Image rendering method and device and electronic equipment

Abstract

The invention provides an image rendering method and device and electronic equipment. The method comprises the steps that a multi-level grid chart is acquired, wherein the multi-level grid chart comprises a plurality of hierarchical grid charts with different grid densities, each hierarchical grid chart comprises a plurality of grids, and in the multi-level grid chart, grid vertexes correspondingto the grids carry rendering control information of corresponding area positions; according to the distance between a sub-area and a virtual camera, a target hierarchical grid chart matched with the sub-area is determined from the multi-hierarchical grid chart, and a target grid is obtained from the target hierarchical grid chart; and rendering is carried out based on the rendering control information carried by the grid vertex of the target grid corresponding to the sub-area. In the mode, the grid vertex of the grid of each level corresponds to a relatively-fixed-position area, and the grid vertex carries the rendering control information of the position of the area, so that an image can be rendered more flexibly, especially for rendering of a water body, the rendering effect is more vivid, and obvious defects and flaws do not exist.

Description

technical field [0001] The present invention relates to the technical field of games, in particular to an image rendering method, device and electronic equipment. Background technique [0002] When rendering the virtual world, considering that objects that are closer to the camera occupy more screen pixels and need to have more details, they need to use more vertices, and the grid vertices are densely distributed; while objects that are farther from the camera For distant objects, since they occupy less pixels on the screen, the details cannot be seen clearly. In order to reduce the rendering overhead, a relatively small number of vertices needs to be used, and the distribution of mesh vertices is relatively sparse. In related technologies, the position of the camera is set as the center position, and a close-to-dense grid is generated according to the distance from the camera; as the camera moves continuously in the virtual world, the generated grid is also constantly movin...

Problems solved by technology

In related technologies, the position of the camera is set as the center position, and a close-to-dense grid is generated according to the distance from the camera; as the camera moves continuously in the virtual world, the generated grid is also constantly moving, based on When the moving grid renders water bodies such as rivers and lakes and rivers and lakes entering the sea, there are obvious defects, resulting in flaws in the rendering effect
