在QT中使用Q3Dsurface绘制三维图。项目需要，而大部分教程都是比较简单的绘制，不能满足需求，本教程将三维数组数据绘制成三维曲面，在绘制三维曲面时，我原本以为是给入数据，然后由框架拟合出曲面，其实不是，本质上是一个一个点连接的，需要按顺序连接好节点，即一行一列连接，否则曲面就会看不出形状。
QT编译器采用的是MSVC2017 64bit

Q3Dsurface属于datavisualizationd组件，需要添加相应配置
// pro文件添加
QT += datavisualization
// 头文件添加
#include <QtDataVisualization>
#include <QSurface>
// 更新一下，还得加两个东西
// 这个是布局用的
#include <QBoxLayout>
// 不加这个会报错，定义的变量
using namespace QtDataVisualization;
// 头文件还要把变量给定义上，方便后边改图的数据
QSurface3DSeries *series;
Q3DSurface *groupBox;
QSurfaceDataArray * dataArray;
// 这个写完，三维的结构就有了
groupBox = new Q3DSurface;
groupBox->axisX()->setTitle("X轴");
groupBox->axisY()->setTitle("Y轴");
groupBox->axisZ()->setTitle("Z轴");
groupBox->axisY()->setRange(-5,10);
groupBox->axisX()->setRange(-11,11);
groupBox->axisZ()->setRange(-11,11);
//将三维图与数据进行绑定
QSurfaceDataProxy * proxy = new QSurfaceDataProxy;
series = new QSurface3DSeries(proxy);
/// 这个就已经将数据和图绑定了，后边更改图数据时候，直接改series即可
groupBox->addSeries(series);
QVBoxLayout* vLayout = new QVBoxLayout();
// 还有这个地方，是将groupBox和vLayout绑定到一起，直接改groupBox,页面里面的三维图也会跟着改变的
vLayout->addWidget(createWindowContainer(groupBox));
ui->widget->setLayout(vLayout);
dataArray = new QSurfaceDataArray;
这块按照自己的三维数组的数据,x,y,z填入，但是QT三维图轴顺序和正常不一样，需要改下数据顺序。
墨西哥草帽数据
int N = 41;
dataArray->reserve(N);
float x=-10,y,z;
int i,j;
for(i = 1;i <= N;i++){
QSurfaceDataRow *newRow = new QSurfaceDataRow(N);
y = -10;
int index = 0;
for(j=1;j<=N;j++){
z=qSqrt(x*x+y*y);
if(z!=0)
z=10*qSin(z)/z;
else
z=10;
(*newRow)[index++].setPosition(QVector3D(x,z,y));
y=y+0.5;
*dataArray << newRow;
}
x=x+0.5;
*dataArray<<newRow;
}
series->dataProxy()->resetArray(dataArray);
QSurfaceDataArray * dataArray_p = new QSurfaceDataArray;
//数据
int N = 73;//根据行进行设置
int M =73;//根据列进行设置
// 行列设置不好的话，图像会扭曲
dataArray_p->reserve(N);
int i,j;
for(i = 1;i <= N;i++){
QSurfaceDataRow *newRow = new QSurfaceDataRow(M);
int index = 0;
for(j=1;j<=M;j++){
//QT三维图绘制，轴并不是按照x,y,z这个顺序走的，具体怎么走的可以试试，中间是数据常规的z轴
(*newRow)[index++].setPosition(QVector3D(i,out_p[i][j],j));
*dataArray_p << newRow;
}
*dataArray_p<<newRow;
}
series_p->dataProxy()->resetArray(dataArray_p);
再放一个，数组好像是7272，还是7373，可以试试
dataArray->clear();
content_img->axisY()->setRange(min - min * 0.01, max + max * 0.01);
content_img->axisX()->setRange(0, N + 1 + 1);
content_img->axisZ()->setRange(0, N + 1 + 1);
// 按行列填数据
int NN = N + 1;
dataArray->reserve(NN);
for (int i = 1; i <= NN; i++)
{
QSurfaceDataRow *newRow = new QSurfaceDataRow(NN);
int index = 0;
for (int j = 1; j <= NN; j++)
