With more and more companies entering the 3D space and continual advancements in technology such as , AR (Augmented Reality), game design, VFX and the evolution of long-standing CAD (Computer Aided Design) applications, it is only natural that new file types of surfaces to handle these different capabilities.
Generally speaking, you’ll encounter two types of formats: polygonal geometric data and boundary representation (BREP) depending on where the geometry was originally constructed. CAD applications can output both methods of storing geometric data. To preserve the higher-level geometric information in the CAD world, you’ll encounter a separate set of file formats which also contain standard polygonal data used in 3D printing and in gaming applications. Both types of geometric definition can be complex and result in large file-sizes.
Here are some of the most common 3D file types you may encounter and when you should consider using them.
