Basic OpenGL 2D Screen Filters in the BGE - Part 3

Hey. This time, we'll be looking into something new - a blur filter! What? We did that already? Oh... Well... What if we controlled it with a VARIABLE?! EH?

OpenGL 2D Screen Filters in the BGE - Part 2

Hey. So, today, we'll take a look at another, slightly more complex 2D screen filter - the common Blur filter (yeaah!).

OpenGL 2D Screen Filters in the BGE - Part 1

Hey, there. So today, we'll look into using some simple GLSL (OpenGL Shading Language) functions with the Blender Game Engine to make some 2D screen filters. Theoretically, you could even implement this with other game engines to create 2D screen filters, even engines using other programming languages, like Microsoft's HLSL (High Level Shading Language).
