I am developing LV tools to process and display data from a laser scanning system. Data comes into LV as a serial stream of SGLs, and there's some LV code to organize that serial stream into image lines, and then display it on the front panel.
There are two modes of operation...one in which an entire frame is decoded and displayed, and another that operates in a manner similar to a waterfall or cascade plot, where each new line (or groups of lines) is added to one end of the image, while old lines are popped off the other end.
The sample (pixel) rate, the scanner (line) rate, and the number of lines I wish to display determines the size of the 2D array I feed to the Intensity Graph front panel object. These front panel objects seem to have a non-trivial overhead associated with them...essentially limiting the frame display rate, or line display rate (depending on the mode of operation).
It seems that there's probably a more efficient way to display my image to a front panel that circumvents the Intensity Graph object, but I don't know what it is...which leads me to this section of the forum.
Are there LV Machine Vision vi's that might be better 'tuned' for writing intensity images to the front panel?
Is there LV hardware where I could just write data to a hardware buffer directly and have the output display on a separate monitor...free of Front Panel overhead?
