Helix Toolkit 3D for .NET

Release 2.10.0

[2.10.0] - 2019-11-10

Added

  1. Added HelixToolkit.Core.Wpf nuget package to support .net core 3.0 WPF.
  2. Added HelixToolkit.SharpDX.Core.Wpf nuget package to support .net core 3.0 WPF.

Improvement and Changes

  1. Upgrade to use Visual Studio 2019 (Required by .net core 3.0).
  2. Upgrade minimum Windows SDK version to 10.0.17763 on shader builder project. (Required by Visual Studio 2019).

  1. Fixed single point hit test in SharpDX version #1225. (WPF.SharpDX/UWP/Core)
  2. Fixed nuget dependencies not getting installed. (WPF.SharpDX/UWP/Core)
  3. Fixed wrong distance comparison on mesh hit test. (WPF.SharpDX/UWP/Core)

Release 2.6.1

[2.6.1] - 2019-02-16

Added

  1. Flat Normal Shading Mode for Phong/PBR/Diffuse Material. Use EnableFlatShading = true to enable this mode.(WPF.SharpDX/UWP/Core)
  2. Add LimitPFS option to prevent FPS over shoot on mouse move (WPF)
  3. ManipulationBinding allows to map ManipulationGesture for Wpf.SharpDX (WPF.SharpDX)
