byte-accuracy red, green, blue channels) = 27 bytes. More likely 28 bytes as colours are probably stored as 32-bit integers, allowing for an unused alpha channel.
28 * 800,000 equals roughly 22 megabytes, which is way down from 9 gigabytes. That's a 400 fold memory overhead, which is pretty hefty.
Grasshopper stores points as instances of classes, so on 64-bit systems it actually takes 64+64+3*8 = 152 bytes per point*, which adds up to 122MB, still way less than 9GB. It would be interesting to know where all the memory goes...
* Grasshopper points also store reference data, in case they come from the Rhino document. This data will not exist, but even so it will require 64-bits of storage.…

eone would know how to group each data position from each branch ... meaning, for instance, that I have a list of data with 3 branches, each branch containing 28 data instances (see attached image). Now, how would I get the (0;0)+(1;0)+(2;0) to be grouped in a new branch, as well as (0;1)+(1;1)+(2;1) and so on?
Also, I need for the setup to able to take in variables, so that the 3 branches might change to 6, and the 28 data instances might to change to anything between 10 and 100.
Thanks in advance,
/Claus

error message when GH starts loading (almost the last stage of loading).
I un-installed and re-installed it, but still the same error. When I checked the plug-ins in the options, it seems that it is loading the right one (from the file path), but I noticed when GH starts loading, it is loading GH version Sep 28, 2012.
Any idea how I can get around this problem?
thanks

t item (see the image), is it possible to do this in another way (quickly) ?
Is it possible to divide that curve into 2 separate curves using a point that i've used for the division?
Thanks…

another comma separated txt file. I know how to import points (function Import coordinates), but I dont know how to connect them by lines if the only information I have about lines is the list of point numbers which should be connected. The txt file with point coordinates looks like:
-18,-36,-1000-18,-34,-19.728-18,-32,-17.603-18,-30,-15.372-18,-28,-13.121
...
And the txt file with line connections looks like:
1,22,33,44,55,6
...
Which means that I want to connect point 1 with point 2, point 2 with point 3 etc...
Both txt files are attached, thank you for the answer...…
