3D character drawing method and system, readable storage medium and equipment

Abstract

The invention discloses a 3D character drawing method. The method comprises the following steps of obtaining character information and corresponding drawing attribute information; obtaining an updating flag bit of the character storage space, and judging whether the updating flag bit is set or not; if not, drawing coordinates and font sizes in the drawing attribute information are obtained, and vertex coordinates of the characters are calculated; obtaining texture information corresponding to the text information through a preset texture storage space; and sending a drawing request according to the text information, the drawing attribute information, the vertex coordinates and the texture information, and executing drawing. A character drawing process is separated into vertex calculation,character attribute management and texture management, a cache principle is fully utilized, the CPU load is reduced, the drawing efficiency is improved, communication between a CPU end and a GPU end is reduced, a GPU rendering assembly line is not interrupted, and an efficient GPU algorithm is provided. The invention further discloses a system adopting the method, a readable storage medium and equipment.

Description

technical field [0001] The present invention relates to the technical field of character display, in particular to a 3D character drawing method, system, readable storage medium and equipment. Background technique [0002] Text display is required in many graphic display-related fields, such as display control, game animation, etc. The timely display of key text is a basic requirement of a graphic display system. [0003] 2D text drawing and 3D text drawing are required in the graphic display system. Among them, the drawing of 3D text is mostly realized by the open graphics library (OpenGL), and since the OpenGL specification does not involve text drawing, there is no standard guiding OpenGL-based 3D text drawing interface, 3D text drawing Usually, 3D text drawing is implemented indirectly based on other graphics drawing interfaces provided by OpenGL. [0004] In the existing 3D text drawing methods, the text attributes are too closely related to OpenGL, and the general at...

AI Technical Summary

Problems solved by technology

[0004] In the existing 3D text drawing methods, the text attributes are too closely related to OpenGL, and the general attribute calculation and drawing attribute management of fonts are not separated from the calling process, so it is difficult to deal with complex situations, such as massive fonts Library management, dynamic changes in font size, etc., will easily lead to a huge load on the CPU during processing, resulting in low efficiency
