Rendering method and device

Abstract

The embodiment of the present invention discloses a rendering method and device; the embodiment of the present invention can determine the target pixel in the virtual scene and obtain the number of iterations at the current moment; perform path tracking on the target pixel based on the number of iterations at the current moment to obtain the target The ray path of the pixel at the current moment; determine the iteration state of the ray path at the current moment; when the iteration state is the stop iteration state, render the target pixel based on the ray path at the current moment. The embodiment of the present invention can automatically determine whether to continue to iterate to accurately render the target pixel. Therefore, this solution can improve the efficiency of pixel rendering.

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.
