Embodiment Construction

[0094]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0095] see figure 1 , is a schematic flow chart of lens flare drawing provided in Embodiment 1 of the present invention. Such as figure 1 The lens flare drawing method shown includes steps:

[0096] S1. Receive input parameters of several lens flares, and pass them into the shader in turn;

[0097] Wherein, the parameters of the lens flare can be set and input by the user, including one or more of texture index, color, size, offset, yes / no rotation, brightness, t...

Abstract

The invention discloses a lens flare drawing method and device. Texture mappings required by a plurality of lens flares are combined into a big texture mapping, and the big texture mapping is submitted to the cache of a graphics processing unit; then, in a three-dimensional scene, a flare model is established; according to the input parameters of a plurality of lens flares and a current scene, the attribute of each lens flare is regulated in real time; according to the attribute of each lens flare, a quadrangular surface patch is called to read a big texture mapping cache; and each lens flare is drawn through a shader. By use of the scheme, a picture mapping way is used for drawing the lens flare, and a plurality of lens flares can be drawn in one batch through the quadrangular surface patch and the big texture mapping to save drawing expenditures. In addition, the parameters of the lens flares can be set and input by design personnel, so that the parameters have diversified styles and are flexible in configuration, and the problems that existing lens flare drawing is high in expenditure and can not be configured are solved.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a lens flare drawing method and device. Background technique [0002] With the popularization of smartphones and tablet computers, games on mobile terminals have also developed. With the development of the mobile game industry, more and more advanced rendering effects have begun to appear on users of mobile phones and tablet computers. In particular, the lens flare effect that can show the level of image quality, that is, the lens flare effect, is gradually used in mobile games. Lens flare is an optical phenomenon such as reflection, refraction, and diffraction of light inside the lens, which forms a glare effect in the photos and videos taken. [0003] There are physically based, photorealistic, lens flare rendering techniques, but they are computationally expensive and require complex preprocessing. Moreover, mature mobile game engines, such as unity, have simple lens flare f...