{
(*newRow)[index++].setPosition(QVector3D(i, out_h[i][j], j));
*dataArray << newRow;
}
*dataArray << newRow;
}
// 更新数据
series->dataProxy()->resetArray(dataArray);
ui->bottom_console->appendPlainText(QString("气膜厚度 最大值: %1,最小值: %2.").arg(max).arg(min));
设置渐变
QLinearGradient gr;
gr.setColorAt(0.0, QColor(247, 41, 0));
gr.setColorAt(0.25, QColor(212, 168, 0));
gr.setColorAt(0.50, QColor(12, 235, 13));
gr.setColorAt(0.75, QColor(0, 134, 212));
gr.setColorAt(1.0, QColor(174, 15, 245));
content_img->seriesList().at(0)->setBaseGradient(gr);
content_img->seriesList().at(0)->setColorStyle(Q3DTheme::ColorStyleRangeGradient);
设置曲面样式
series_p->setDrawMode(QSurface3DSeries::DrawFlags(2));
如果ui文件更改了，编译却没有更新，重新构建将出问题的这个ui_widget.h备份后删除，并将之前编译产生的release/debug文件夹以及.pro.user文件都删除，然后重新打开qt，清理项目，重新qmake。
数据用自己的数据绘制就好，数据不太方便展示，就拿墨西哥草帽展示吧，
这种不全的情况就是范围给小了，设定范围要比值稍微大一点点，就可以了，
groupBox_h_3D->axisY()->setRange(-5,10);
groupBox_h_3D->axisX()->setRange(-11,11);
groupBox_h_3D->axisZ()->setRange(-11,11);
这个是后加的，头文件加的东西都在上边，下边代码我是写在mainwindow构造函数里面的
groupBox = new Q3DSurface;
groupBox->axisX()->setTitle("X轴");
groupBox->axisY()->setTitle("Y轴");
groupBox->axisZ()->setTitle("Z轴");
groupBox->axisY()->setRange(-5,10);
groupBox->axisX()->setRange(-11,11);
groupBox->axisZ()->setRange(-11,11);
//将三维图与数据进行绑定
QSurfaceDataProxy * proxy = new QSurfaceDataProxy;
series = new QSurface3DSeries(proxy);
groupBox->addSeries(series);
//将三维图在组中显示，布局如果需要的话，在添加一个 #include <QBoxLayout>
QVBoxLayout* vLayout = new QVBoxLayout();
vLayout->addWidget(createWindowContainer(groupBox));
ui->widget->setLayout(vLayout);
dataArray = new QSurfaceDataArray;
int N = 41;
dataArray->reserve(N);
float x=-10,y,z;
int i,j;
for(i = 1;i <= N;i++){
QSurfaceDataRow *newRow = new QSurfaceDataRow(N);
y = -10;
int index = 0;
for(j=1;j<=N;j++){
z=qSqrt(x*x+y*y);
if(z!=0)
z=10*qSin(z)/z;
else
z=10;
(*newRow)[index++].setPosition(QVector3D(x,z,y));
y=y+0.5;
*dataArray << newRow;
}
x=x+0.5;
*dataArray<<newRow;
}
series->dataProxy()->resetArray(dataArray);
执行代码
然后开始写按钮事件，比较简单，看下意思，类比一下就好了
void MainWindow::on_pushButton_clicked()
{
// 这个clear是必写的，写在开头，把dataArray数据清一下，不然很容易程序异常退出，还不好找问题
dataArray->clear();
// 这个地方是更改图的尺寸，就上面说的，已经绑定在一起了，直接改就可以了
groupBox->axisY()->setRange(-5,300);
// 这块的数据就假装换了吧，重新给series换下数据
int N = 41;
dataArray->reserve(N);
float x=-10,y,z;
int i,j;
for(i = 1;i <= N;i++){
QSurfaceDataRow *newRow = new QSurfaceDataRow(N);
y = -10;
int index = 0;
for(j=1;j<=N;j++){
z=qSqrt(x*x+y*y);
