c# - How to change ViewPort3D background color in WPF? -

-

i have viewport3d , want change background color.

i new wpf. didnt understand other posts. ask here.

i changed brush property viewport3d nothing

<window x:class="w3dtinker.mainwindow"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     title="mainwindow" height="800" width="1200"> <grid horizontalalignment="left" height="780" margin="10,10,0,-21" verticalalignment="top" width="1180">     <viewport3d grid.row="0" grid.column="0" x:name="viewport" margin="350,10,10,10" opacitymask="{dynamicresource {x:static systemcolors.appworkspacebrushkey}}" /> </grid>

viewport3d control creates 3d scene render things into. not display itself. if want background color behind it, set background color on parent control, in case grid contains it.
