Display 360 lidar point in Jitter
Hi,
I'm using an ESP32 to send RPLIDAR S2 data to Max via OSC. I receive all the point data in pair, angle and distance. How can I draw each of these point in jitter so the new scan erase the old scan continuously? I did some test with LCD but it does not works very well. Can some help me with this one?
Thanks
to paint rectangle of 3x3 points, you must limit
output to jit.lcd size - 3 points.
0 - 317 and 0 - 237.
to insert fresh framerect, simply use t l clear
Hi,
Thanks for the reply, just realized I used "pak" instead of "pack". Now it works better for the display. About the "clear" I will make me self clearer : I have a stream of 3250 value by 360 degree scan. I want them all displayed at the same time, but never overlapping. So when it start a new scan, when I receive the new 0, I want the value 0 of the previous scan to disappear, when it receive the new value 1, I want the value 1 of the previous scan to disappear and so on, so there is always 3250 point on my display, like the refresh on a radar,
Is there a way?
then maybe use setpixel instead of frames.
Hey Elby,
it's much easier if you use openGL for rendering the dots:
Hi,
Thanks Matteo, this is way better! But are the points supposed to disappear? For now it is just accumulating forever. How can I can start clearing the points after the first 3250 point scan?
Never mind, my jit.world "erase_color" was set to 0 alpha... This is perfect thanks a lot!
