Ogre 3D 1.7

Time for action — adding a compositor

This is going to be our first compositor. We will use the scene and prepare to see its effect.

1. We need a new material for this, which does nothing at the moment. Add this new material in the material file that we previously used and name it Ogre3DBeginnersGuide/Comp1:

   material Ogre3DBeginnersGuide/Comp1
   {
   technique
   {
   pass
   {
   texture_unit
   {
   }
   }
   }
   }
   

2. Next, create a new file for storing our compositor scripts. In the same directory as the material file, create a file named Ogre3DBeginnersGuide.compositor.
3. In this file, define our compositor using the same scheme as we did for materials:

   compositor Compositor1
   {
   technique
   {
   

4. Next, define a target where our scene is rendered to before we can modify it:

   texture scene target_width ...
