Using Jitter to store numerical data
Storage of large quantities of numerical data is exactly what Jitter is for. You might commonly think of the data in Jitter matrices as representing pixels of a video image, but in fact you can use the jit.matrix object to store any large sets of (multi-dimensional arrays of) numbers, which can be used for any purpose.
Here’s an example of storing and playing back one minute’s worth of 18 xyz coordinates (for GL objects in 3D space, for example) at 30 fps. For simplicity, this example uses the random object to generate the numbers, but that could be replaced by any algorithm you want.
When you turn on the toggle labeled "record", the counter and uzi objects generate setcell messages to store a number in each plane of each cell of the jit.matrix object. This will generate 18 sets of 3 numbers for each of 1800 frames, presumably to be rendered in GL (not pictured here). The righthand part of the patch shows how you could read back those stored numbers. The jit.spill objects are included here just to show how you could parse and output the coordinates.
