drawing lines to a matrix from mxj efficiently ?
I don’t have time to answer your questions but a while ago on this list
I provided a really simple example of using mxj to draw to a jit matrix.
I think it was pretty efficient or at least efficient enough. I ended up
having real time audio buffer rendering without a hiccup.
Also. This I understand your concern with performance. I have similar
leanings. However, lets be clear about what 5 microseconds adds up to
called 30 fps.150 microsecs. 0.15 milliseconds. See,s acceptable to me.
People keep bringing up the bridge and believe me…the bridge is
probably never something to worry about. We are dealing with the bridge
at signal rate in mxj~ and it really isn’t a big deal.

Hi Emmanuel, hope everything goes fine for you,

thanks.. so where is this attachment now ?
It went through the mailing list, but not with the forum… here it is.
well, i think it’s not really what i’m looking for…
i think that i might put me into the "JitterMatrix BufferedImage" stuff to really draw lines… i found an example for that on the forum posted by Ignotus, and i’m going to look at it. (but if someone have an other example, why not)
i also have to read the color of hundreds of differents pixels coming from a matrix, this, for every little move of my pen on the wacom tablet (every 10 ms) (while the DSP audio is at 50% of CPU)
– copyMatrixToArray :
it seems that previous posts speak about crash problems with the "copyMatrixToArray(int data)" that would not be very stable. right ? i just managed to found the api-jitter in my old max 4 folder, but for now, i don’t really understand how the color data is transfered to the array. Any example for this would be greatly apreciated.
