Abstract

The latest generation of graphics hardware provides direct access to multisample anti-aliasing (MSAA) rendering data. By taking advantage of these existing pixel subsample values, an intelligent reconstruction filter can be computed using programmable GPU shader units. This paper describes an adaptive anti-aliasing (AA) filter for real-time rendering on the GPU. Improved quality is achieved by using information from neighboring pixel samples to compute both an approximation of the gradient of primitive edges and the final pixel color.
一种方向自适应边缘抗混叠滤波器
最新一代的图形硬件提供了对多样本抗混叠(MSAA)渲染数据的直接访问。通过利用这些现有的像素子样本值,可以使用可编程GPU着色器单元计算智能重建滤波器。本文介绍了一种用于GPU实时渲染的自适应抗混叠(AA)滤波器。通过使用来自相邻像素样本的信息来计算原始边缘梯度的近似值和最终像素颜色来提高质量。
