// Sample of DirectX11 Tessellation Tutorial from www.xtunt.com

// This allows us to compile the shader with a #define to choose
// the different partition modes for the hull shader.

// See the hull shader: [partitioning(BEZIER_HS_PARTITION)]
// This sample demonstrates "integer", "fractional_even", and "fractional_odd"

// GLSL Control shader
