Anti-aliasing is a technique used in computer graphics to smooth out jagged edges in digital images, particularly in games and other 3D rendered environments. These jagged edges, often called “jaggies” or “the staircase effect,” occur when diagonal or curved lines are displayed on a pixel-...
Basically, the sawtooth problem in the game greatly affects the game's senses. But in terms of the current anti-aliasing technology, there are some problems, such as the blurring of TAA, FXAA. the SSAA , MSAA anti-aliasing quality is very good, but it consumes too much performance. Let'...
使用相同的采样频率,f大的函数很难被充分采样。 高频信号未被充分采样,采样后得到的是一个低频信号。 在给定的采样频率中得到的两个频率函数无法区分,则被称为走样。 滤波:去除特定的频率内容 Filtering = Convolution = Average 卷积: 卷积定律: 空间域两个信号的卷积对应频域两个信号的乘积 方法1 空间域 卷积滤...
What Is Aliasing and Anti-Aliasing? Aliasing in images and PC games occurs when the edges of the pixels appear jagged like a staircase. Anti-aliasing methods usually involve softening the jagged appearance of lines through the addition of shaded pixels or blurring the edges of an image. What I...
It’s very fast and can be applied to any image, making it popular in games that need to maintain high frame rates. 4. Temporal Anti-Aliasing (TAA): This method uses information from previous frames to smooth out edges, providing good results with relatively low performance impact. TAA can...
You can still find the olderDLSS 1.0version in some games and while it can sometimes improve performance, the impact on the image quality is usually not worth it. Just like DLSS 2,DLAA(Deep Learning Anti-Aliasing) uses machine learning to improve image quality but doesn’t use upscaling. So...
本文由Playdead Games的高级程序员Lasse介绍,主要讨论了在即将发布的游戏INSIDE中应用的时间重投影抗锯齿技术。INSIDE是一款结合解谜、平台跳跃和探索的横版游戏,游戏内包含大量几何细节和透明层。为了获得干净稳定的图像,团队从2014年开始研究时间抗锯齿技术,并迅速将其作为主要解决方案。时间抗锯齿是一种利用多帧之间片段...
