Okay, I'll do some improvements in the next days but the shaders can already be used now.
You can download it
here (~1.51 MB)About the blur and the glow shader in general:
these shaders support HDRR, so you're not limited to the color range of 0 - 255. Use bright glow-colors to get a nice, bloomy effect.
Regarding the demo:
I've made 2 demos.
One showing the glow effect with the 2 cubes and one showing a neon-style effect (with graphics from the game 'GridWars')
have a look at 'main_cubes.c'.
In this file there's a lot of stuff explained and commented.
In the demos you can enable / disable the postprocessing with the p-key, move with wasd & mouse (hold right mouse
button to rotate the camera), use the zoom-blur effect by holding enter, and toggle the cubes rotation with the space-key.
EDIT: regarding your problem: it seems like the object is not using the shader.
Make sure you set the right material and .fx file
EDIT#2: in the example you uploaded the object-shader's file was called "glow.fx" or something like that. I chaged the name to "object.fx" maybe that's the problem
