Abstract

The invention relates to a method and system for rendering optimization of a glow effect. The method comprises the steps: rendering a scene through a floating point type rendering target, and writinga Bloom intensity coefficient into an alpha channel of the rendering target; carrying out fuzzy sampling, and reducing the resolution to a first resolution; according to the Bloom brightness minimum threshold, carrying out color extraction on the rendering target Bloom with the first resolution, and carrying out fuzzy processing; presetting down-sampling times to carry out down-sampling to obtainrendering targets with different resolution textures, and respectively carrying out fuzzy processing; combining the different rendering targets subjected to fuzzy color extraction and then combining the different rendering targets into a main rendering target; and finally converting into a common rendering target through a tone mapping formula, superposing brightness, adjusting saturation, and finishing color output. According to the invention, the problems of hardware resource overload, weak Bloom detail control force and insufficient glow effect are solved, bandwidth and video memory are saved, and excellent glow effect is simultaneously considered.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method and system for rendering optimization of glow effects. Background technique [0002] With the rapid development of information technology, online games on various mobile platforms are also developing more and more rapidly. Among them, Bloom is a computer graphics effect used for video games, presentations and high dynamic range rendering. Bloom effect is also used in games. A common screen special effect, combined with high-dynamic range technology (High-Dynamic Range, referred to as HDR) in mobile phones, can burst out a large halo effect, and can achieve high-frequency glow effects on mobile platforms. The effect produces streaks that extend from the edges of bright areas into the image, creating an illusion of intense light that prevents the camera or eye from capturing the scene. [0003] In related technologies, the Bloom effect has poor performance on mobile pho...
