![]() ![]() ![]() ![]() In the play, or run-time, mode the user interacts with the prepared scene: moves the 3D objects along the scene, changes materials or lights (e.g., to see effects of the changing environment). Once the scene is ready, the application can use these prepared assets (called prefabs) in the run-time. Preparation may incorporate proper locating of the light sources, positioning of the 3D objects, applying textures to them for superior rendering and immersive experience, and so on. For automotive design review apps, it could be the car interior elements coming from CAD systems. While in the edit mode, the user or developer provides 3D objects (called ‘assets’) to be prepared and integrated (‘baked’) into the Unity scene.įor instance, for AR/VR apps for some training simulations, these assets can include 3D models of the equipment and tools. Virtual environments in industrial workflows What is Unity edit mode? So, how to close that gap and bring your 3D CAD data into the Unity game world?īefore we dive into that, let’s review two key modes the Unity operates in - edit and play (or run-time), and two distinct 3D data representations - mesh and B-Rep. Game engines are utilized for building realistic virtual environments in design and industrial workflows, ranging from marketing materials creation to remote maintenance performance, from customer-oriented product configurators to immersive collaborative design reviews.Īutomakers such as Volkswagen, Toyota, BMW bring their design reviews into the Unity-powered scenes for more realistic visual feedback and immersive user experience.ĪEC/BIM users can create augmented reality (AR) solutions with Unity Reflect to bring tablets with Unity onto construction site to preview future buildings in the actual landscape.ģD app developers are captivated by visualization and AR/VR capabilities offered by the game engines and look for ways to work with their engineering CAD data with the help of these platforms. Game engines adoption has moved beyond the game world for quite some time, and such giants as Unity and Epic Games now move significant focus on catering to the needs of engineering and manufacturing. Hopefully, developers from adjacent universes of Unreal Engine by Epic Games and CryEngine by CryTek (and possibly others) may also find this post useful. This post will be most helpful for software developers who plan to or are already developing their 3D apps on top of Unity and face challenges to work efficiently with 3D CAD data. We will specifically focus on unique CAD Exchanger SDK features you could leverage to build your CAD-enabled apps. We will try to summarize available options and give particular recommendations. If you have been exploring the ways to bring your CAD data into the Unity, this blog post could possibly help you navigate your way.

OBJ coordinates have no units, but OBJ files can contain scale information in a human-readable comment line. Vertices are stored in a counter-clockwise order by default, making explicit declaration of face normals unnecessary. The OBJ file format is a simple data format that represents 3D geometry alone - namely, the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of vertices, and texture vertices. FBX is also part of Autodesk Gameware, a series of video game middleware. It is used to provide interoperability between digital content creation applications. The file format is open and has been adopted by other 3D graphics application vendors.įBX (Filmbox) is a proprietary file format (.fbx) developed by Kaydara and owned by Autodesk since 2006. obj) is a geometry definition file format first developed by Wavefront Technologies for its Advanced Visualizer animation package. ![]()
