Abstract

The invention discloses a method and device for determining the depth of an object in a three-dimensional scene, a terminal and a storage medium. The method comprises the steps of obtaining the distance between a target object in the three-dimensional scene and a virtual camera; detecting whether the three-dimensional scene is a close-range display scene or a long-range display scene; when the three-dimensional scene is a close-range display scene, calculating a depth value of the target object by utilizing the distance and a preset first preset minimum observation distance and a preset firstpreset maximum observation distance of a virtual camera; and when the three-dimensional scene is a distant view display scene, obtaining the height from the virtual camera to the ground, determining the current minimum observation distance and the current maximum observation distance of the virtual camera based on the height, and calculating the depth value of the target object by combining the distances, the current minimum observation distance and the current maximum observation distance. By means of the mode, the precision of the depth buffer area of the overlapped image area in the three-dimensional display scene can be improved, and the problem that images flicker in the overlapped area is avoided.

Description

technical field [0001] The present application relates to the technical field of three-dimensional display, in particular to a method, device, terminal and storage medium for determining the depth of an object in a three-dimensional scene. Background technique [0002] With the development of science and technology, more and more 3D scenes are used in various industries. Usually in applications with 3D scenes, the computer needs to convert the data describing the 3D scene into 2D data for viewing on an electronic display screen. This process of converting a 3D scene into a 2D image is usually called rendering. Rendering It is generally divided into three stages: the application stage, the geometric stage and the rasterization stage. In the rasterization stage, the difference between the fixed points of the primitives obtained in the previous stage is performed to generate pixels on the screen, and the final image is rendered. [0003] The task of the rasterization stage is ...
