So, perusing teh internets once again, looking for something interesting to play around with, I came across this blog post of Pavan Podila (from 2008!). In the post, Pavan presents a WPF pixel shader which warps an image using bezier curves. I thought I’d have a go and reproduce the effect in AGAL and plunk it into a Starling filter. Essentially, the filter adds 8 control/anchor points to the filtered display object – 4 on the left edge and 4 on the right. You can move those points from 0 (far left) to 1 (far right) and the image will warp and curve to fit those points. You can check out the end product here. In theory, with a little patience and finesse, you could animate those points to create a nice looking Mac style genie effect. Or, whatever.
As I was working on that filter, though, I realized I had a decent sized Starling filter collection built up and spread out all over the shop. For that reason, I decided to put them all together and upload them to Github. So, now, you can download all the filters I’ve posted about (and one or two that I haven’t), including the Warp Filter demonstrated here, over on Github.
When I get some time, I’ll upload some tests to make it easy to see what each one can do. In the meantime, though, you’re welcome to have at, as is.
Enjoy.
Is there a way I can rotate this filter so that it goes verticle instead of horizontal?
Hi,I very like your Warp Filter for Starling,i’ve checked out your products and downloaded Starling-Filters ,but it just a Source Code,i don’t how to use it to mark a product like you.Would you mind telling me how it works ? thinks.
Great filters… can’t get them to work though – keep getting the following error when I try to instantiate them.
Error: Error #3615: AGAL validation failed: Program size below minimum length for fragment program.
Any help would be greatly appreciated.
Hey Daniel,
Sounds like it may be an unsupported Context3D Profile. Try using baseline or even baseline extended rather than baseline constrained (if that’s what you’re using).
Hi and thanks for your work, but do you know why I get
warning: bad line 0:
warning: bad line 1: mov ft0, v0
and finally the Error
[Fault] exception, information=Error: Error #3615: AGAL validation failed: Program size below minimum length for fragment program.
When I try to use one of your filters?
Thanks!
