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 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. Wiki and useful External Resources on Computer Graphics.
