Method and device for selecting materials for objects in 3D scene

Abstract

The invention provides a method and device for selecting materials for objects in a 3D scene. The method comprises that a material database is inquired to obtain information of candidate materials corresponding to the objects and probabilistic relations between the objects and the corresponding candidate materials; according to the information of the candidate materials corresponding to the objects, different material combination manners of the objects are determined; according to the probabilistic relations, the material combination probability of each of the multiple material combination manner is determined; each material combination manner is compared with a preset reference template, and the preferable degree of each material combination manner is determined; according to the material combination probabilities and the preferable degrees, a target material combination manner is selected form the material combination manners; and the objects are rendered according to a target material. Thus, the target material of a better matching effect can be selected for the objects.

Description

technical field [0001] Embodiments of the present invention relate to the field of three-dimensional scenes, and more specifically, relate to a method and device for selecting materials for objects in three-dimensional scenes. Background technique [0002] In the texture mapping and rendering of 3D scenes, selecting materials for objects is a very important process. For the same scene, choosing different material combinations may present completely different visual effects. In order to be able to select a material combination scheme for objects in a 3D scene more conveniently, in the prior art, a material combination scheme is selected for an object in a 3D scene according to the corresponding relationship between object materials and geometric shapes extracted from a small number of high-quality 3D scene model libraries. . The existing technology mainly has the following problems in the process of selecting material combination schemes: firstly, the number of free high-qua...

Problems solved by technology

The existing technology mainly has the following problems in the process of selecting material combination schemes: firstly, the number of free high-quality 3D scene models is very small, so it is difficult to obtain a more accurate correspondence between object materials and geometric shapes; in addition, the The method only considers the corresponding relationship between the geometric shape and the material of th...
