Abstract

The invention relates to a real-time adjustment method for simulating a linear light source in a 3D rendering scene. Wherein, the calculation method includes the calculation of the linear light source and the calculation of the circular arc light source, which mainly simulates the effect of the strip light in reality. This function includes: the user can adjust the rendering effect of the linear light source in the 3D scene in real time through the adjustment interface; after the adjustment is completed, the color adjustment parameters will be saved; when the scene is opened next time, the saved color adjustment parameters will be applied to the scene rendering. A main application of the present invention is to simulate the strip-shaped virtual light effect on the suspended ceiling and the background wall, and the light gradually fades from the position of the light source to the surroundings. At the same time, the user can also adjust the lighting effect according to the adjustment interface, mainly including: the color of the light source and the range of lighting. This solution improves the aesthetics and flexibility of scene rendering, and increases the user's visual experience of scene rendering.

Description

technical field

[0001] The invention relates to a computer building decoration layout, which is a real-time adjustment method for simulating a linear light source in a 3D rendering scene. It specifically involves simulating the reflection effect of linear light sources on objects in scene rendering, and the function of real-time adjustment of the effect. Background technique

[0002] In the computer architectural decoration layout, some 3D rendering engines do not have built-in linear light source objects. To render the virtual light effect produced by linear light sources on objects, a program is required to simulate the light source and perform lighting calculations. At the same time, this rendering effect is not the same for each scene or display device. If a large number of models are prepared for replacement by rendering effects of different scenes, the production cost will be greatly increased. Therefore, a function that can adjust the rendering effect in real time an...
