在3D模型上应用选择效果 [英] Applying a selection effect on 3D models

问题描述

大家好，我想在3D模型中添加选择效果，这样当我选择模型时，它会淡出另一种颜色，而取消选择它时，它应该又变回原来的颜色再次上色.我的想法是创建一个情节提要板，并在选择了某个模型后在故事提要板后面的代码中的某个位置启动，但是，我将如何指定实际的淡入淡出效果，例如从棕色变为红色?

Hi Guys

I want to add a selection effect to my 3d models so that when I select a model it fades to another color, and when deselecting it, it should fade back to it''s original color again. The idea I have is to create a Storyboard, and somewhere in the code behind start the Storyboard when a certain model is selected, but, how would I go about specifying the actual fade effect e.g brown to red?

推荐答案

您可以使用ColorAnimationUsingKeyFrames 进行此操作，如以下示例所示:

You could do this using a ColorAnimationUsingKeyFrames as in the following sample:

<Window

  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

  x:Class="FadeSample.Window1"

  x:Name="Window"

  Title="Window1"

  Width="640" Height="480">
  <Window

  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

  x:Class="FadeSample.Window1"

  x:Name="Window"

  Title="Window1"

  Width="640" Height="480">
  <Window.Resources>
    <Storyboard x:Key="OnClick1">
      <ColorAnimationUsingKeyFrames 

        BeginTime="00:00:00" Storyboard.TargetName="button" 

        Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)">
        <SplineColorKeyFrame KeyTime="00:00:01" Value="#FFEF1407"/>
      </ColorAnimationUsingKeyFrames>
    </Storyboard>
  </Window.Resources>
  <Window.Triggers>
    <EventTrigger 

      RoutedEvent="ButtonBase.Click" SourceName="button">
      <BeginStoryboard Storyboard="{StaticResource OnClick1}"/>
    </EventTrigger>
  </Window.Triggers>

  <Grid x:Name="LayoutRoot">
    <Button 

      HorizontalAlignment="Left" 

      VerticalAlignment="Top" 

      Content="Button" 

      RenderTransformOrigin="3.339,5.055" 

      Margin="120,115,0,0" 

      Background="#FFDF891A" 

      x:Name="button"/>
  </Grid>
</Window>
