Hi all,
I just committed a new LPE: Interpolate. Does something like the python interpolate effect.
You can also draw the interpolation trajectory: the path along which the intermediate paths are drawn.
1. Draw a path consisting of 2 subpaths. (draw a line, then draw another line while holding shift. the 2nd line will be added to the 1st, the result will be an SVG path with 2 subpaths) 2. Apply LPE Interpolate.
The reason I made this interpolation between the 1st and 2nd subpath is that it seemed relatively easy to do this, instead of interpolating between whole sets of paths. Hmm, now that I think of it, it isn't all that much more effort actually. In any case, the UI is much easier to work with for subpaths than for 2 paths.
I could also do this probably: 1. Draw an interpolation trajectory 2. Apply LPE 3. Copy-paste first path as "Path A" parameter Copy-paste second path as "Path B" parameter
Let me know what you all think is best, maybe we want both, as in the case of bend path and pattern-along-path. ("Interpolate subpaths" and "Interpolate along path")
:) Johan
P.S. The LPE choose dropdown box is getting really huge now. Who wants to make mockups of what is a better system for applying effects?

I think that since we won't be able to interpolate style anyway, it's better to keep it to between subpaths, so it's analogous to Stitch subpaths. It's easier to edit in Node tool as well.

What about just a hierarchical menu with submenus, similar to the Effects menu?

I think we need a bit of a Big Picture (c)(R)(tm) here :)
We are likely to end up with a huge amount of LPE. If you have a loot at GIMP's Filters menu, it's overpopulated and difficult to navigate.
nip2 [1] developers solved similar issue by introducing search for filters. That's also what GIMP people are doing in one of this year's GSoC projects [2].
Should we be moving in that direction?

It would seem that a short-term menu system is better than a mess, though in the long run something better is probably good and necessary.

Problems...
A) If you select one of the paths via node tool and move, it affects the output, but doesn't adjust the position of the path. B) Ties into A, to move the end paths you must move the ends of the interpolation line. C) A small circle to a big circle (or vice-versa) equals wonky output (not perfect circles between). This does not happen with the python effect.

This is the way it should be IMO. Compare with how the bend path LPE works. While it is possible to switch things around such that moving the trajectory will do nothing, and one can move the subpaths for result; I think I prefer it the way it is now, but I am not an artist (and unlikely to use this lpe anyway). I think it should be the same like bendpath behaves (and other LPEs that I am forgetting).
C) A small circle to a big circle (or vice-versa) equals wonky output (not perfect circles between). This does not happen with the python effect.
Can you send me a file? I am seeing nice circles.

For the record, the bend path stuff has irked me since it was introduced too. ;) With that it's mainly the lack of ability to "reposition" the bend line if the orientation was incorrect on an object. The only way to achieve it is to edit the original path to line up with the "bend" path as needed (which is imprecise and time consuming). Not a major gripe, but there should be some method that is more user-friendly and obvious.
Another RFE for interpolation... some way to handle interpolated object orientation. If I start with two objects horizontally aligned it lines up the interpolated objects in a "flat" way along the trajectory line. If I curve the trajectory line, they retain the flat orientation rather than follow the line. If there was an option to let the objects follow the trajectory line as opposed to retain the original orientation it would make interpolate much more powerful. For reference, see the original screenshot I sent you (before you worked on this lpe).
As for circle imperfection, it wouldn't reproduce this time in quick way, but I have rectangles for you! ... example file attached.
