OpenGL-based image processor and function expansion method thereof

Abstract

The present invention discloses a function extension method of an OpenGL-based image processor, the OpenGL-based image processor, an electronic device and a computer-readable storage medium. The method comprises: adding a second renderer that implements an image processing expansion function based on an original first renderer of an OpenGL-based image processor; enabling the first renderer and thesecond renderer to share a rendering context; for one to-be-rendered specified image, inputting the specified image to the first renderer and the second renderer respectively; outputting the image rendered by the second renderer to the first renderer; and carrying out combination processing on the image rendered by the first renderer and the image rendered by the second renderer through the firstrenderer, and outputting the images. Thus, without redeveloping the image renderer, the expansion of new functions is implemented, the time and effort are saved, and the efficiency of the function expansion can be improved in a facilitated manner.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an OpenGL-based image processor function extension method, an OpenGL-based image processor, electronic equipment and a computer-readable storage medium. Background technique [0002] OpenGL (Open Graphics Library) refers to a professional graphics program interface that defines a cross-programming language and cross-platform programming interface specification. It is used for two-dimensional or three-dimensional images. It is a powerful and easy-to-call underlying graphics library. In practical applications, many image processors use OpenGL for image rendering. With the increasing demand of users for image rendering processing, the image processor with a single image rendering function can no longer meet the needs of users. Therefore, it is necessary to expand the function of the image processor. It needs to be executed independently and is relatively intrusive. For ex...

With the increasing demand of users for image rendering processing, the image processor with a single image rendering function can no longer meet the needs of users. Therefore, it is necessary to expand the function of the image processor. It needs to be executed independently and is relatively intrusive. For example, the 3D rendering function needs to redevelop the entire image processing and rendering function to realize the newly expanded functions.

That is to say, every time a new function is expanded, the image renderer needs to be redeveloped, which makes the expansion of the function of the graphics processor time-consuming and labor-intensive, and affects the efficiency of function expansion.
