Potential Breaking Changes:

  1. Material UV Transform has been changed from Matrix to UVTransform struct. (WPF.SharpDX/UWP/Core)

(WPF.SharpDX/UWP/Core)
  3. GroupModel3D and ItemsModel3D will no longer support using XAML Children and ItemsSource at the same time (To be consistent with other WPF controls such as ListView).(WPF.SharpDX/UWP/Core)
  4. PBR material RMAMap property has been renamed and separated into RoughnessMetallicMap and AmbientOcclusionMap.
  5. AmbientColor in InstancingParams has been removed.(WPF.SharpDX/UWP/Core)
  6. Remove Core namespace on Vector3Collection/Vector2Collection/IntCollection. Base class is changed to FastList<T>.
