Rendering method and device

Abstract

The embodiment of the invention discloses a rendering method and device. According to the embodiment of the invention, determining the target pixel point in the virtual scene, and obtaining the iteration frequency at the current moment; performing path tracking on the target pixel point based on the number of iterations at the current moment to obtain a light path of the target pixel point at thecurrent moment; determining an iterative state of the light path at the current moment; and when the iteration state is an iteration stopping state, rendering the target pixel point based on the lightpath at the current moment. According to the embodiment of the invention, whether iteration needs to be continued to render the target pixel accurately or not can be automatically judged. Therefore,the scheme can improve the pixel rendering efficiency.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a rendering method and device. Background technique [0002] Ray tracing (Ray Tracing) is a method for presenting a three-dimensional image on a two-dimensional screen. Currently, ray tracing is widely used in fields such as computer games, animation, and multimedia production. In the process of ray tracing, the path of each ray means that the ray is emitted from the origin and undergoes a series of diffuse reflection, refraction and shadow effects after encountering a virtual object in the virtual scene. The path of each ray reaches the screen Multiple virtual objects previously encountered can give the light's path different color contributions during the process of diffuse reflection, refraction and shadow effects. [0003] The more the number of diffuse reflection, refraction and shadow effects, the more realistic the image rendering, however, in the process of multiple diffu...

Problems solved by technology

[0003] The more the number of diffuse reflection, refraction and shadow effects, the more realistic the image rendering, however, in the process of multiple diffuse reflection, refraction and shadow effects, the color contribution of the virtual object to the path of the light is less and less, but However, it consumes a lot of computing resources. Therefore, the current method of pixel rendering using ray tracing consumes a lot of computing resources, so the current rendering method is inefficient.
