Ogre 3D 1.7

Time for action — complex compositor

We need a new compositor, material, and fragment shader:

1. The compositor script itself is nothing special. We need one texture for the scene and then directly use this texture as input for the output, which uses one material:

   compositor Compositor7
   {
   technique
   {
   texture scene target_width target_height PF_R8G8B8
   target scene
   {
   input previous
   }
   target_output
   {
   input none
   pass render_quad
   {
   material Ogre3DBeginnersGuide/Comp5
   input 0 scene
   }
   }
   }
   }
   

2. The material itself is also nothing new; just add a fragment shader like always:

   material Ogre3DBeginnersGuide/Comp5
   {
   technique
   {
   pass
   {
   fragment_program_ref MyFragmentShader8
   {
   }
   texture_unit
   {
   }
   }
   }
   }
   

3. Don't forget to add the definition of the fragment shader before using ...
