Motion Blur

effect

about

this reacts to world-, view-, projection-, aspect ratio transformation and dynamic meshes too.

the help patch is a bit lame but i hope that shows well how to use this.
have fun!:)

update:
i've done some minor fixes and cleanups and i solved the ugly edges by smoothing the velocity map. also i discovered that the blur of the movement on Z axis was incorrect when perspective was used so that's fixed too.

update2:
revamped the whole thing: now it's nicer and has more control. still it has some ghosts caused by the blur though.

update3:
added blur filter instead of the gaussianblur, added more control to velocitymaps, corrected this and that

update4:
i discovered after this long time that the direction of the blurring was not always right and it was annoying. so it's fixed now and it's way much nicer.

nice one, this was on my list for a long time.
i guess its based on this http://http.developer.nvidia.com/GPUGems3/gpugems3_ch27.html ??

maybe you find some missing piece in this document. the shader code in gpu gems looks a lot more concise. anyway, good work, microdee

great and useful contribution, thxxxxx :D

microdee 06/02/2011 - 14:41

yep it's partly based on that. however i was a bit surprised that the "for" cycle gave a syntax error in vvvv so i used this not really elegant method (i don't know much about it but this is a limitation of SM 3.0 or i overlooked something?)

hooray for new shader contributions! :)

good job microdee! :)
yes, a serious motion blur was needed and this seems really interesting! tnx!

thx

Wow, A little motion blur really does miracles!!

thx, like it.
in your dropbox.zip the shader "gaussianblurRatio" is missing.

microdee 07/02/2011 - 19:17

fixed in theory

help file not working with beta27.2
black screen, just the PIP rendering works.

same here

sorry i've done this in alpha28 and it was working there on b27.2 very weird stuff happens i confirmed black screen and alt + right click on Grid (EX9.Geometry) inside the Blend (EX9.Texture Mixer) fixed the problem. so now i've "extracted" blend.fx and it works without alt+rightclicking on grid

joreg: @karistouf there are no freeframes in x64 but you can use Contours via VL.OpenCV in VL!

karistouf: is there any contour.dll (FreeFrame) in x64 ? thank you

joreg: @qoupas i'm afraid this is a rather unspecific question. please start a forum thread with more details so we can help you.
