翻译自https://unity3d.com/cn/learn/tutorials/topics/best-practices/fill-rate-canvases-and-input?playlist=30089#anchor-fn-2 这一章讨论一下在构建Unity UI时容易碰到的问题. 解决填充率问题 有两种方法可以减轻GPU片段管线的压力: * 减少片段shader的复杂度 - 更多详细信息,请看"UI Shader和低端设备"部分. * 减少必须被采样的像素点的数量. 由于…

CPU bound:CPU性能边界,是指CPU计算时一直处于占用率很高的情况. GPU bound:GPU性能边界,同样的是指GPU计算时一直处于占用率很高的情况. 原文:https://unity3d.com/cn/learn/tutorials/temas/performance-optimization/optimizing-graphics-rendering-unity-games?playlist=44069   简介 在这篇文章中,我们将学习Unity渲染一帧时在幕后会发生什么,渲…

本文目标:如何创建一个高质量的H.264视频 x264 是一个 H.264 编码器. 通常有2种码率控制(rate control)模式:Constant Rate Factor (CRF) or Two-Pass ABR 码率控制是一种决定为每一帧分配多少比特数bits的方法,它将决定文件的大小和质量的分配how quality is distributed. CRF恒定比率因子 目的是为了使整个文件达到特定的输出质量,而不关心文件大小:此方法在1pass时就可以提供最大的压缩效率.每一帧都得…

像rate评分组件一般都用javascript写,所以这次将是一个全新的尝试,用css实现一个rate评分 ❗ 核心代码也就三行? 01 效果图 02 原理 主要是借助radio单选框,梳理如下: 去找个好看的iconfont: 借用5个radio单选框,把默认样式都去掉,显示默认的星星: 用checked伪类监听用户选中✅,由默认的星星变成高亮的星星: 然后配合~兄弟操作符把当前选中的所有兄弟元素都一起高亮?: 把5个radio单选框反向排列❗: 03 代码 这是我事先生成好的iconfont…

SparkStreaming 分析 (基于1.5版本源码) SparkStreaming 介绍 SparkStreaming是一个流式批处理框架,它的核心执行引擎是Spark,适合处理实时数据与历史数据混合处理的场景.其处理流程如下: 1.    接收实时流数据并持久化 2.    将实时流以时间片切分成多个批次 3.    将每块(一个批次)的数据做为RDD,并用RDD操作处理数据 4.    每块数据生成一个SparkJob,提交Spark进行处理,并返回结果 Dstream 介绍 Spar…
