the distributed rendering server unit is used for deploying a plurality of servers and enabling the rendering unit to complete rendering;
a browsing key is arranged on the browsing unit, and when the browsing key is pressed down, the current three-dimensional scene is locked; and the method is also used for browsing the locked three-dimensional scene in 360 degrees in an all-round way.
In specific implementation, the corresponding floor plan can be selected from the existing floor plans in the database. The user can draw the user type desired by the user on the grid graph and move the mouse on the grid graph, so that new lines can be added. The position and the length of the line can be changed by selecting the line to drag. The home industry service system based on the 3D cloud design can be set as a computer end or a mobile end, and when the home industry service system is developed into the mobile end, a browser based on the mobile end needs to be developed and used for browsing three-dimensional scenes.
According to the home industry service system, a user can draw or select a home model in the home industry service system to carry out home decoration design, the design flow is simplified, what you see is what you get is realized, and the user participation and the user experience are improved. The conversion among various model formats in the furniture model is also provided, and the problem that the model made in a certain system cannot be directly used in other systems due to the fact that the direct format materials of various model tools/3D engine software systems are not compatible with each other and can be used only after being manually reprocessed according to the specific format and material of a target system is solved.
In a three-dimensional scene, a furniture model can be dragged at will and placed at a desired position. When the model is dragged, the furniture model to be dragged is selected, and after the furniture model is selected, the mouse can be dragged to move the furniture model to a proper position. The house type drawing unit is also used for dragging the furniture model in the three-dimensional scene to change the position or the direction of the furniture model in the three-dimensional scene. The furniture model also comprises an aperture, and when the furniture model is dragged in the three-dimensional scene and is selected, the aperture of the furniture model is green; and when the furniture model is not selected, hiding the aperture of the furniture model. When the position or the direction of the furniture model in the three-dimensional scene is changed, the color of the aperture is different. For example, the aperture may appear light green when changing position and green when changing direction. The user can conveniently and intuitively know the current executable operation through displaying different colors.
In addition, a lamp model can be added in the three-dimensional scene, and the light rendering effect can be experienced. Meanwhile, the brightness of the light can be changed. The lamp brightness of the lamp can be changed by selecting the lamp model needing to change the lamp brightness.
The browsing unit is further used for generating a VR scene from the locked three-dimensional scene, and therefore the user can roam in the VR scene by wearing VR glasses. And the browsing unit is also used for amplifying, reducing or moving the locked three-dimensional scene up, down, left and right through a mouse. After the room is designed, the user can browse the works in the three-dimensional scene. In order to facilitate browsing of a user, a scene lock function is specially set. The current scenario can be locked, i.e., the model can no longer be selected for change. At the moment, a user can directly click any position to drag a scene by a mouse, the scene angle is changed, the scene is enlarged/reduced by rolling the mouse, and the current scene is browsed in a 360-degree all-round mode. Meanwhile, the effects of zooming in/out, moving up, down, left and right scenes can be realized.
In the process of using the furniture model, the direct format and material of each model tool/3D engine software system are incompatible, so that the model made in a certain system cannot be directly used in other systems, and can be used only after being manually reprocessed according to the special format and material of the target system. For this purpose, the selection unit is also used for inputting the furniture model and for performing a conversion between the respective model formats in the furniture model.
The conversion method between the model formats mainly comprises three steps:
A. and the model is manufactured, so that the model processing cost is reduced. And (3) standardizing the model: ungrouping, collapsing, centering, frying, re-centering, rotating, naming consistency, etc.
B. And (3) model processing, namely performing collapse, inverse subdivision and reasonable model compression by using a plane algorithm on the model. And drilling model material information, acquiring associated material information through a reflection mechanism, and obtaining model grids everywhere.
C. Engines use, translating textures in a variety of engines.
The method comprises the following specific steps:
standardizing the imported furniture model to obtain material information of the standardized furniture model;
converting the furniture model into a preset general model format;
importing a target engine and a target model texture corresponding to a target model format;
judging whether the material information in the furniture model in the universal model format is matched with the texture of the target model;
if so, covering the texture of the matched target model with the material information of the matched furniture model;
and after covering, constructing a rendering environment for rendering to obtain the furniture model in the target model format.
The acquiring of the material information of the standardized furniture model includes:
analyzing the mapping and the material of the standardized furniture model;
identifying and resolving a hierarchy of the material;
and recording the material of each level in the furniture model.
The selection unit is used for carrying out format conversion among MAX, UE4, UNITY and BLEND in the furniture model. The method can solve the problem of model conversion without manual processing, and provides model format conversion support for a plurality of 3D engines.
The design is accomplished the scene, and the user can render the function of rendering of using approximate real effect, will design the scene and render into effect picture or panorama effect picture and generate the VR scene simultaneously, wears VR glasses and just can get into the design of the experience oneself of invading formula.
When effect graph rendering is carried out, the system provides the distributed server deployment capacity, and an infinite number of servers can be added to the distributed rendering server unit to improve the rendering speed and the concurrency quantity, and the speed and the concurrency quantity are only limited by the network speed.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
