Gets or sets a cached representation of the Viewport2DVisual3D.
Assembly: PresentationCore (in PresentationCore.dll)
Set the property when you need to increase performance for content that is time-consuming to render. For more information, see BitmapCache.
The Viewport2DVisual3D class projects 3-D content into 2-D to size the 2-D content in the 3-D element correctly.
Because caching always relies on the element’s size, instead of the transform applied to it, when you set the CacheMode property, initially your content may appear pixilated. This is because it is being upsampled to a much larger size than it was cached at. You can correct this situation by increasing the local size of your 2-D visual by setting the Height or Width properties. Also, you can increase the RenderAtScale on the until the content reaches an acceptable level of clarity.
