Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a light display method and device. Background technique [0002] Ray tracing is a method of rendering three-dimensional images on a two-dimensional screen and is widely used in computer games and animation, television and DVD production, and film productions. In ray tracing techniques, the path of each ray consists of multiple straight lines, almost always involving reflection, refraction and shadowing effects from the origin to the scene. In animation, the position and direction of the straight portion of each ray is always changing, so each ray is represented by a mathematical equation that defines the ray's spatial path as a function of time. Each ray is assigned a color based on the pigment, or color, of objects in the scene it passes through before reaching the screen. Every pixel on the screen corresponds to every ray of light that can be traced back to the sour...

Problems solved by technology

[0004] In the existing methods involving ray tracing technology, since the final construction is a three-dimensional image, the light rays in the process of constructing the three-dimensional image are invisible, and the construction process of each pixel in the three-dimensional image cannot be observed intuitively, and The ray tracing algorithm cannot be debugged before the 3D image construction is completed, which makes the debugging of the ray tracing algorithm difficult and expensive
