Abstract

The present invention provides a three-dimensional graph rendering method, apparatus and equipment and storage medium. The method comprises a step of obtaining first point coordinates, second point coordinates and third point coordinates, a step of taking the first point coordinates and the second point coordinates as center point coordinates and contour point coordinates of a bottom surface contour in a three-dimensional graph to be rendered, and combined with the relation between each specified contour point and a center point on the bottom surface contour of a preset standard three-dimensional graph, determining a first zoom ratio of the bottom surface contour of the three-dimensional graph to be rendered to the bottom surface contour of the standard three-dimensional graph, a step of drawing the bottom surface contour of the three-dimensional graph to be rendered based on the first zoom ratio, and a step of drawing the contours of other surfaces in the three-dimensional graph to be rendered according to the distances of the second point coordinates and the third point coordinates and the extension direction of the side surface contour in the standard three-dimensional graph. According to the three-dimensional graph rendering method, apparatus and equipment and the storage medium, a three-dimensional graph expected by a user can be drawn, and thus the accuracy of drawing three-dimensional graph is improved.

Description

technical field [0001] The invention relates to the technical field of drawing, in particular to a three-dimensional figure drawing method, device, equipment and storage medium. Background technique [0002] At present, in scenes such as teaching and drawing, drawing of three-dimensional graphics is often involved. Stereoscopic graphics can be understood as graphics formed by projecting a three-dimensional body onto a two-dimensional plane according to specified projection conditions, or as graphics drawn to display a three-dimensional body with a specific viewing angle on a two-dimensional plane. Wherein, the three-dimensional body may be a cylinder, a cone, a column whose two bases are regular polygons and whose bases are parallel, and the like. [0003] In the related art, the three-dimensional graphics samples can be pre-stored in the drawing software, and the three-dimensional graphics samples can be dragged out from the tool bar of the drawing software according to us...
