Hello list,
Long time, no e-mail.
It seems there's a limit in [plot] to only plot the first 1000 elements of a struct's array (at least for me on Ubuntu 18.04, pd 0.51)? I was wondering if there was a practical and/or performance-related reason to that limit (and also if said limit could be raised).
I might have a weird use case, but I've been building a video player with 16-parameter biometric data associated with each frame so I've been using arrays in [struct]s to store the data and [plot] to plot it all out with a cursor drawn with [drawpolygon] to track the position in the data with the current video position. I've been working with up to 10-12ish minute long videos so that's arrays of about length 11000 with 16 elements per entry each and so I've been breaking the data up into 1000-element to get around that 1000 element limitation.
On my 5-ish year old laptop and loading up the data from a text file and plotting everything and togglinng and untoggling plotting certain parameters, the performance isn't so bad, definitely usable (just end up with a horizontally loooong canvas that you have to navigate with a fair bit of scrolling).
Hi Derek -
Pd hasn't ever been carefully tested in cases where objects send huge atomic messages to the gui - but in looking at teh code I don't see that there are any limits to their size (there used to be fixed buffer sizes here and there but it looks like it's all fixed now). So if you want, you can just remove the size limitations in g_template.c and recompile.
I'm scared to do this in the Pd release since I don't really know how to know whether it will really work robustly on all posible OSes etc.
cheers Miller