if(z!=0)
z=10*qSin(z)/z;
else
z=10;
(*newRow)[index++].setPosition(QVector3D(x,z,y));
y=y+0.5;
*dataArray << newRow;
}
x=x+0.5;
*dataArray<<newRow;
}
series->dataProxy()->resetArray(dataArray);
}
执行，然后点击按钮
基本上修改图的数据和结构就没问题了，剩下的就根据需要填数据和更改图的信息了。

我正在学习如何使用Nokogiri，根据这段代码我遇到了一些问题:require'rubygems'require'mechanize'post_agent=WWW::Mechanize.newpost_page=post_agent.get('http://www.vbulletin.org/forum/showthread.php?t=230708')puts"\nabsolutepathwithtbodygivesnil"putspost_page.parser.xpath('/html/body/div/div/div/div/div/table/tbody/tr/td/div
我有一个Ruby程序，它使用rubyzip压缩XML文件的目录树。gem。我的问题是文件开始变得很重，我想提高压缩级别，因为压缩时间不是问题。我在rubyzipdocumentation中找不到一种为创建的ZIP文件指定压缩级别的方法。有人知道如何更改此设置吗？是否有另一个允许指定压缩级别的Ruby库？ 最佳答案 这是我通过查看rubyzip内部创建的代码。level=Zlib::BEST_COMPRESSIONZip::ZipOutputStream.open(zip_file)do|zip|Dir.glob("**/*")d

很好奇，就使用rubyonrails自动化单元测试而言，你们正在做什么？您是否创建了一个脚本来在cron中运行rake作业并将结果邮寄给您？git中的预提交Hook？只是手动调用？我完全理解测试，但想知道在错误发生之前捕获错误的最佳实践是什么。让我们理所当然地认为测试本身是完美无缺的，并且可以正常工作。下一步是什么以确保他们在正确的时间将可能有害的结果传达给您？ 最佳答案 不确定您到底想听什么，但是有几个级别的自动代码库控制:在处理某项功能时，您可以使用类似autotest的内容获得关于哪些有效，哪些无效的即时反馈。要确保您的提
假设我做了一个模块如下:m=Module.newdoclassCendend三个问题:除了对m的引用之外，还有什么方法可以访问C和m中的其他内容？我可以在创建匿名模块后为其命名吗(就像我输入“module...”一样)？如何在使用完匿名模块后将其删除，使其定义的常量不再存在？ 最佳答案 三个答案:是的，使用ObjectSpace.此代码使c引用你的类(class)C不引用m:c=nilObjectSpace.each_object{|obj|c=objif(Class===objandobj.name=~/::C$/)}当然这取决于

关闭。这个问题是opinion-based.它目前不接受答案。想要改进这个问题？更新问题，以便editingthispost可以用事实和引用来回答它.关闭4年前。Improvethisquestion我想在固定时间创建一系列低音和高音调的哔哔声。例如:在150毫秒时发出高音调的蜂鸣声在151毫秒时发出低音调的蜂鸣声200毫秒时发出低音调的蜂鸣声250毫秒的高音调蜂鸣声有没有办法在Ruby或Python中做到这一点？我真的不在乎输出编码是什么(.wav、.mp3、.ogg等等)，但我确实想创建一个输出文件。
我在我的项目目录中完成了compasscreate.和compassinitrails。几个问题:我已将我的.sass文件放在public/stylesheets中。这是放置它们的正确位置吗？当我运行compasswatch时，它不会自动编译这些.sass文件。我必须手动指定文件:compasswatchpublic/stylesheets/myfile.sass等。如何让它自动运行？文件ie.css、print.css和screen.css已放在stylesheets/compiled。如何在编译后不让它们重新出现的情况下删除它们？我自己编译的.sass文件编译成compiled/t
我想将html转换为纯文本。不过，我不想只删除标签，我想智能地保留尽可能多的格式。为插入换行符标签，检测段落并格式化它们等。输入非常简单，通常是格式良好的html(不是整个文档，只是一堆内容，通常没有anchor或图像)。我可以将几个正则表达式放在一起，让我达到80%，但我认为可能有一些现有的解决方案更智能。 最佳答案 首先，不要尝试为此使用正则表达式。很有可能你会想出一个脆弱/脆弱的解决方案，它会随着HTML的变化而崩溃，或者很难管理和维护。您可以使用Nokogiri快速解析HTML并提取文本:require'nokogiri'h
我想为Heroku构建一个Rails3应用程序。他们使用Postgres作为他们的数据库，所以我通过MacPorts安装了postgres9.0。现在我需要一个postgresgem并且共识是出于性能原因你想要pggem。但是我对我得到的错误感到非常困惑当我尝试在rvm下通过geminstall安装pg时。我已经非常明确地指定了所有postgres目录的位置可以找到但仍然无法完成安装:$envARCHFLAGS='-archx86_64'geminstallpg--\--with-pg-config=/opt/local/var/db/postgresql90/defaultdb/po
