Windows 10 SDK (Min Ver.10.0.18362.0).** ## Notes #### 1. Right-handed Cartesian coordinate system and row major matrix by default HelixToolkit default is using right-handed Cartesian coordinate system, including Meshbuilder etc. To use left-handed Cartesian coordinate system (Camera.CreateLeftHandedSystem = true), user must manually correct the triangle winding order or IsFrontCounterClockwise in raster state description if using SharpDX. Matrices are row major by default. #### 2. Performance [Topics](https://github.com/helix-toolkit/helix-toolkit/wiki/Tips-on-performance-optimization-(WPF.SharpDX-and-UWP)) for WPF.SharpDX and UWP. #### 3. Following features are not supported currently on FeatureLevel 10 graphics card: FXAA, Order Independant Transparent Rendering, Particle system, Tessellation. #### 4.
