  1. Added AlwaysHittable property for scene nodes. Allow mesh to be hittable even it is not being rendered(Visable = false). Ref #1393 (WPF.SharpDX/UWP/Core)
  2. Implemented high DPI rendering under DPI scaling to improve rendering quality. #1404 (WPF.SharpDX/UWP/Core)

Improvement and Changes

  1. Improved small triangle hit test. Ref #1353 (WPF.SharpDX/UWP/Core)
  2. Supports up to 8 clipping planes(cross section). Ref #1396 (WPF.SharpDX/UWP/Core)
  3. Supports Dot Net Core 3.1. (Core)
  4. Upgrades Assimp.net to 5.0 beta.


  1. Fixed hit test in CrossSectionGeometryModel3D when uses octree or set CuttingOperation = Substract. Ref #1396 (WPF.SharpDX/UWP/Core)
  2. Fixed keybinding issue in Viewport3DX. Ref #1390 (WPF.SharpDX)
  3. Fixed UWP runtime error due to dependency property naming conflicts. #1365

    In order to fix the issue, following breaking changes have to be made: (UWP)

    • Transform3D renames to HxTransform3D. The Transform3D is a DP in UWP UIElement, which is not able to override.
    • Gesture bindings for UWP Viewport3DX have been moved into Viewport3DX.ManipulationBindings from Viewport3DX.InputBindings.
  4. Fixed small error in the calculation of the animation. #1405 (WPF.SharpDX/UWP/Core)
  5. Fixed typo in TextInfo. #1415 (WPF.SharpDX/UWP/Core)
