I would like to use jitter / gen to create a mesh with only the white pixels of an image stored in a matrix (3 planes float32).

I would like to be able to separate these white pixels from the other ones (using another shorter matrix for example) then I would like to connect each of them to another one chosen randomly using a line.

I don't think it's possible using gen to ouput a matrix with a different dimension on each bang depending on the amount of white pixels found in a matrix (3 planes float32).

How can I find them and store them separetly then ? Or maybe there is another solution to draw line only between white pixels ?

your request is not really clear, please try to define better the final results you want to obtain.

Anyway for what i gather, you can have different solutions:

1. use xray.cellcoord and sift out the black pixels

2. use white pixels for z-displacement and black pixel to control alpha channel of the texture

3. look for some good rutt-etra simulations

Here is the result I try to obtain: The white line represents all the white pixels present in a matrix. The green lines represent the lines I want to draw randomly beetween theses pixels.

I have found another example, the first second of this video :

Hello, I tried with xray.cellcoord. I have removed all black pixels.

How can I do to create a mesh whith only the white pixel using jit.gen ?

Found it ! I needed the urn object to shuffle my matrices.
