Definitions
- the invention relates to the field of data processing, in particular to the processing and generation of image data, and in particular to a method for three-dimensional visualization of real estate objects based on virtual reality technologies.
- a system for designing objects in a virtual reality environment in real time is known (System for designing objects in a virtual reality environment in real time: patent RU2656584, Russian Federation, application RU2017108366, application 14.03.2017, publ. 05.06.2018).
- the system contains at least one display device configured to: display at least one three-dimensional image of an object in real time, track the movement of a marker, receive data from a computing device, receive data from a positioning device, as well as at least one positioning device, configured to: measure the position and orientation of at least one limb of the user, update the position of the object in the virtual reality environment and display it on the display device, receive data from the computing device.
- the method for designing objects in a virtual reality environment, describing the operation of the above system was taken as a prototype.
- the technical problem is the need to develop a method for three-dimensional visualization of real estate objects based on virtual reality technologies, devoid of the above disadvantages.
- the technical result is to increase the accuracy of three-dimensional visualization of real estate objects.
- the technical result is achieved by the fact that in the method of three-dimensional visualization of real estate objects based on virtual reality technologies, during which information about the object is received, the object is analyzed, a virtual space is formed, according to the invention, during the analysis of the object, the information necessary to create 3D models is filtered, then on at the stage of virtual space formation, preparatory drawings of the object are formed and loaded into a 3D package, key image references are determined, first high-poly object geometry is created, and then low-poly, then a map of UV coordinates is created, raster or procedural textures are projected onto the surface of a three-dimensional object in accordance with the map of UV coordinates, export a 3D model with low-poly geometry and texture maps, set up assets, including setting up a UV channel for a shadow map, setting up object collisions and setting up a shader, then create dynamic objects, generate a house adjoining territory, create spherical panoramas to create a view from the window, set up lighting, arrange reflection capture, arrange assets, assign
- the concept of virtual space is taken to mean a set of virtual reality objects.
- object means a real estate object.
- the inventive method is carried out as follows.
- information about the real estate object is received, which includes an image of all the premises of the object from various angles and, if necessary, a description of the object. Then the information is analyzed and filtered in order to select the data necessary for the creation of 3D models and further visualization. Then preparatory drawings are formed, including only the contours of the walls and the location of windows and doors, which are loaded into the 3D package at the stage of wall modeling. Then the key references of images and / or drawings are determined, which specialists are guided by at the next stages of asset creation. Next, the geometry of the high-poly object is created, then the low-poly.
- the high-poly model contains all the details of the object, which are later transferred (projected) to the low-poly model and recorded in the normal map.
- a UV scan is created in accordance with accepted standards.
- raster or procedural textures are projected onto the surface of a three-dimensional object in accordance with the UV-coordinate map.
- the 3D model is exported, which includes low-poly geometry and texture maps.
- the asset setup stage is carried out, which includes setting up the UV channel for the TeHe map (lightmap), setting up object collisions and setting up the shader.
- TeHefi Lightmap maps
- Prepared assets (furniture, lamps, decorative elements, etc.) are placed around the room in accordance with the plans and the chosen design.
- shaders are assigned to the surface. Building models that are visible from windows and balconies are added to the scene, shadow maps and shaders are configured for them, teleportation points are placed according to the level (apartment), their coordinates are transmitted to the remote control interface.
