vtk for java 打包部署和运行

1.下载dll 和 jar 包，vs2017 安装（安装windows 必备的就可以了）

vtk.jar 下载路径

https://download.csdn.net/download/Listest/86936510

vs2017下载路径

VisualStudio2017专业版和企业版激活密钥_lovoo的博客-CSDN博客_vs2017专业版密钥

vtk.jar 下载路径：

https://mvnrepository.com/artifact/org.bioimageanalysis.icy/icy-vtk/8.0.1https://mvnrepository.com/artifact/org.bioimageanalysis.icy/icy-vtk/8.0.1dll 下载路径：https://download.csdn.net/download/Listest/86931995

2.将dll 放到jre 的bin 目录下：C:\Program Files\Java\jdk1.8.0_202\jre\bin

 3.将vtk.jar 拷贝到项目根目录下：

4.pom 文件加载本地vtk.jar 包，打包的时候要记得进行打包配置。---两个重点

 5.运行：start C:\"Program Files"\Java\jdk1.8.0_202\jre\bin\java  -Dfile.encoding=utf-8 -Dloader.path="lib/" -jar  carDataAnalyzing.jar

   6.效果如图：--目的是将点云生成obj 文件，计算点云体积。
