【GAMES101-现代计算机图形学课程笔记】Lecture 05 Rasterization 2 (Antialiasing and Z-Buffering)
1.2 本节内容概要： Antialiasing Sampling theory Antialiasing in practice Visibility / occlusion Z-buffering 一种反走样（Antialiasing）的方法是对原图先做模糊处理（滤波），然后再采样。 image.png （注意：上图表示的是频域上的信号表示，横轴表示频率，纵轴表示幅度，即信号强度） 3.6 反走样(Antialiasing) 上面介绍了走样发生的原因，那么如何反走样呢？ Antialiasing By Supersampling (MSAA) 上面对每个像素内部做平均计算不太好计算，所以一种改进的算法MSAA诞生了。

Qt抗锯齿操作
❞ 使用QPainter抗锯齿 QPainter painter(this); /* 尽可能消除锯齿边缘 */ painter.setRenderHint(QPainter::Antialiasing) TextAntialiasing); /* 启用线性插值算法以此来平滑图片 */ painter.setRenderHint(QPainter::SmoothPixmapTransform); 启用antialiasing 属性 QML中所有继承于Item的元素都具备antialiasing属性(默认不启用)。 如： Rectangle { antialiasing: true } 所有继承于QQuickItem类都具备设置抗锯齿属性(默认不启用)。
