Time for action — adding a pulse

Adding a pulse to our model is quite easy and only needs some changes to our code.

1. This time, we only need a new vertex shader because we are going to use the existing fragment shader. Create a new vertex shader named MyVertexShader5 and use it in the new material MyMaterial17, but use MyFragmentShader2 because this shader only textures our model and nothing more:

   material MyMaterial17
   {
   technique
   {
   pass
   {
   vertex_program_ref MyVertexShader5
   {
   }
   fragment_program_ref MyFragmentShader2
   {
   }
   texture_unit
   {
   texture terr_rock6.jpg
   }
   }
   }
   }
   

2. The new vertex shader is the same as the ones we've seen before; just add a new parameter in the default_params block called pulseTime that gets the value from the time keyword:

   vertex_program ...
