.NET6 开发基于WPF的摩登三维工业软件

前言

一、 设置暗黑主题

利用MergedDictionaries配置，在已有的通用风格基础上添加Dark.Blue主题。代码如下：

< Application.Resources>

< ResourceDictionary>

< ResourceDictionary.MergedDictionaries>

< ResourceDictionarySource= “pack://application:,,,/Fluent;Component/Themes/Generic.xaml”/>

< ResourceDictionarySource= “pack://application:,,,/Fluent;component/Themes/Themes/Dark.Blue.xaml”/>

</ ResourceDictionary.MergedDictionaries>

</ ResourceDictionary>

</ Application.Resources>

运行一下：

主题已经变成了暗黑模式。

二、给Button增加图标

2.1、引入图片

在项目目录下增加Resources目录，把circle.png复制到Resources目录下。

在项目浏览器中把图片添加到项目，选择Resources目录，右键菜单：

选择Resources/circle.png

2.2、设置图片属性

选择图片，在属性面板中设置：

复制到输出目录：始终复制

生成操作：内容

按照上述步骤加入其他的图片。

2.3、Ribbon Button中使用图片

为Fluent:Button设置Icon属性，引用图片资源

<!–Tabs–>

< Fluent:RibbonTabItemHeader= “建模”>

< Fluent:RibbonGroupBoxHeader= “基本体”IsLauncherVisible= “False”>

< Fluent:ButtonHeader= “直线”Icon= “/Resources/line.png”Size= “Large”/>

< Fluent:ButtonHeader= “圆弧”Icon= “/Resources/arc3pts.png”Size= “Large”/>

< Fluent:ButtonHeader= “圆形”Icon= “/Resources/circle.png”Size= “Large”/>

</ Fluent:RibbonGroupBox>

</ Fluent:RibbonTabItem>

< Fluent:RibbonTabItemHeader= “设置”>

</ Fluent:RibbonTabItem>

运行一下：

三、增加Button响应消息

3.1、增加路由命令

定义RoutedCommand用于响应Button的点击事件。MainWindow.xaml.cs

publicpartialclassMainWindow

{

// 定义路由命令

publicstaticreadonlyRoutedCommand ExecuteCommand = newRoutedCommand( “Rapid”, typeof(MainWindow));

publicMainWindow( )

{

InitializeComponent;

// 绑定响应函数

CommandBindings.Add( newCommandBinding(ExecuteCommand, OnExecuteCommand));

}

privatevoidRibbonWindow_Loaded( objectsender, RoutedEventArgs e )

{

}

// 处理点击命令

privatevoidOnExecuteCommand( objectsender, ExecutedRoutedEventArgs e )

{

}

}

3.2、XAML里绑定Button绑定事件

Command: 绑定的命令

CommandParameter: 命令参数

MainWindow.xaml

< Fluent:ButtonHeader= “直线”Icon= “/Resources/line.png”Size= “Large”Command= “{x:Static local:MainWindow.ExecuteCommand}”CommandParameter= “line”/>

< Fluent:ButtonHeader= “圆弧”Icon= “/Resources/arc3pts.png”Size= “Large”Command= “{x:Static local:MainWindow.ExecuteCommand}”CommandParameter= “arc”/>

< Fluent:ButtonHeader= “圆形”Icon= “/Resources/circle.png”Size= “Large”Command= “{x:Static local:MainWindow.ExecuteCommand}”CommandParameter= “circle”/>

3.3、命令处理函数// 处理点击命令

privatevoidOnExecuteCommand( objectsender, ExecutedRoutedEventArgs e )

{

switch(e.Parameter.ToString)

{

case“line”:

{

varshape = SketchBuilder.MakeLine( newGPnt( 0, 0, 0), newGPnt( 10, 10, 0));

mView3d.ShowShape(shape, ColorTable.AliceBlue);

}

break;

case“arc”:

{

varshape = SketchBuilder.MakeArcOfCircle( newGPnt( 0, 0, 0), newGPnt( 10, 10, 0), newGPnt( 5, 15, 0));

mView3d.ShowShape(shape, ColorTable.AliceBlue);

}

break;

case“circle”:

{

varshape = SketchBuilder.MakeCircle( newGPnt( 0, 0, 0), 5, GP.DZ);

mView3d.ShowShape(shape, ColorTable.AliceBlue);

}

break;

}

}

运行一下，挨个Button点一遍：

四、综合建模爱心巧克力

一种实现方法：

由线生成爱心平面轮廓

轮廓填充成面

面拉伸成体

对体倒角

{

vararc1 = SketchBuilder.MakeArcOfCircle( newGPnt( 0, 2, 0), newGPnt( 10, 0, 0), newGPnt( 5, 5, 0));

vararc2 = SketchBuilder.MakeArcOfCircle( newGPnt( 0, 2, 0), newGPnt( -10, 0, 0), newGPnt( -5, 5, 0));

varbottomPt = newGPnt( 0, -12, 0);

varline1 = SketchBuilder.MakeLine( newGPnt( -10, 0, 0), bottomPt);

varline2 = SketchBuilder.MakeLine(bottomPt, newGPnt( 10, 0, 0));

varshapeList = newTopoShapeList;

shapeList.Add(arc1);

shapeList.Add(arc2);

shapeList.Add(line1);

shapeList.Add(line2);

varwire = SketchBuilder.MakeWire(shapeList);

varface = SketchBuilder.MakePlanarFace(wire);

varshape = FeatureTool.Extrude(face, 5, GP.DZ);

shape = FeatureTool.Fillet(shape, 1);

mView3d.ShowShape(shape, ColorTable.PaleVioletRed);

}

五、总结

varmesh = FontManager.Instance.CreateMesh( “情人节快乐！”);

varmaterial = MeshPhongMaterial.Create( “love-material”);

material.SetColor(ColorTable.OrangeRed);

varshape = newPrimitiveSceneNode(mesh, material);

mView3d.ShowSceneNode(shape);
