回顾和本节摘要 1.1 上一节内容回顾 Viewing View + Projection + Viewport(将cuboid变换到屏幕空间) Rasterizing triangles Point-in-triangle
合成 绘图的步骤称为 rasterizing(光栅化)。在 Chrome 最早发布时,采用了一种较为简单的光栅化方案,即仅渲染可是区域内的像素点,当滚动后,再补充渲染当前滚动位置的像素点。
光栅化 转换几何形状数据为帧缓存中的颜色像素,叫做点阵化(rasterizing),也叫光栅化。 每个颜色像素叫做片元(fragment)。 纹理坐标系 ?
SHM upload: instead of rasterizing into a void* from the renderer heap, we allocate a shared memory buffer
Text pre-caching, asynchronous and partial texture updates are all important optimizations but rasterizing
将此信息转换为屏幕上的像素称为光栅化(rasterizing)。 光栅化是将几何数据经过一系列变换后最终转换为像素,从而呈现在显示设备上的过程。
将以上这些信息转化为显示器的像素的过程叫做光栅化(rasterizing)。 可能一个最简单的做法就是只光栅化视口内(viewport)的网页内容。
转换几何形状数据为帧缓存中的颜色像素,叫做点阵化(rasterizing),也叫光栅化。其实就是根据顶点的数据,检测像素中心是否在三角形内,确定具体哪些像素需要渲染。
将以上这些信息转化为显示器的像素的过程叫做光栅化(rasterizing)。 可能一个最简单的做法就是只光栅化视口内(viewport)的网页内容。
Suppose you want a shortcut for rasterizing a PostScript file at 150 dpi, using the standard output stream
