In this part you will be studying screen-space post-processing.
The post-processing goal is divided into two tasks:
Edit the file 'fxstudio.ini' and set postprocessing to true. The application will now show the post-processing window.
Open ‘postprocessing.fx’ in a text editor of your choice, or double click the file in the solution view in Visual Studio under fxstudio/fx. The .fx file is physically located at:
(Working directory)/fxstudio/fx/
Familiarize yourself with the effect file, especially note how several render passes are used.
The post-processing step of this laboratory project operates using one or more rendering passes. For each pass the post-processing window copies the area of the frame buffer which it occupies and writes it to a texture. This texture is then used as input for a screen aligned quad to which the techniques of the effect file are applied.
Proceed to Task 3A when you are confident that you understand the mechanism used for screen-space post-processing in this project.
