Embodiment 1

[0045] figure 1 It is a flow chart of a scene generation method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of generating a VR scene according to a scene in a rendering engine. The method can be executed by a scene generation device, and the device can be realized by software and / or hardware. see figure 1 , the scenario generation method provided in this embodiment includes:

[0046] S110. Obtain a simple model for building a VR scene according to the fine model in the original scene.

[0047] Among them, the simple model can be generated by removing a set number of vertices from the fine model in the original scene, or it can be rebuilt according to the fine model in the original scene.

[0048] S120. According to the first material parameter of the fine model in the rendering engine corresponding to the simplified model, use the pre-trained material conversion model between the rendering engine and the game engine to ...

Embodiment 2

[0068] figure 2 It is a flow chart of a scene generation method provided by Embodiment 2 of the present invention. This embodiment is an optional solution proposed on the basis of the first embodiment above. see figure 2 , the scene generation methods provided in this example include:

[0069] S210. Acquire the fine model in the original scene corresponding to the VR scene from the rendering engine; remove 80% of vertices in the fine model, and generate a simplified model whose appearance is close to the fine model.

[0070] Optionally, there are many ways to generate simple models. You can use the geometric features between the vertices of the model to obtain points with larger vertex characteristic degrees in the complex model, and then, on the basis of retaining these vertices, other points with smaller characteristic degrees Vertices and their associated edges are subjected to edge folding operations; vertex clustering algorithms can also be used to obtain simplified ...

Embodiment 3

[0087] image 3 It is a schematic structural diagram of a scene generation device provided in Embodiment 3 of the present invention. see image 3 , the scene generation device provided in this embodiment includes: an acquisition module 10 , a material parameter determination module 20 and a material setting module 30 .

[0088] Wherein, the obtaining module 10 is used to obtain a simple model for building a VR scene according to the fine model in the original scene;

[0089] The material parameter determination module 20 is used to determine the appearance of the simplified model in the game according to the first material parameter of the fine model corresponding to the simplified model in the rendering engine, using the pre-trained material conversion model between the rendering engine and the game engine. The second material parameter in the engine;

[0090] The material setting module 30 is configured to set the material of the simplified model based on the second mater...

Abstract

The embodiment of the invention discloses a scene generation method and device, belonging to the virtual reality technology field. The method comprises: according to a sizing die in an original scene, and obtaining a normal die configured to build a VR scene; according to first material parameters of the sizing die corresponding to the normal die in a render engine, employing a material transition model competed in advance between the render engine and a game engine, and determining second material parameters of the normal die in the game engine; and performing material arrangement of the normal die based on the second material parameters. According to the embodiment of the invention, the scene generation method and device realize automatic material arrangement of the built normal die and avoid a lot of duplication of labor caused by manual regulation of materials so as to improve the manufacturing efficiency of the VR scene.

Description

technical field [0001] Embodiments of the present invention relate to virtual reality technology, and in particular to a scene generation method and device. Background technique [0002] In recent years, virtual reality (Virtual Reality, VR) technology has been widely used in the field of decoration. By building VR scenes, users can experience their own design plans in person. Usually, the user drags the existing furniture model or building material model into the house model to complete the design of the scheme. After the design scheme is determined, use the rendering engine to render the design scheme, and display the rendering effect diagram. In order to provide users with realistic rendering effects, the models used in the rendering renderings are all fine models, and the fine models often have a high number of faces. [0003] Such fine models are not suitable for the real-time rendering requirements of VR scenes. Therefore, in order to make a VR scene, the existing t...
