Problems solved by technology

Among them, the graphics that can be drawn by the DOM rendering method are limited by the HTML tag type and the operating range of DOM nodes. It can only draw simple 2D graphics such as rectangles and circles, and it is difficult to draw complex 2D graphics such as polygons and irregular curves.
Although the Canvas API-based method can draw complex 2D graphics, it only supports drawing basic 3D graphics, and when drawing basic 3D graphics or drawing multiple images at the same time, it is easy to cause the Canvas API to freeze.

Abstract

The invention discloses a graph drawing method and device, terminal equipment and a storage medium. The method comprises the following steps: constructing an HTML5 (Hypertext Markup Language) canvas label, and acquiring a WebGL context object according to the HTML5 canvas label; and verifying the WebGL context object, and calling a WebGL API to draw a graph of a target image when the verificationsucceeds. According to the method, the WebGL API can be called to realize graph drawing, so that the graph display effect and drawing efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of computer graphic drawing, in particular to a graphic drawing method, device terminal equipment and storage medium. Background technique [0002] As an important task of computer vision, image annotation mainly adopts the method based on DOM rendering and the method based on Canvas API to realize graphical annotation. Among them, the graphics that can be drawn by the method based on DOM rendering are limited by the type of HTML tags and the operating range of DOM nodes. It can only draw simple 2D graphics such as rectangles and circles, and it is difficult to draw complex 2D graphics such as polygons and irregular curves. Although the Canvas API-based method can draw complex 2D graphics, it only supports drawing basic 3D graphics, and when drawing basic 3D graphics or drawing multiple images at the same time, it is easy to cause the Canvas API to freeze. . Contents of the invention [0003] The inventi...
