VR panorama, the full name is virtual reality panorama, that is, virtual reality panorama. It captures and displays the scene in 360 degrees without dead ends, making users feel as if they are in the scene. In China, there are mainly 720 cloud, Zhonggo, such as 720 cloud, Zhonggo, such as the platform to provide VR panoramic editing, display, and storage servicesIt is widely used in tourism, real estate, education, medical and other fields.
For example, in the field of real estate, customers can remotely understand the layout and decoration of the house through VR panoramic technology. In the exhibition promotion, users can experience the online and offline virtual or real exhibitions of enterprises, exhibition halls, and exhibitions around the world through VR panoramic technology
3D roaming is a technology that allows you to walk freely in a virtual environment. Let users walk and observe as they wish in a virtual environment. 3D roaming technology can be applied to games, animation, architectural design, and other fields. For example, in the field of games, players can freely explore and adventure in the virtual world through 3D roaming technologyIn the field of architectural design, designers can view the design effect in real time through 3D roaming technology, and make modifications and optimizations.
The difference between VR panorama and 3D roaming
Production costs
VR panorama is currently a fairly mature technology. In terms of production, panoramic photography is usually used to shoot composite panoramas in situ or to use 3D modeling to achieve virtual panoramas. The cost of the former is comparatively lower than that of the latter;
Of course, in terms of shooting, the cost of the equipment, technology and other reasons used by VR panoramic photographers is not the same. Therefore, when choosing to shoot VR panoramas, it is necessary to consider whether there are higher requirements for the picture and imaging effect, because this is also one of the important reasons for the rising cost.
Gamified 3D roaming is also a relatively mature technology, and if you need to achieve the exquisite effects of triple-A games, its production costs will skyrocket. This is because there is a lot of modeling and production of models, props, lights, object materials, etc. in the scene. This will increase the cost of personnel, management, time, etc. Some domestic enterprises with the goal of building a 3D metaverse have taken this technical route. Of course, there are also templating 3D models for virtual showrooms and other things, which can achieve fast and low-cost output.
respective advantages
VR Panorama: 1Short production cycle: advanced professional photography, generally shooting less than 20 scenes, shooting and production can be completed within 3-5 working days;The panoramic camera shoots with one click, no professional is required, and the shooting is simple and fast, and one person can shoot and produce quickly.
2.The picture is authentic and credible: It is suitable for the display and publicity of real shooting (such as: real estate, exhibition, enterprise, home decoration, etc.).
3.Convenient post-maintenance: VR panorama ** usually has its own web editing background, which is edited and managed by using a browserModification and update of content can be operated without professional technicians.
3D roaming. 1.High degree of freedom: users can walk and observe as they wish in the virtual environment
2.Strong spatial continuity: Compared with the VR panorama space, which is composed of scene points, the space for 3D roaming is complete.
Is there a technology that combines the respective advantages of VR panorama and 3D roaming?The answer is Yes!
Now, to realize the VR panoramic 3D roaming effect based on point cloud and depth map, it is to combine the point cloud data and depth map information in the three-dimensional space, and transform the two-dimensional VR panoramic image into a 3D scene with depth perception through specific algorithms and rendering techniques.
This 3D VR space roaming technology can directly generate a 3D space model, that is, a "3D house type", after combining the VR panorama with depth information and point cloud data, without modeling. At the same time, moving around the scene inherits the continuity of 3D walkthrough.
It is compatible with PLY point cloud data collected by 3D scanning equipment, PNG depth map data generated by AI or modeling software, and OBJ model data made by 3DMAX to meet the 3D digitization of real space and virtual space.
Through the way of "hot spots", a variety of different content types can be interacted with, and links to various contents such as audio, url, and navigation can be realized.
It can be said that the emergence of 3D space roaming technology has filled the huge gap between VR panorama and 3D roaming. It allows enterprises to choose their own technologies more flexibly, so as to achieve efficient and low-cost digital display and publicity.
In the traditional way of display and publicity, enterprises often need to invest a lot of manpower, material and financial resources to produce promotional materials, such as brochures, publicity, etc. These materials often need to be printed or recorded, which is not only costly, but also slow to update, and cannot meet the needs of rapid development of enterprises.
The emergence of 3D space roaming technology allows enterprises to choose their own technologies more flexibly, so as to achieve efficient and low-cost digital display and publicity. Through 3D space roaming technology, enterprises can easily create virtual exhibition halls, product displays, etc. with a high sense of realism, so that the audience can have a more intuitive and comprehensive understanding of the company's products and services.
