引言

本文记录使用vtk创建一个圆柱体。

开发环境

使用QtCreator4.11.2创建一个空项目，使用的vtk9.2的库和头文件，基于Qt5.14.2。

示例

这里提供pro文件中的内容和main.cpp中的内容。内容如下：
.pro

QT       += core#greaterThan(QT_MAJOR_VERSION, 4): QT += widgetsCONFIG += c++11 vtk9.2# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0SOURCES += \main.cppSOUPDIR = $$PWD/../../SOUPdependency

}# Default rules for deployment.
