Abstract

The invention discloses a large-scale three-dimensional group performance animation parallel rendering method based on PBRT, including a preprocessing stage: combining 3ds Max software and a PBRT rendering plug-in, exporting relevant rendering data suitable for a PBRT rendering program, and then generating actions and Write the location data into the rendering script file corresponding to PBRT, and generate PBRT main rendering files in batches; parallel computing resource configuration stage: according to the currently available computing resources, assign the PBRT main rendering files corresponding to the entire animation to be rendered to different computing resources On different processors of the node, and then call the PBRT rendering program in parallel to render, and get the numbered picture sequence; post-processing stage: synthesize the rendered numbered picture sequence into an animation video, and finally get a high-fidelity Sense of three-dimensional group performance animation.

Description

technical field [0001] The invention belongs to the field of three-dimensional animation synthesis, in particular to a PBRT-based large-scale three-dimensional group performance animation parallel rendering method. Background technique [0002] 3D animation rendering technology can be roughly divided into two categories, one is real-time rendering (Real-time Rendering), which is often used in 3D games, and the other is Offline Rendering (Offline Rendering), which is widely used in animation and film production. . The former has to compromise on image quality because of the need to ensure the rendering speed, while the latter can pursue the realism of the picture regardless of the cost. [0003] There are two main goals of 3D animation rendering. One is to require the animation effect to have a very strong sense of reality, and the other is to provide good interactivity during the rendering process, so as to achieve real-time purposes. Although current PCs have abundant sto...
