Change Log

All notable changes to this project will be documented in this file.

[2.22.0]

Improvement

  1. Change SceneNode.Attach to accept IEffectsManager instead of IRenderHost. This change will allow scene graph to be built and pre-attached in separate thread (all graphics resources are created during attaching). UI thread is still required to add generated sub graph back to the main graph which is associated with the Viewport. Example can be found here. (WPF.SharpDX/UWP/Core/WinUI)
  2. Re-implement logging to use Microsoft.Extensions.Logging.Abstractions logging interface. To override the internal debug logger, set HelixToolkit.Logger.LogManager.Factory on app start up to provide your own logging implementation.
  3. Due to logging change, minimum dot net version has been changed for all Helixtoolkit libraries. 
    + .Net Framework 4.6.2 
- .Net Framework 4.5
+ netstandard 2.0
- netstandard 1.3

Fixed

  1. Fix intersecting hit test in CrossSectionMeshGeometryModel3D. (WPF.SharpDX/UWP/Core/WinUI)

  2. Remove unnecessary scene graph re-creation during loading/unloading. (UWP/WinUI)
  3. Update WinUI AppSDK to 1.1.1. (WinUI)

Fixed

[2.2.0] - 2018-6-17

Added

  1. Add per-frame draw call in RenderDetail.
  2. Add pingpong buffer for post effects. Add depth stencil buffer pooling
  3. Add RenderTechnique serialization/deserialization.
  4. Add BlendFactor/SampleMask/StencilRef in ShaderPassDescription.
  5. Port DynamicCodeSurface3D to SharpDX version.

Improvement and Changes

  1. Move FXAA before post effect.
Pre(such as shadow map)->Opaque->Particle->Transparent->FXAA->Post(post effects)->ScreenSpaced(ViewBox/CoordinateSystem).
  1. Change to use specific material for mesh shading technique change. Added DiffuseMaterial(Render DiffuseColor/DiffuseMap only), NormalMaterial(Render Normals as Color), PositionColorMaterial(Render Vertex Position as Color), VertColorMaterial(Render Per Vertex Color). Remove separated techniques for normal/position/color rendering. Merge these passes into default BlinnPhong techniques.
  2. Encapsulate D3D11.DeviceContext functions into DeviceContextProxy. Skip redundant state bindings/shaderpass bindings.
  3. Re-implement shader class.

Fixed.

  • Fixed and improved state object and shader resource proxy pooling.
  • Errors building project (FeatureLevel10 issue). #754 (WPF.SharpDX & UWP)
  • Inertia does not work correctly when camera has lefthand coordinate system #760 (WPF.SharpDX & UWP)

  • EnvironmentMap3D not working when using LeftHandSystem SharpDX #533 (SharpDX & UWP)

[2.1.0] - 2018-5-4

Improvement and Changes

  1. New architecture for backend rendering and shader management. No more dependency from obsoleted Effects framework. EffectsManager is mandatory to be provided from ViewModel for resource live cycle management by user to avoid memory leak.
  2. Many performance improvements. Viewports binding with same EffectsManager will share common resources. Models binding with same geometry3D will share same geometry buffers. Materials binding with same texture will share same resources.
  3. Support basic direct2d rendering and layouts arrangement. (Still needs a lot of implementations)
  4. No more HelixToolkit.WPF project dependency.
  5. Unify dependency property types. All WPF.SharpDx model's dependency properties are using class under System.Windows.Media. Such as Vector3D and Color. More Xaml friendly.
  6. Post effect support. Note: Post effect elements does not recommend to be used in ModelContainer3DX for model sharing between viewports.
  7. Supports transparent meshes rendered after opaque meshes. IsTransparent property is added in MaterialGeometryModel3D.
  8. Rendering order by RenderType flag:
    Pre(such as shadow map)->Opaque->Particle->Transparent->Post(post effects)->ScreenSpaced(ViewBox/CoordinateSystem).
  9. Core implementation are separated from platform dependent controls(Element3D) into its own Scene Node classes. Scene Node serves as complete Scene Graph for traversal inside render host. Element3D will only be used as a wrapper to manipulate scene node properties from XAML.
  10. Supports Order independent transparent(OIT) rendering.
  11. Supports FXAA. Prefer FXAA over MSAA if using OIT or post effects. Note: FXAA does not support transparent background for now.
  12. High performance static octree for Mesh/Point/Line/Instancing Models hit test.
