### 回答2：
Ubuntu 18.04是目前最受欢迎的Linux操作系统之一，它提供了许多可靠和稳定的软件包。VTK是一种流行的图形库，可用于开发2D和3D应用程序。这篇文章将会介绍如何在Ubuntu 18.04上安装VTK 7.1.1，并提供详细的步骤。

步骤一：更新系统

在安装VTK 7.1.1之前，您需要首先确保您的Ubuntu 18.04系统已经更新到最新版本。您可以使用以下命令来完成此操作：

sudo apt-get update
sudo apt-get upgrade

步骤二：安装必要的依赖项

在安装VTK 7.1.1之前，您需要安装一些必要的依赖项，以确保它能够正确地运行。您可以使用以下命令来安装这些依赖项：

sudo apt-get install libxml2-dev libjpeg-dev libtiff-dev libpng-dev zlib1g-dev libpython2.7-dev

步骤三：下载VTK的源代码

在安装VTK之前，您需要先从官方网站下载VTK的源代码。您可以使用以下命令从VTK官方网站下载最新的源代码：

wget https://www.vtk.org/files/release/7.1/VTK-7.1.1.tar.gz

步骤四：解压缩VTK的源代码

在下载完VTK的源代码之后，您需要使用以下命令解压缩它：

tar -zxvf VTK-7.1.1.tar.gz

步骤五：编译VTK的源代码

解压缩完VTK的源代码之后，您需要使用以下命令编译它：

cd VTK-7.1.1
mkdir build
cd build
cmake ..
make
sudo make install

步骤六：测试VTK的安装

完成编译和安装VTK之后，您可以使用以下命令来测试VTK的安装：

cd Examples/Gui/Qt
./CxxWidgetsConeExample

如果一切正常，您应该能够看到一个3D的圆锥体模型。

结论

在本文中，我们介绍了如何在Ubuntu 18.04上安装VTK 7.1.1。通过遵循上述步骤，您可以轻松安装和配置VTK，从而为您的2D和3D应用程序提供强大的图形库。

### 回答3：
VTK是一个开源的图形处理库，提供了许多图形处理功能，如三维可视化、数据分析、几何算法等。Ubuntu 18.04是一个流行的操作系统，下面我来介绍如何在Ubuntu 18.04上安装VTK 7.1.1。

步骤如下：

1. 准备工作：打开终端，更新软件列表，并安装一些必要的依赖库：

sudo apt-get update
sudo apt-get install build-essential cmake libgl1-mesa-dev libxt-dev libvtk7-dev

2. 下载安装VTK 7.1.1：

wget https://www.vtk.org/files/release/7.1/VTK-7.1.1.tar.gz
tar xf VTK-7.1.1.tar.gz
cd VTK-7.1.1
mkdir build
cd build

3. 配置和编译VTK：

cmake ..
make -j4

如果你拥有多个核心，可以用-j来指定使用多核心编译，这里我用了4个核心，你可以根据自己的情况适当调整。

4. 安装VTK：

sudo make install

5. 检查VTK是否成功安装：

在终端中输入vtk7，如果出现VTK的版本信息，则表示VTK已经成功安装。

至此，安装VTK 7.1.1 完成。但是，由于VTK库较大，安装时间较长，您可能需要耐心等待一段时间。

总结：在Ubuntu 18.04安装VTK 7.1.1需要先安装必要的依赖库，然后下载、配置、编译、安装VTK。安装成功后，您可以通过使用vtk7命令来测试安装是否成功。
