| DeviceRemovedEventArgs |
DeviceRemovedEventArgs is used when the DirectX device is removed or reset.
The event handler can handle this case with saving the current state of the 3D scene, dispose the current DirectX objects and recreate the 3D scene.
|
| DXDeviceResourcesCache |
DXDeviceResourcesCache is used to store DXEngine's objects (WpfMaterial, DXMeshGeometry3D and WpfGeometryModel3DNode) that are created from WPF objects.
This allows reusing DXEngine's objects when one instance of WPF object is used on multiple objects - for example one DiffuseMaterial can be used on many GeometryModel3D objects.
This class caches objects per DXDevice and is set to the DXDevice's ResourcesCache property.
