Entity material quality replacement method based on three-dimensional virtual platform

Abstract

The invention discloses an entity material quality replacement method based on a three-dimensional virtual platform. The entity material quality replacement method based on the three-dimensional virtual platform comprises the following steps that a three-dimensional render engine is initialized, an initial position of a virtual camera in a scene is set, the size of a viewport is set, after a user selects the scene, scene data is read from scene organization files, entity data is read from material files, an illumination effect of the scene is loaded, a software interface is initialized, a texture mapping menu which comprises a plurality of various thumbnails of texture mappings is displayed, wherein the thumbnails can be dragged, a user selects a texture mapping from the texture mapping menu, and drags the texture mapping to the scene, software confirms a three-dimensional coordinate of the scene of a needed position through drag operation of the user, material quality need replacing is confirmed through the three-dimensional coordinate, when the material quality is confirmed, the texture mapping in the entity texture mapping is carried out with appropriate scaling by the selected texture mapping in the texture mapping menu and is replaced by the selected texture mapping in the texture mapping menu, and the scene is saved. The entity material quality replacement method based on the three-dimensional virtual platform achieves immediate render.

Description

technical field [0001] The invention belongs to the technical field of computer virtual reality, and in particular relates to a method for replacing solid materials based on a three-dimensional virtual platform. Background technique [0002] 1. Virtual reality is to use computer simulation to generate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, and can observe things in three-dimensional space in a timely and unlimited manner. However, the operating system and application software usually cannot directly use the graphics card and the 3D acceleration function in it, and must pass OpenGL (OpenGL is a professional graphics program interface, a powerful, easy-to-call underlying graphics library) and Direct3D (Direct3D is a Microsoft Corporation An interface of a set of 3D drawing programming interfaces developed on the Microsoft Windows operating system) to call. [0003] 2. The entities in the virtual world sc...

However, in the real-time experience of the scene, when the customer replaces the appearance pattern of an entity, that is to say, when the system replaces the material of an entity, it needs to process a large number of lighting parameters, which will take a long time for rendering and cannot reach purpose of instant rendering
