2016-03-07 Categorized in GC Algoritm. 深度缓冲的分辨率对于场景质量有很大的影响 当两个物体非常接近的时候，16位的深度缓冲区可能会导致 z缓冲区fighting 的人为噪声 使用24位或者32位的深度缓冲区就会表现得较好 由于精度太低，所以很少使用8位的深度缓冲区。 结果z'是在 -1到1之间归一化之后的值，其中近距near 平面位于 -1处，远距far平面位于1处。 F=far, N=near, Z=final return. Z=( f n)/(f-n) ( 1.

Buffered I/O Methods for Text Files. The java.nio.file package supports channel I/O, which moves data in buffers, bypassing some of the layers that can bottleneck stream I/O. Reading a File by Using Buffered Stream I/O. The newBufferedReader(Path, Charset) method opens a file for reading, returning a BufferedReader that can be used to read text from a file in an efficient manner. Charset charset = Charset.forName( "US-ASCII". Reader = Files.newBufferedReader(file, charset) {. System.out. println.

Viewport是网页默认的宽度和高度，上面这行代码的意思是，网页宽度默认等于屏幕宽度 width=device-width ，原始缩放比例 initial-scale=1 为1.0，即网页初始大小占屏幕面积的100%。 对于那些老式浏览器 主要是IE6、7、8 ，需要使用css3-mediaqueries.js。 If lt IE 9]. 字体也不能使用绝对大小 px ，而只能使用相对大小 em。 Helvetica, Arial, sans-serif.

2016-02-22 Categorized in Android. 在 /application 标签和 /manifest 标签之间添加上面那段代码。 Android 应用程序自适应屏幕大小和layout 的布局 一 不同的layout. Android手机屏幕大小不一，有480x320, 640x360, 800x480.怎样才能让App自动适应不同的屏幕呢 其实很简单，只需要在res目录下创建不同的layout文件夹，比如layout-640x360,layout-800x480,所有的layout文件在编译之. 1)drawable-hdpi里面存放高分辨率的图片,如WVGA (480x800),FWVGA (480x854). 还要说明一点 每个activity都有这个属性screenOrientation，每个activity都需要设置，可以设置为竖屏 portrait ，也可以.
