"Hi Luc, maybe you really are running out of memory. Can you check in the task manager how many Megabytes Rhino is consuming? Do you have access to Rhino5 64-bit? If yes, can you test again, see if it fares any better? -- David…"

"I'm no longer getting the "Grasshopper display error," but now some components are giving me the following error: Error: Exception of type 'System.OutOfMemoryException' was thrown.   "

Luc Wilson replied to Luc Wilson's discussion Grasshopper Display Error
"It turns out that it is a rotate component that is causing the error. I get the error when rotate is creating 6,317,325 lines. I reduced the number of lines to 1,546,125 and the definition works just fine, calculating the solution in only 2 seconds."

DIVA for Rhino

DIVA-for-Rhino is a plugin which runs thermal, daylight, solar radiation, and glare simulations. Our goal is to bring validated environmental simulations directly to the conceptual design environments of Rhino and Grasshopper.See More

Andrew Heumann replied to Luc Wilson's discussion How to divide a surface into sub-surfaces with one vertex in each quadrant?
"Hi Luc -  It seems to me that there may not be a valid solution for every pair of curves. This definition works by assuming that two vertices are fixed (the end points of the curves, or the of the new division line from the previous step) and…"

"Andrew,What you describe is exactly the logic I was trying to set up. Thank you! It works sometimes on the definition you uploaded, but when I insert new curves it always fails. I am not sure if it is the definition or my inexperience with hoop…"

Andrew Heumann replied to Luc Wilson's discussion How to divide a surface into sub-surfaces with one vertex in each quadrant?
"Hmm... this is a challenging problem. The area centroid is dependent on the position of the vertices and the vertices are dependent on the area centroid, so the problem is a bit circular to solve. Also, I'm not sure it's always solvable,…"

Luc Wilson replied to Luc Wilson's discussion How to divide a surface into sub-surfaces with one vertex in each quadrant?
"The divisions between the surfaces don’t need to be vertical. In my first attempt at solving this I generated lines in grasshopper (in this case parallel and vertical) that I then used to split the surface. (I was thinking that I could vary…"

Andrew Heumann replied to Luc Wilson's discussion How to divide a surface into sub-surfaces with one vertex in each quadrant?
"In your drawing, the divisions between the surfaces are all vertical. Is this always the case? This is not the typical condition for a loft.  Also, what exactly is the center? The area center? The average of the corner vertices?"

How to divide a surface into sub-surfaces with one vertex in each quadrant?

How can you divide a surface (typically generated from lofting two lines) into the minimum number of sub-surfaces such that one vertex of the sub-surfaces is in each of the four quadrants (X,Y : X,-Y : -X,-Y : -Y,X) determined relative to the center point of the sub-surfaces and oriented to the global xy plane?In the below image Surface 1 fails because it has two vertexes in -X,Y and none in -X,-Y. Surface 2 meets the requirement of having one vertex in each quadrant, but is not the largest…See More
