly useful for architects, designers, and artists who want to showcase their 3D designs to clients or colleagues. The .OBJ viewer also enables you to apply different materials and textures to the 3D model, giving you a better understanding of how the final design will look. Additionally, with .OBJ viewer, you can examine the structure and layout of the 3D model, making it easier to identify any potential issues or areas for improvement. Some .OBJ viewers even support animations, allowing you to visualize how the 3D model moves and behaves. Overall, .OBJ viewer provides a user-friendly way to interact with 3D models, making it a valuable tool for anyone working in 3D design and visualization.
