Blur method, rendering method and computing device for visible objects

Abstract

The invention discloses a method for blurring a visible object, which is executed in a computing device. The visible object has a blurred sub-object. The method includes the steps of: obtaining pixel values ​​of the area where the visible object is located from a frame buffer, and generating the visible object. The texture map of the blurred sub-object of the visual object; the texture map is blurred to obtain the background texture map; the background texture map is written back to the corresponding area of ​​the frame buffer; the visual object is drawn to generate the foreground texture map of the visual object ; Alpha blends the background texture map with the foreground texture map to blur the rendered visual objects. The present invention also discloses a corresponding computing device.

Description

technical field [0001] The invention relates to the technical field of graphic interface display, and in particular, to a blurring method, a rendering method and a computing device of a visual object. Background technique [0002] The window manager is an application program for managing windows, for example, it can control the appearance of the window, the display position on the screen, and provide the user with a method of operating the window, and the like. The window manager can usually provide a customized title bar and border for the window visually. The title bar usually displays the window's icon, title, and buttons such as minimize, maximize, and close. In the Linux desktop environment, users can customize the title bar and borders through X11-related technologies or in a way specified by the window manager. [0003] In order to make the desktop more beautiful and easy to use, users want the background and border of the window title bar to blend with the content a...

AI Technical Summary

Problems solved by technology

[0004] At present, in the Linux desktop environment, most window managers do not support the dynamic blur effect of window title bars and borders; for a few window managers that support dynamic blur effects, their customization and aesthetics are poor, and it is difficult to meet user requirements

For example, the window manager KWin in the KDE desktop environment can only realize the motion blur of the title bars of all windows, and cannot customize the blur of one or several windows, nor does it support the motion blur of the entire window range.

In addition, KWin cannot customize the shape of the blurred area of ​​a single window, and cannot blur visual elements outside the window (such as window switching components, window preview components, etc.)
