Embodiment Construction

[0045] Provide the method of the present invention below, and combine Figure 1 to Figure 24 The technical details of the present invention are further given, and the advantages of the present invention are demonstrated.

[0046] One: The matrix lighting system design method of the present invention includes steps:

[0047] S1. Set up a 3D imitation skylight reflection sphere. This sphere is made of a uniform network. The present invention utilizes a grid as the spot origin position of ambient light. The grid is made up of triangular surfaces of equal size, and its number of vertices is the same as that of the light. The distribution density is correlated. When the complex value of the triangular grid of the imitation skylight reflecting sphere is set larger, the grid will be denser, and the more lights will be distributed. The grid complex value is proportional to the number of lights; the distributed lights are on the spherical surface The more common points you have, the l...

Abstract

A method for setting matrix lamp light to use 3D virtual to simulate environmental reality light includes setting up 3D reflection ball simulating sky light; connecting 3D matrix lamp light with 3D software interactively; setting matrix lamp light based on Max platform; setting virtual reality scenes and controlling lamp projection, concentration sample, projected drawing, sampling accuracy and sampling density separately in playing process of said matrix lamp light.

Description

technical field [0001] The invention relates to a setting method for quickly solving simulated ambient light irradiation, reflection and diffusion based on a three-dimensional virtual reality software (max) platform. Background technique [0002] 3DSMax rendering is a kind of linear scanning rendering widely used in 3D simulated reality animation production. In this rendering method, light is not reflected or refracted by objects, so unlike the real world, a lamp can usually illuminate a bedroom. , so we need to play dozens of lights in a scene, and the number of lights will be more when making animations. The process of making with 3DSMax tools is a process of observation and analysis. Regardless of whether the scene to be created is a real thing or an idea in the author's mind, it must be carefully observed, because the premise of using 3DSMax light is to understand the properties of light in the real environment, and then follow the generation, transmission, distribution...
