...e following sections of this chapter, I will go over all the major components of each API relevant to the effect framework and give an overview of their use and function. Lets start by talking about some important tools to use in your effect development endeavors. And believe me, they will come in h...

...rue dynamic branching (determined through the hardware capability bits), the performance hit is the cost of the branch expression plus the cost of the instructions on the side of the branch taken. For this particular case, the task of optimizing shaders using dynamic branching is similar to optimizi...

...rdinates are respectively called tangent and binormal. Those vectors are de.ned as the 3D spatial direction in which the U and V texture coordinates are headed for a particular point on the surface. How to generate those vectors is outside the scope of this book, but be assured the D3DXMESH interfac...

You will also need to add the input parameters to the pixel shader main function, ps_main, so the interpolated normal and light direction can be read. With all those adjustments, you should end up with the following pixel shader:
