Virtual reality has become more and more important and successful in everyday life over the last few years. In this article you will learn what exactly "VR" is and where it is used.
The term "VR" stands for "Virtual Reality". Special glasses are required for this. These glasses can display computer-generated content by means of a 3D engine and adapt to human vision. Thus, VR glasses mainly address the optical and acoustic senses and can thus create an extremely believable experience. They are controlled by head movements or by additional controllers.
We are an independent developer studio. In the studio we deal with the development of entertainment software of various types. Our portfolio ranges from business apps, marketing solutions to educational applications. Feel free to contact us at any time.
The VR glasses are often used for computer games. This makes the gaming experience something special. But VR can also be used as a tool for visualizations. This opens up a wide range of possible applications. For example, in simulation, sports, film and animation. VR is therefore not only suitable for gaming projects.
No. The basic benefit is the display of 3D content on the glasses. Separate VR apps have to be developed for this. However, these apps can also visualize different industrial use cases, for example. For example, large machines no longer have to be transported at great expense, since unlimited projection surfaces are available in 3D space. Furthermore, interactive operating instructions can be produced or complicated machines and their core benefits can be presented in a simplified way. This technology can also be used to visualize entire construction projects before they are actually built. Planning errors can be avoided and detected in advance. Meanwhile, some amusement parks are building their own VR experiences.
VR is just as suitable for helping people, however. For example, VR goggles can be used to specifically trigger emotions. In this way, fears can be overcome in virtual worlds. In the studio, we have developed our own VR app for this purpose, which helps people to overcome their fears. In addition, VR can also be used in education. Through visually appealing learning games, any topics can be explained more easily. In our experience, the learning content is transferred much faster and retained longer in the memory. The age of the learner does not matter.
With the help of photorealistic textures and realistic surface shaders, a very high degree of realism can be achieved. This becomes clear in one of our customer projects, for example. There, even entire building complexes were visualized with the help of VR. The building complexes could be virtually "entered" and visited at any time thanks to VR. The experiences in VR are therefore very immersive and therefore remain in the memory. They are very different from conventional media.
There are many ways to implement a VR project. All real objects can be created in 3D programs and displayed in VR. Modeling programs are often used for this purpose. Blender, 3DsMax or Maya are among the most popular tools. After completion, the 3D models are merged in a 3D engine and provided with different functionalities by means of program code. Afterwards the project can be exported for the glasses. When projects have been exported, they can be "entered" with the VR glasses.
There are currently many different VR goggles on the market. They differ from each other in price, quality and functionality. The most commonly used VR glasses are the Oculus Rift, HTC Vive and Playstation VR. Alternatively, there are special frames for smartphones, with which VR apps can be displayed on the user's own cell phone. These two options offer a similar media experience. Some VR projects require powerful computers, while other projects get by with less power.
