VR + BIM: How can the two technologies be combined efficiently?

Together, virtual things are presented to you in an enhanced way. What can 2VR do for us? For designers, the most direct use is to present design results to customers and interpret their intentions faster and better. Although Revit is much better than 2D design software in this area, but compared to the following diagram, you will find that the effect of 3DMax makes you start to doubt and can not stand Revit!! Revit hotel room design 3DMAX hotel room design If you want to consult with consultants or customers Demonstrating your own design, which effect is better, it goes without saying. As you can see in a BIM + VR introduction article, VR not only lets people see the design effect, but also makes people feel your design. (WithVR,architecture scantransmitnotjustwhatabuildingwilllooklike,butalsowhatitwillfeellike.) Solution Passing When we say shorten the construction period, we first think about reducing the design + construction time. In fact, in most projects, the design time has no compression elasticity, and ultimately you want to sacrifice design. The health of the division is also at the expense of the quality of the design. There are too many uncontrollable factors for the construction time, such as construction disturbances in Beijing + major government meetings + hazy weather + holidays... enough time is needed to prepare for accidents. In government projects or complex projects, a lot of time is wasted on the conceptual design or program design stage. Designers report the plans to the owners (or government departments) over and over again to sell their ideas, and modify the plans over and over again to cater to the owners’ dreams. Various novel ideas; many final decision makers are non-professionals, or not professional enough. The VR demo can definitely make it easier for decision makers to understand your intentions, so that the solution can pass faster. Less than one plan meeting, one less modification, saving time with you to change a few doors and windows, not the same language. When the product of the owner’s product is not listed in advance, it can be used to promote future results to potential customers. A BIM video of a government co-tenancy project was seen at the Hong Kong BIM Association. The room status of the owner when the house was collected and how it will be renovated in the future were displayed to the public with the Revit model. With VR you can simply go for a walk in your favorite apartment or feel your finished store. Of course, based on the software of the game engine, you can easily carry out analysis of the flow inside the project. This is absolutely beneficial to hospitals, shopping malls and public transport facilities. In short, VR helps BIM improve the workflow and let customers see unfinished buildings. 3 Existing VR uses statistical data and successful cases to look at a survey conducted by CGarchitect. The results show that VR+BIM Europe is at the leading edge and is basically twice the number of applications in the United States (I am also very surprised, I don't know why). And VR+BIM application has made great progress in 2015 and 2016. It is rare to see successful domestic VR+BIM cases. The Shanghai Disney project should be a domestic design institute to complete the BIM model, and the VR part should be completed by a foreign team. The Disney team is based on their own powerful entertainment + game genes, doing Show in the model, or in the 3D virtual reality room (VRCave) for project discussion. Picture from 2014 AIABIM winning project WDIShanghai-EnchantedStorybrookCastle Shanghai Center The Shanghai Center project that saw Stingray's promotion video did not do VR when I knew the project. It should be done recently. Based on the project's Revit model, a lot of processing was done in 3DMAX, and the facade and interior decoration were revealed by Stingray. The picture is taken from the video of Autodesk Stingray. The United States NPS (National Park Service) of the Arizona Ship This project is to commemorate the Arizona sunk during the Battle of Pearl Harbor in World War II. It scanned the sunken area of ​​the seabed to form a point cloud model, and virtually reproduced the battleship in the memorial hall. The status quo on the sea bottom. No need to salvage warships, visitors do not need to dive underwater, you can feel the sinking warships, more shocking than the salvage exhibition! Picture from NPS website NavigatingtheUSSArizona4 Hardware and software situation Computer VR will configure the computer (especially the graphics card and Memory) and other high requirements, if your computer is running Revit is very slow, do not consider using it to run large VR software. By the way Tucao about design + construction units, the network is full, computer cards, blueprints like old cow carts, all day urged everyone to save costs and print less, as if the engineer's time is not cost ah! Do not respect the engineer's innovative labor, Use an engineer as a coolie. Mainstream VR devices for VR devices are basically head-mounted displays (HMDS) such as HTCVive, Microsoft HoloLens, Samsung GearVR, FacebookOculusRift, and Google Cardboard. These devices are not specifically designed for the construction industry, so there are some problems with their use. Software I now look at the workflow is Revit-3D Max-Stingray, mainly because the BIM model is built in Revit. Revit exports FBX format files and adds special effects to Stingray after 3DMax processing (material, Polygon). 5 Application Prospects VR+BIM applications are based on game engines and require a considerable amount of knowledge. This poses a great challenge to engineers and makes it difficult to balance design with VR. It is estimated that a few high-end projects will be available, so this may be like a model-making company, relying on professional outsourcing companies. However, after all, it can connect the construction industry and investment circles. It is hoped that VR+BIM will be a pool of stagnant water, and the construction market where low-price competition is prevalent will stir up waves of confusion. And when you look at VRPorn, if you are hit by someone, you can quickly switch the viewpoint and pretend to see the interior effect of the room! As the author said, for designers, the most direct use of VR is to show the design results to Clients interpret their intentions faster and better. 87 Jun hopes that VR technology will inject more vitality into BIM and benefit more users and practitioners. "> ▼ VR + BIM: How can the two technologies be combined efficiently? From Baidu VR BIM (Building Information Modeling) refers to the building information model. It is to describe computer-aided design that is based on three-dimensional graphics, object orientation, and architecture. So what combination of BIM technology and VR can bring? The two major selling points of BIM are the enhanced 3D visual effects + the creation of virtual models. These two selling points apply to the extreme demand of VR. Of course, if you're still confused about why BIM? And if it's BIM, or if you've come up with a construction plan, VR+BIM is definitely not your food! Picture from CGarchitect I have been collecting data for the past few months and I'm still hesitating to use VR on the project. The reason for hesitation is that, as an engineer, whether to continue to insist on structural design + mechanics analysis, or to use BIM PM as its own development goal, after all, VR needs too much research, and it is difficult to quickly grasp the flexible use of VR alone; Another very real question is whether the owner or project is willing to pay for it? 1 What is the difference between VR, VR and AR, MR? No obscure technical terms are limited to my own understanding: VR (Virtual Reality) is about virtual (or future, non-realistic) things that are immersed in, head-mounted devices displayed in front of you. AR (Augmented Reality) and MR (Mixed Reality) are easily understood by literal meaning: AR is to show you what is in reality and enhance it. MR is about to merge VR and AR, and to present virtual things to you in an enhanced way. 2 What can VR do for us?

As you can see in a BIM + VR introduction article, VR not only lets people see the design effect, but also makes people feel your design. (With VR, architects can transmit not just what a building will look like, but also what it will feel like. ) The plan passed quickly When we say that we need to shorten the construction period, we first think about reducing the design and construction time. In fact, in most projects, the design time has no compression flexibility. In the end, do you want to sacrifice the health of the designer or sacrifice the quality of the design?
