Ab3d.DXEngine v7.1.9105 change log:
- Added .Net 9 build of Ab3d.DXEngine.
- Implemented DynamicPlanarShadowRenderingProvider that can render soft planar shadow that is darker when the objects are closer to the shodow center position. The following additional objects are added: RenderDepthShadowRenderingStep, RenderDepthShadowPostProcess.
- Added VarianceShadowMaterial that can be used to render a material that shows only the shadow that is created by the VarianceShadowRenderingProvider - other parts of the material are transparent.
- Added UseVertexIdColor property to PixelEffect. It can be set to true to set the pixel color to the index of the pixel. This can be used to render the pixels to a bitmap and use that for hit-testing (the index of the pixel under the mouse can be get from the pixel's color). See new DXEngineHitTesting/VertexIdBitmapHitTesting sample for more info.
- Allowed using 2xSSAA (2x super-sampling) and 3xSSAA and not only 1x (no super-sampling), 4x, 16x and 64x. Using 2xSSAA increases the number of pixels by 2 and increases the width and height by 1.41 (=sqrt(2)). Using 2xSSAA already provides significantly improved line quality and is 2 times faster than 4xSSAA (requires 2 times less memory and 2 times less pixel shader invocations).
- Added OptimizedHighQualityHardwareRendering to GraphicsProfile. It uses 2xSSAA instead of 4xSSAA that is used by HighQualityHardwareRendering. Note that for backward compatibility, the default GraphicsProfile in DXViewportView is still HighQualityHardwareRendering. To use the new OptimizedHighQualityHardwareRendering, set the dxViewportView.GraphicsProfiles to new GraphicsProfile[] { GraphicsProfile.OptimizedHighQualityHardwareRendering, GraphicsProfile.NormalQualitySoftwareRendering, GraphicsProfile.Wpf3D };
- Added ShortArrowAnchor and ReverseShortArrowAnchor to LineCaps enum - it can render a short arrow at the start or end of the line.
- Added ToVector3Array and ToPoint3DCollection extenstion methods to easily convert from WPF's Point3DCollection and Vector3 array.
- Added FilterEffectTypeFunction to RenderObjectsRenderingStep. It can be used on custom RenderObjectsRenderingStep to prevent rendering objects with the specified effect type.
- Add support for chaning FilterSize on SeparableKernelPostProcess and derived classes (GaussianBlurPostProcess, DownSampleWithFilerPostProcess) after it was initialized.
- Setting DXAttributes.IsCastingShadow and DXAttributes.IsReceivingShadow (calling Visual3D.SetDXAttribute method) on Visual3D now sets that DXAttribute to all child Model3D objects. This way it is possible to disable shadow rendering or receiving shadow on a group of 3D models.
- Added DisableWpfResizingOfRenderedImage to DXViewportView. It can be set to true to show slightly sharper rendered image (but requires to set UseLayoutRounding on Window or parent Grid to true otherwise image tearing can appear).
- Prevented "StartBackgroundWaiting was called but the DXScene is still waiting in background for previous frame to finish rendering..." exception.
- Prevented "childNode is already child of another SceneNode" exception that may happen when a SceneNodeVisual3D is added to the Children of a ContentVisual3D that was already initialized.
- Improved rendering line arrows for poly-lines and other connected lines that have very short line segments. The new version prevents lines arrows to be smaller than 2 times the line thickness. This can be controller by new static LineMaterial.MinLineStripArrowLength property. There is also a new static LineMaterial.MinLineListArrowLength property that controls that for individual lines and disconnected lines (by default it is set to 0).
- Added SetMinLineArrowLength and SetMaxLineArrowLength methods to ScreenSpaceLineNode. They can be used to set custom values for line arrows length instead of default values that are read from static LineMaterial.MinLineStripArrowLength and LineMaterial.MinLineListArrowLength properties.
- Prevented DirectX validation warning when using Screen Space Ambient Occlusion (SSAO) or NormalDepthEffect with a 3D scene that renders 3D lines with line caps (arrows).
- Fixed using the correct size when calling DXViewportView.RenderToBitmap without parameters and when super-sampling is used - using DXFinalPixelSize instead of DXRenderPixelSize.
- Added BlurRangeScale property to GaussianBlurPostProcess. It can be used to increase the blur amount (usually this can be achieved by bluring a smaller texture).
- Fixed changing FilterSize in GaussianBlurPostProcess after the the post-process was already used.
- Fixed moving RenderablePrimitive items to the correct RenderingQueue after the CustomRenderingQueue on WpfModelVisual3DNode has been changed after the initial set.
- Prevented showing render artifacts (usually as partially rendered image) that may occur on some devices when using shared texture (PresentationType == DirectXImage). This can be controlled by the new DXScene.IsCreatingFinalBackBufferCopy property.
