前言

测试代码，最简化输出点云图像

一、界面

添加OpenGL Widget，并提升为QVTKOpenGLNativeWidget

二、代码

1、pro文件

 新建工程文件后，在pro文件最后添加

ENV = F:/Environment
#-----------PCL配置-----------
include($$ENV/Qt_PCL-1.14.1.pri)

 先用上面的配置，有问题再从下面寻找添加合适的代码

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++11

# 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 6.0.0
