Hi, I'm drafting a blueprint [1] for simulation of deformations caused by water. What I want to see is something like [2]. I've been trying to achieve it with the envelope effect to no avail, because only the borders can be bent. Photoshop has a tool [3] closer to what I'm looking for.
I'm coming to the conclusion that one way would be to deform paths pulling the vertex and intersections of a grid. Now, if my memory is right, we had something like this some time ago but I don't recall its name and is not on the LPE menu on the latest revisions (maybe it was pulled?).
Suggestions about how to achieve the water waves effect are welcome. I'm trying to generate a sample of what I'm looking for, but so far inkscape is not helping me with the envelope LPE so I will probably have to resort to manual editing. One of my ideas is to use the named "grid" LPE and plug a list of sub-effects like ripple effect, water waves, horizontal waves, vertical waves... Each mode would present a set of settings, for example: * Ripple: freq, amplitude, position of the generator... * Waves: frequency, amplitude, randomness... * H/V waves: frequency and amplitude...

Hi, There is an experimental LPE called "Lattice Deformation". It is hidden by default because it sometimes ends with something unstable.
If you compile Inkscape, you can test it by uncommenting #define LPE_ENABLE_TEST_EFFECTS in src/live_effects/effect.cpp (line 9). As far as I remember, this LPE was sort of stable with shapes that were not too narrow. This can be explained because myself and the students that worked on it didn't understand very well of the inner data structure and its operations.
I think that your effect could be acheived with this kind of LPE. Today there are only 16 control handles, this could be parameterized in the future.
