hi

this is actually a manifold question that has to do with my lack of understanding of 3d scenes in processing. I have a network graph that is actually 2d but in order to pan, zoom and do other 'camera' functions I needed to move into 3d space.

Now that I am in 3d space and I have all my nice camera operations sort of going I have lost the nice interactions I had with the graph in question IE clicking on nodes in the graph previously highlighted them, you could drag them etc etc. Now none of that is possible. My hunch says that the part of the code that checks whether the mouse is "on" the node needs to be tweaked because presumably what I am seeing is only some sort of representation...but the bottom line is , I have no idea how to sort this out.

Related, I believe, to this issue, is my desire and inability to draw a nice gui 2d overlay despite following simple instructions in other threads...anyways, i guess one thing at a time.

To make matters worse, I can't export due to some processing bug which apparently is fixed for the next release...

thanks for your help, in advance.

ok. trying to get your hack going. I understand it in principle but some of the minor details are tripping me up

I've commented out what I have tried but you can see the sketch I'm trying to apply it to here

upsdn.ca/processing/GraphLayout_animals_rehash3D02/applet/

I had trouble with where I was swapping out the for loop through your 'boxes' for my nodes...something about
"The type of the expression must be an array type but it resolved to ArrayList"

as you can probably tell I get confused about how to manage collections and arrays. I typically try one thing and if that fails I move onto a different approach eg length vs size() for determining the number of items...

from what I can tell I have a series of Nodes placed into an ArrayList and I need to convert back to a Node array or Node[]...how would one do that?


any help you could provide would really be appreciated
