Radial Blurring / Feedback loops / Video Feedback

[Tetra]

Not sure of the process involved in a Radial Blur, but I gave it a go. I named it Fake Radial Blur:



http://www.tetrahedron.me.uk/FakeRadialBlur.zip - EXE and Code included

This one is made in blitz, not got FB installed atm.

Its a bit rough and slow, and by no means exact but it gives a similar effect and has a few parameters to change the look. There's also a couple optimization you can make if u used static Alpha values, and massive speed gain if u use a color pallet, rather than blending complete rgb values.
Mite be usefull to you as an alternative.

Thanks for the excellent explanation Optimus, I noticed the vague square in the centre of the screen of Keftedes but it was barely noticeable, a lot would depend on the effect it was being used with.
I'm going to be trying to do the effect myself in software before long.

Cheers for the source Rel, again you come up with the goods.

Last but not least, I couldn't believe my eyes when I saw a post from you here Tetra It's great that you're around and your radial blur looks pretty authentic to me

Cheers all, extremely helpfull. And I'll be concocting a few new prods with all this new info.

Humble thanks,
Clyde Radcliffe.

Tin Dragon: You'd have to supply the TGA texture yourself. :*)  Some of my posts have TGA's. or you could DL this and use the TGA file for the effect. :*)

Simple answer why it doesnt compile on some peoples machines, is that about 3 updates ago they did away with using the NOT command.

Thanks for the snippets dudes, one day I'll see about trying to convert the QBasic routine in Mono And Disco to FreeBasic. Still get probs with doing it.

Cheers and thanks,
Clyde.

DOH

Told you I never looked at the code, if I had would have spotted the need for a texture 

have that for not telling me sooner 

[relsoft]

hehehehe. remember to change the texture name. :*)

I've tried to transfer over the Feedback in mono and disco, to FB; and doing one myself. And im afraid im going to have to throw the towel in on this one. Thanks for all your time and help on this; I do appreciate it.

Thanks,
Clyde.

I dont suppose relsoft dude, you'd mind converting the Feedback part from Mono+Disco into FB. Just so that i can get the gist of it all please matey?

Cheers and many thanks,
Clyde

I'll see what I can do.  I'm doing some GL bloom and glow effects for the kart game though.

Ok mate, no hurry. And thanks so much dude.
