Now, as you can see, there are a lot of buttons here, but if we break it down into its. D file formats in this article. You can also jump to the most popular 3. D file formats directly. What is a 3. D File Format The basic purpose of a 3. D file format is to store information about 3. D models as plain text or binary data. In particular, they encode the 3. D models geometry, appearance, scene, and animations. The geometry of a model describes its shape. By appearance, we mean colors, textures, material type etc. The scene of a 3. D model includes the position of light sources, cameras, and peripheral objects. Finally, animation defines how a 3. D model moves. However, not all 3. D file formats store all of this data. D file formats such as STL store only the 3. D models geometry and ignores all other attributes. On the other hand, the format COLLADA stores everything. STL and COLLADA are just two of the many 3. D file formats that people use. We estimate that there are hundreds of 3. D file formats currently being used in the wild How Many 3. D File Formats are thereThe problem with 3. D file formats is that there are literally hundreds of them. Every CAD software manufacturer such as Auto. Desk and Blender has their own proprietary format which is optimized for their software. So if you use Auto. CAD, you get a DWG file. If you use Blender, you get a BLEND file. Proprietary 3. D File Formats Hinder Interoperability. However, the presence of so many proprietary file formats is a big problem. Suppose you use Auto. CAD which is an Auto. Desk product and your friend uses Blender. Suppose that you also want to share your 3. D model with your friend. This is not so easy. Your Auto. CAD software gives you a DWG file because it is the native Auto. CAD format. But your friends software, Blender, can only work with a BLEND file. This means that the two of you cannot work on the same 3. D model. Neutral 3. D File Formats Solve this Problem. To solve the problem of interoperability, neutral or open source formats were invented as intermediate formats for converting between two proprietary formats. Naturally, these formats have become hugely popular now. Two famous examples of neutral formats are STL with a. STL extension and COLLADA with a. DAE extension.   They are widely used to share models across CAD software. If you want to share your 3. D model, you convert the DWG file to a COLLADA file in a process called exporting and give your friend the COLLADA file. Your friend takes the COLLADA file and imports it into Blender, where the COLLADA file is converted to the native BLEND format. This way, you can continue to use different software and collaborate with others. Proprietary vs. neutral is one of the most important dichotomies in the world of 3. D file formats. Nowadays, most 3. D modeling software supports reading and writing popular neutral formats. In addition, most software also support reading and writing to a subset of proprietary formats that are so popular that they cannot be ignored. We will discuss 8 such 3. D file formats in this article. Here is the list, where the 3. D file formats are marked with their type. But before we discuss each these formats in detail, we will first take a look at the general features of a 3. D file format and discuss the important things you should keep in mind when selecting a format for your project. General Features of 3. D File Formats. As we discussed earlier, the general features of a 3. D file format are Encoding geometry of the 3. D model. Storing appearance of the 3. D model. Saving scene information. Encoding animations. D File Formats Encoding Geometry of the 3. D Model. Every 3. D model has a unique geometry and the capability of encoding this geometry can be considered to be the most basic feature of a 3. D file format. Every 3. D file format supports this  otherwise, they wouldnt be considered 3. D file formats. There are three distinct ways of encoding surface geometry, each with their corresponding strengths and weaknesses. They are called approximate mesh, precise mesh and constructive solid geometry CSG. D File Format Geometry The Approximate Mesh. In this encoding, the surface of a 3. D model is first covered with a mesh of tiny imaginary polygons. Triangles are most commonly used shape. The vertices of the covering triangles and the outward normal vector to the triangles are stored in the file. This represents the surface geometry of the target model. The process of covering a surface with non overlapping geometric shapes is also known as tessellation. Hence these file formats are also called tessellated formats. The triangles approximate the smooth geometry of the surface. Hence this is an approximate format. The approximation gets better as the triangles get smaller. However, the smaller the triangles, the larger the number of triangles you need to tile the surface. This implies that the file needs to store a larger number of vertices and normal vectors. Thus better approximations come at the cost of increasing file size. Approximate or tessellated formats are best used in situations where you dont need ultrafine resolutions of the 3. D model. A good example is 3. D printing. 3. D printers cannot print beyond a certain resolution and therefore, this type of 3. D printing file formats are perfect for the job. In fact, the most popular 3. D printing file format STL indeed belongs to this class of file formats. D File Format Geometry 2 The Precise Mesh. There are, of course, situations where an approximate encoding of the 3. D model is not enough and one needs precise encoding of the surface geometry. For example, when constructing the body of an airplane, in particular the round hull, a discrete polygonal mesh wont work. Although the model might look good at small resolutions,  the flat faces and sharp corners will become apparent up close. Precise file formats get around this problem by using Non Uniform Rational B Spline patches or NURBS instead of polygons. These parametric surfaces are made up of a small number of weighted control points and a set of parameters called knots. From knots, a surface can be computed mathematically by smoothly interpolating over the control points. These surfaces look smooth in any scale and can replicate the surface geometry of a small part of a 3. D model in exact detail. However, theres always a trade off. While the precise mesh is exact at any resolution, they render slower and should be avoided in applications where speedy rendering is important. D File Format Geometry 3 Constructive Solid Geometry aka CSGFinally, theres yet another type of file format that does not involve meshes at all. In this format, 3. D shapes are built by performing boolean operations addition or subtraction of primitive shapes like cubes, spheres etc.
