The realization of the system requires the construction of a 3D model, which is an essential element for the establishment of the whole virtual reality scene. The virtual reality technology is utilized to simulate things in the real world in a virtual digital space, integrates multiple subjects such as digital image processing, computer graphics, multimedia technology, sensing and measuring technology, simulation and artificial intelligence and the like, and establishes a vivid, virtual and interactive three-dimensional space environment for people. Only a fine and vivid model can construct a scene which can make the user personally on the scene. However, if the model and the scene are too fine, the data size is too large, and a disaster is brought to the virtual reality application system. The data volume is as small as possible under the condition that the quality of the model is ensured in the modeling work of the virtual reality.
The specific manufacturing process of the 3D model is as follows:
1) and placing a light and a camera, wherein the light production is the basis for reconstructing an object model in the three-dimensional production, and other work flows depend on the object model. After the scene is set, the needed model can be created in the scene. Objects can also be transformed into a variety of editable surface types, starting from different 3D geometry primitive volumes, and then further modeled by stretching vertices and using other tools.
2) And using the material, after the model is established, designing the material by using a material editor, and endowing the designed material to the model in the scene, so that the established model has real texture.
3) The key components play a crucial role in representing scene atmosphere and the like. After the material is manufactured, the lamp and the camera can be placed in the scene, so that the material is really displayed on the surface of the model,
4) setting scene animation, if the created scene needs to be shown in an animation mode, using the animation setting function in 3dsMax to create the animation effect of the model in the scene.
And rendering the scene, wherein rendering refers to calculating the settings of environments such as brightness, shadow, background, atmosphere and the like according to the specified material and the lighting of the scene, so as to display the geometric solids created in the scene in an materialized manner.
Note that:
1) the unit and the proportion, the size and the unit are required to be set before modeling, the unit setting in the same scene must be the same, and the proportion of the model and the model quality inspection is required to be correct.
2) The axes and the faces are counted, and all the character models stand at the original points. Without specific requirement, the center of the object must be the axis. The surface number controls that a single object is normally controlled below 1000 surfaces, the whole screen is controlled below 7500 surfaces, and all objects are not more than 20000 triangular surfaces.
3) Texture maps, where not all textures are supported by Unity3D software in 3dMax, but only Standard and Multi/Sub-Objiect are supported by Unity3d software.
4) The format of the map file, jpg without channels in the original map, 32 bits of tga or png with channels, the maximum size of which exceeds 2048, the size of the map file must be 2 to the power of N (8, 16, 32, 64, 128, 256, 512, 1024) and the maximum map size cannot exceed 4096x4096, and the size can be adjusted within these ranges in special cases.
The development of project functions is developed by adopting a Unity3D engine platform, and C # language coding is adopted according to the detailed design scheme of the project, so that objects and UI interfaces can interact and move, and the development is carried out according to the coding standard and specification of the augmented reality technology.
In the project, the handle is detected through rays, so that movement in a scene and handle interaction are realized. The ground movable area is controlled by the Navmash technology. In order to reduce the memory occupation and optimize the experience effect, a shielding rejection technology and an anti-aliasing technology are used, the edge smoothness is realized, the aliasing is eliminated, and the damage of image folding is resisted. If the loading of the resources is time-consuming, a synchronous method is adopted to generate a pause phenomenon, so that the scene switching is carried out in the system by an asynchronous loading technology, the asynchronous loading speed is high, and the asynchronous loading is unrelated to the main thread. Two triggering modes are used for interaction in the system, one is a ray, and the other is a trigger. The UI is selected to be larger in the main scene, the ray collision is used far, the pressing plate is smaller in the pressing plate putting operation, and the trigger can simulate the user to rotate the pressing plate by hand in a real environment.
