Hey everyone, have you ever wondered what kind of file 3D viewer uses? Well, let's break it down! When it comes to 3D modeling and design, there are several file formats that are commonly used for viewing and sharing 3D models. One of the most popular file formats for 3D viewing is the .OBJ file format. This format is widely supported and can be easily viewed in many 3D viewer applications. Another common file format is .STL, which is often used for 3D printing and can also be easily viewed in 3D viewer software. Additionally, .FBX and .DAE are also popular file formats for 3D modeling and can be viewed in various 3D viewer programs. These file formats are commonly used because they store both the geometry and material information of 3D models, making them compatible with most 3D viewer applications. So, next time you're working with 3D models and wondering what file format to use, keep in mind that .OBJ, .STL, .FBX, and .DAE are some of the most commonly supported formats for 3D viewer software. Happy modeling!
