I am attempting to create an animation to a layer with Mathmap's erecterect plug-in:



After clicking on the animate checkbox, and setting the t to 0:




Setting the 'User Values' Pitch to 0:





Setting t to 1:




Finally changing the Pitch to 180 at 'User Values':




Should create a series of 10 frames, interpolating the initial with the final parameters chosen, however, I only obtain a repetition of the frame with the last values:



The next frame is the same




And so on...

There is no animation.

I am using Photocomix Lab installation.

I can see why there is no animation but I am not familiar with this plug-in you are using. You won't see any animation if all the frames are the same.
Did you try running it with just the default settings to see what happens?

Yes but the same happens, although if you leave the values unchanged, the same first frame(the one the plugin is called with) will be repeated, since no change was made.

Simple :
1) all the filters in the Animation menu may be animated
2) some other filters from other menu may be animated too , BUT not all on the contrary just a few

In case of filter that can't be animated that is the result, new layers are created but all identical

And yes in theory all MM filters may be animated but that require edit the code

Very weird error message, weird for the reference to "image.scm" ... sure a file with that name and extension inside MM may cause a error


The second is not more active the google group has no much activity but is still alive

In this case you may try to ask also on the "Panini" google group, because the author of the filter is the same of Panini:

That filter was 1 of several more or less experimental filters done to recreate a peculiar and very interesting type of mapping , the name derive from a Italian Painter that was using it very often

I believe that was one of the first version, then was more polished and improved and finally the author decided to create its own program that allow not only the Panini mapping but also many other types

So i am not sure how much may be interested now to correct a old and primitive version, also as MM script there are more advanced version (all with "panini" in the name )

As for the animation MM allow easily 1 type of animation ... basically apply a recursive curve , the limit is that this type of animation doesn't give much control to the user but is that easy to implement
... easy as include/add a "t" variable in the code
(2 examples Distort/Pond and Distort/Enhanced Pond )

Then is also possible another type of animation that allow to chose the values for the first and for the last frame and the other values will be interpolated:
This give much more control but is harder to write and also the interface of similar filters looks awful complex because all the commands need to be doubled ...so if a not animated filters has as example 8 sliders a version "animated" with this method will need 16 sliders
More while is clear how to get a preview for the "first frame" to get a preview for the "last frame" is needed a not too intuitive (and time wasting ) trick
(a example is Animation/Animated sphere )
