问题 I've been doing a lot of voxel terrain generation with JavaFX 3D. For some reason, whenever I generate a landscape, the right side of the landscape will always have these weird black lines. I've tried changing the PerspectiveCamera 's near and far clip values, but they seem to have no effect. In case you need it, my near clip value is set to 0.1 and my far clip value is set to 100000.0 . Here is a picture of my program, as you can see, there are clear visual glitches present mainly on the

Chaos Mesh —— 让应用跟混沌在 Kubernetes 上共舞

阅读更多关于 Chaos Mesh —— 让应用跟混沌在 Kubernetes 上共舞

作者：殷成文 2019 年 12 月 31 日，我们在 GitHub 上正式开源了 Chaos Mesh。作为一个云原生的混沌测试平台，Chaos Mesh 提供在 Kubernetes 平台上进行混沌测试的能力。本篇文章将围绕 Chaos Mesh 起源及原理等方面进行介绍，并结合具体案例带领大家一起探索混沌测试的世界。现实世界中，各类故障可能会随时随地的发生，其中有很多故障我们无法避免，例如磁盘突然写坏，或者机房突然断网断电等等。这些故障可能会给公司造成巨大损失，因此提升系统对于故障的容忍度成为很多工程师努力的目标。为了更方便地验证系统对于各种故障的容忍能力，Netflix 创造了一只名为 Chaos 的猴子，并且将它放到 AWS 云上，用于向基础设施以及业务系统中注入各类故障类型。这只 “猴子” 就是混沌工程起源。在 PingCAP 我们也面临同样的问题，所以在很早的时候就开始探索混沌工程，并逐渐在公司内部实践落地。在最初的实践中我们为 TiDB 定制了一套自动化测试平台，在平台中我们可以自己定义测试场景，并支持模拟各类错误情况。但是由于 TiDB 生态的不断成熟，各类周边工具 TiDB Binlog 、 TiDB Data Migration 、 TiDB Lightning 等的出现，测试需求也越来越多，逐渐出现了各个组件的的测试框架。但是混沌实验的需求是共有的

下层传输层主要负责数据的分段与重组。下层传输层接收上层传输层的Access消息和Control消息。 1. 分段消息（Segmented Msg） 1.1. 分段接入层消息（Segmented Access Message）分段接入层消息（ 5-16字节）的每个分段的结构如下： Field Size(bits) Notes SEG 1 SEG=1，表示当前消息是分段消息 AKF 1 AKF=1，表示使用Appkey加密；AKF=0，表示使用DevKey加密，AID=0b000000 AID 6 AppKey ID，当AKF= 1时有效 SZMIC 1 TtansMIC的大小。SZMIC=0，表示TransMIC为4字节；SZMIC=1，表示TransMIC为8字节 SeqZero 13 SeqAuth 的最低13位有效位 SegO 5 表示当前分段位第几个分段 SegN 5 表示此条消息总共有多少分段 Segment m 8-96 此分段的消息内容，只有最后一个分段的size才小于96 SeqN为5bit，说明最大支持32个分段，每个分段满载的payload为12字节，所以Upper Transport Layer下发的消息包括TransMIC最大为32*12=384字节。对于同一条消息的不同分段，只有SegN和Segment m不同。 SeqAuth是第一个分段的IV

Selection of Face of a STL by Face Normal value Threshold

阅读更多关于 Selection of Face of a STL by Face Normal value Threshold

问题 I want to write a script in Python which can generate facegroups in a STL as per the Face Normal value condition. For example, Provided is the snap of Stl, Different colour signifies the face group containing the triangular faces satisfying my given face normal threshold. Is there any simple way to do this in python? Face Group STL 回答1: I'm sure there's a python library to load stl files, but I've always just written my own, since the file format is pretty simple (see the Wikipedia article

SceneKit: advice on reproducing glowing light trail like with Tron light cycles

阅读更多关于 SceneKit: advice on reproducing glowing light trail like with Tron light cycles

问题 The goal is to reproduce a light trail similar to the image below in SceneKit. The trail doesn't need to be as detailed, but the idea is to achieve a similar visual effect. We tried using thin cubes with opacity around 0.5. We strung about 200 together and attached them to a node to act as a light trail. That was not performant at all. This other post suggests using particle emitters, but we also need to detect collisions when another object hits the trail. Class documentation says collision
