Real-time rendering method and mobile terminal

Abstract

The invention provides a real-time rendering method and device. The method includes the steps that a three-dimensional house type space to be rendered is partitioned, and multiple subspaces corresponding to single rooms are generated; a preset number of light sources are arranged for each subspace, and the coverage range of the light sources is adjusted based on the size of the subspaces; the subspaces are rendered in real time based on the adjusted light sources. The subspaces based on space partitioning are rendered respectively, so that the complexity of illumination calculation in rendering is lowered, the rendering efficiency is improved, the rendering fidelity is improved, and objects in rooms have the diffuse reflection and highlight effects.

Description

technical field [0001] The invention relates to the field of computers, in particular to a real-time rendering method and a mobile terminal. Background technique [0002] The existing home design software is mainly divided into two categories: [0003] The first type is professional 3D modeling software. The working process of this type of model is: firstly, through the construction of the 3D model, and then through offline rendering, render a high-definition rendering to check the effect of the room. The advantage is that the rendering can reach the effect of a photo. Level, however, its working process is based on the existing house type. In order to show the real natural lighting, it uses the global illumination model for baking and rendering. Since the lighting information of the global lighting is baked into the light map, so every Each apartment type corresponds to a piece of lightmap data, so once the apartment type changes, the baked lighting information must be rec...

AI Technical Summary

Problems solved by technology

It is precisely because of this complex algorithm that it takes up a lot of memory and takes a long time to render, so this kind of method is not suitable for home design software that can be edited on the mobile side

In addition, it cannot edit the model in real time after dyeing

[0004] The second category is mobile-end home design software. This type of software does not use the calculation method of global illumination, but uses color maps to maintain the brightness of the entire scene without calculating the illumination. This method has no excessive layer effects

Some methods combine the way of parallel light to illuminate the scene, but because there is no calculation of reflected light source, only the surface of the object within the projection direction has the influence of light source. Since the space of the room is a closed space, parallel light can only shine into the room from the window , therefore, parallel light has no effect on the walls and objects in the room except for the shadow effect of simulating the light entering the window

With this kind of software, you can directly view the 3D effect of the house type after building the house type, but it has almost no lighting calculation effect, and cannot reflect the light receiving effect of the room and the objects in the room

[0005] It can be seen that in the home design software in the prior art, for the editable three-dimensional apartment space on the mobile terminal, parallel light entering the space from the window cannot simulate the transition effect of space light, and there is still a problem of low efficiency, and real-time rendering When , the wall has no diffuse reflection, the object has no diffuse reflection, and there is no defect of highlight effect
