摘　　要：传统像素化的非真实感渲染方法,大多存在操作复杂,需要手动调节众多参数,时间复杂度极高等相关问题。针对以上问题,本文提出了一种高性能实时像素化非真实感渲染方法,该方法首先设计光照模型,随后通过边缘检测提取出目标对象的边缘,进行插值计算对图像做像素化处理,最后将光照模型效果与抖动效果处理相结合,进行抖动风格化效果实时渲染,实验表明本文提出的高性能实时像素化非真实感渲染方法与传统的像素化方法相比,降低了计算的时间复杂度,简化了调节步骤,提升了渲染效果。Traditional pixelated non-photorealistic rendering methods often suffer from problems such as complicated operations, manual adjustment of numerous parameters, and extremely high time complexity. To address these issues, this paper proposes a high-performance real-time pixelated non-photorealistic rendering method. Firstly, a lighting model is designed, followed by edge detection to extract the edges of the target object. Interpolation is then applied to pixelate the image, with the lighting model effect combined with dither effect processing for real-time rendering of dither stylization effects. The experimental results show that the proposed high-performance real-time pixelated non-photorealistic rendering method reduces the time complexity and simplifies the adjustment steps compared with traditional pixelation methods, while improving the rendering effect.
