Water ripple filter

The code should be in Execution box. The second image looks good.

Allright so i want the filter to be treated like a rectangle with perspective transformation. how would i get that effect?

If you still do not see any ripple effect it might be because your image is too small and the heightmap is uniformly black black in the upper left corner. The first mentioned file was a normal-map and Blender.OpNormalDisplace should be used instead of Blender.OpHeightDisplace with that (bluish) file.

I do not understand what you mean be the last sentence with the perspective transformation.

Oh god sorry i completely failed there. I didn't know i had to have my image already selected and then hit custom operation.

And one more thing, how can i save the custom operation for use later?

If you work with the custom operation, then just saving the code in a text file is OK. But you can also right-click on the toolbar and then duplicate the custom operation or another of them and re-configure it. It is also possible to export them from the configuration window.

Alright i got it working go check out the flickr page for the result.

The distorted reflection looks very good. Now I understand what you meant by the perspective. It would be hard to get a proper perspective correct water wave distortion effect - that would be a task more easily done with a 3D scene.

Hi Vlasta

Look at this example of ripples, it's a link to download a private p2p programme, and once installed, click the info button & run the pointer accross the RetroShare logo.

http://retroshare.sourceforge.net/

p.s., apart from good ripples & tetris, RetroShare's a really good private sharing network 😉 You can also get sourcecode. Hope this is of some help 😊

I have a neat little water filter custom operation button in my program now 😎
