Embodiment Construction

[0016] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The so-called radiosity parallelism is a method of multi-machine parallel computing, which is used to improve the overall efficiency of the radiosity rendering algorithm and solve the problem that the speed of the single-machine algorithm is too slow. For the description of the radiosity algorithm, please refer to http: / / dev. gameres.com / Program / Visual / 3D / Radiosity_Translation.htm. The principle of the radiosity algorithm is to simulate the lighting principle in the real world, collect all the color information that can be seen at each position in the scene, and then summarize the color information as the final color of the position and Colorize the current position. In the real world, this position represents an infinite ...

Abstract

The invention relates to a system for radiation intensity parallel rendering for an indoor scene. The system is characterized by comprising the following modules: a master node (1), rendering task child nodes (2), a task manager (3) and a file server (4), wherein the master node (1) is used for responding interaction control of a user, communicating with the task manager (3) and all rendering task child nodes (2) and displaying rendering results and relevant statistical data in real time; the rendering task child nodes (2) are used for carrying out rendering tasks and completing global illumination rendering tasks through central processing unit (CPU) or graphics processing unit (GPU) hardware acceleration; the task manager (3) is used for dynamic allocation of rendering tasks according to the node number, the node hardware information and the network state of the rendering task child nodes (2); the file server (4) is used for temporary storage of all files which are generated in the process of rendering, wherein the files includes intermediate result files, configuration files, final result files and house type data files.

Description

technical field [0001] The invention belongs to the technical field of computer-aided design, and in particular relates to a system and method for radiance parallel rendering of indoor scenes, which are used for indoor scenes in virtual reality. Background technique [0002] In the field of virtual reality, interior design realistic rendering has a wide range of applications as an important specific field, such as game scenes, real estate display, safety preview, architectural design evaluation and other fields, all of which have urgent requirements for realistic rendering effects. Faced with this demand, the commonly used solution nowadays is to manually model by artists. Through some advanced rendering tools, after a long period of parameter setting and rendering, a frame of pictures can be generated, and once the rendering is completed, it is impossible to enter Walk through the rendered photorealistic scene. This method not only consumes a lot of human and financial res...
