GPU Motion Blur effect using DirectCompute

Recommended Posts

When you say "Motion Blur", What's the kernel you use?

Simple averaging in a direction?

I would like to try it on CPU.

I'll try to give results later.

Update:

Ok, got some results.

This is the configuration:

Q8200 @ 2100MHZ

4GB Memory.

nVidia GTX460

1280 x 960 - Matlab

BlurringKernel = fspecial('motion', length, 25)

Time:

Length = 50 - 0.29 s

Length = 100 - 0.9 s

Length = 200 - 5.5 s

uTorrent and Chrome on background.

Matlab is maybe as fast as it gets in those calculations (CPU).

So your results are nothing but stunning.
