I have created a multiscreen openGL patch with a character following the trajectory co-ordinates of a sound being encoded and dispersed by the ICST ambisonics externals.

I now need to take the information from one of the GL renderers to creat a low res matrix to generate a list of values to be sent to an arduino to control an LED matrix.

Has anybody any idea how I can reprocess an a jit.window as a jit.matrix?

Also if anybody could help me with converting the values of a matrix into a list for distribution to the arduino that would be great!

there are are many ways to readback from gpu to jit.matrix.

see for one the readback patch in the example folder (search for readback,

dono exact name). if your going more cutting edge try 40 recpies in andrew's

you should defently dimscale your slab before sending it back, you dont need

to read values from matrix you use jit.spill or jit.iter

third cookbook.

everything as i imagine.

create a small and simple patch demonstrating the problem and your likely to get more help.

Here is a simplified version of the patch

Cheers robtherich
Here is a simplified version of the patch

this is covered pretty well in the tutorials and the example patches.

matrixoutput sends the list of vertices that make up the geometric shape out the left outlet in matrix form. therefore if you connect this output to jit.window, you will see the colors you mentioned earlier. this is expected behavior.

what are you trying to accomplish with this list?

Downsample GL jit.window source to Jit.matrix?
