Progress Report ~5

• Almost finished writing the dissertation introduction.
• I have managed to implement an edge detecting blur. It is not a completely accurate implementation, mathswise, but it is low cost. 
• Have started working on the global illumination aspect - I have looked at screen space radiosity techniques and implemented a simple local radiosity effect in screen space. This is essentially using the same ssao calculation but also taking into account scene colours (which are rendered into a half screen size texture).
• Next I plan to go over the SSDO paper in detail, both for my lit review and to develop more ideas for the GI aspect.
