exercise: toon shader

introduction to 3d game programming with dx11---chapter 7,exercise 3:

transforming Kd and Ks discrete functions like followingbefore using them in the pixel shader.

 1 void FuncD(in float d,out float Out)
 2 {
 3 if(d <= 0.0)
 4 Out = 0.4;
 5 else if(d > 0.0 && d <= 0.5)
 6 Out = 0.6;
 7 else if(d > 0.5 && d <= 1.0)
 8 Out = 1.0;
 9 }
10 void FuncS(in float s,out float Out)
11 {
12 if(s >= 0.0 && s <= 0.1)
13 Out = 0.0;
14 else if(s > 0.1 && s <= 0.8)
15 Out = 0.5;
16 else if(s > 0.8 && s <= 1.0)
17 Out = 0.8;
18 }
