I did see the thread and did see TiAm's comment there, but he forgot to say a Some-thing three times <img src="{SMILIES_PATH}/icon_e_biggrin.gif" alt=":D" title="Very Happy">
Seriously, though, at least with my knowledge it feels like it wouldn't make too good a Shader - it would probably be possible to make something that simply fades out the previous frame for a Geometry-wars like effect, but "proper" motion blur is a little different.
One approach would be to make something like the racetrack Shader: https://dl.dropboxusercontent.com/u/132 ... index.html but with control over X and Y coordinates and sort-of sample the pixels instead of just shifting them (which is responsible for the graininess of that version). Something tells me it would be a "greedy" Shader, though. I'll add it to the list of potential Shaders.
Really cool! Good job!
Thanks! THe pace has slowed down a little, but more will come.
