Triangulation

Is it marching cubes standing behind those meshes ?

http://vimeo.com/37022267 This is project by Matthijs la Roi

I just want to learn some more about types of recontructing mesh form points, but I cant find more than marching cubes, and scripts that overwhelm me :D

I know that there are some processing nerds here, please tell me some more about libraries used with processing. I am completely unfamiliar with processing, I just need topic too focus on it.

Thanks !

maybe a hint for you.

Good one, but there are so many questions to ask !

do you know what are pros and cons of processing ? is it possible to export geometry from processing as 3d geometry ? (i know its a lame question, and Iam quite certain that yes, but are there any limits ?)

and last one - why processing is so fast ? good libraries for complex geometries or low quality of geometry ?

sorry,

i can not help you, cause i'm not familiar with processing.
but as you've probably noticed, the guys from pandalab held the workshop in delft.
i am sure that they are able to answer your question. (:
So just contact them?

I believe there is no mesh standing behind those lines. It is just agent trails connected to their closest ones( up to six neighbours approximately). The most sufficient mesh producing library-system in processing is this by Karsten Schmidt. There might be some documentation on the algorithms he is using in his library. As for the agents, the look like Jose Sanchez's plethora agents, but I might be mistaking on this one.

I heard about toxiclibs here (lot of good words). As I said before, I know nothing about processing, so thanks to you , now I am quite sure that this is some direction for me, and I wont waste my time with learning something which is "not as good as something else" (if you know what I mean)

Edit : I looked now at http://toxiclibs.org/2011/12/metworks-workshop-facade/ . What Iam really interested in is step 5 :) (please, please dont let it be marching cubes again ;))

There is an embedded function into toxilibs, that creates meshes through point clouds with volumetric brushes and another one using isosurfaces. I don't know the source code behind this and i am not sure whether Karsten has made it public. I haven't focused at all at mesh creating algorithms (only naming them) so I cannot be much of an assistance to this cause.

In answer to your previous questions I enjoy grasshopper and processing for different reasons. you can export any type of geometry you like, if you code the export function that is. Processing is faster at simulations but time consuming in geometrical configurations(due to labour of coding everything).

I personally like to export data sets from Processing and manipulate them in other platforms.
