Save and recall the state of a matrix +index
I’d like to be able to output a matrix with jit.bfg (greyscale data, 8 planes) into another jit.matrix and then save the state of that jit.matrix as a preset.
Have multiple presets and be able to save and export this data. I saw that I can read and write a matrix file individually but I’d rather just do this with an index system so that everything is loaded at once.
I checked the forums but just can’t seem to find a solution.
And and all help would be greatly appreciated.
[jit.submatrix] might be your friend.
or fill a multislider with your matrix data and save the multislider state in your preset system… there is a good example Andrew benson’s receipes
jit.submatrix only allows you to sample a portion of a matrix not save it in any form.
I think using 8 multisliders for 8 planes of data would use way too much cpu than I’d need.
Any other solutions anyone ?
apologies i ment [jit.marixset] and not [jit.submatrix], my bad
i don’t know you can record 8 planes with [jit.qt.record] but with some workaround you could then read your matrices back as frames with a [jit.qt.movie] also…
you don’t specify the dimensions of your matrices ?
Sorry for the late reply.
I need to keep all 8 planes of data because I’m using them to distort and manipulate open GL models. so plane 1 is the x co-ordinate of a vertex, plane 2 the y co-ordinate (well thats the idea of it) This is why jit.qmovie won’t work as I’ll lose all the planes.
For now I’ve just used a sel object to bang a read message which loads the matrix state. This works, but I’d rather know if theres an index system or something else that I can use.
I tried jit.matrixset but this won’t work because I ned to load all the different matrices at start up.
The dimensions of the matrices don’t matter and vary according to each model that I load.

jit.matrixset has ‘write’ and ‘read’ messages that allow you to store and recall its contents in a file, just as you would do with most presets.
