And List

By MRoth

This node returns TRUE if all inputs are TRUE. In some cases where you have many booleans, it is easier to use this node instead of the default and-node.

Concave Hull

By DomC

This node gets points clockwise with a given minimum distance.
The node has an additional option in the info-palette. Follow Deadlock means, that the hull can follow back the same points that already was used as a hull point. Deadlock off means, that a point can't be uses twice as a hull point.

The Algorithm behind the node:
1. Check, which points are in range of the point most left (bounding box for speed optimization)
2. Check, which points are exactly in range of the distance value
3. Check which angle in cw direction is the smallest and connect to this point

I think there would be a speed optimization possible with normalized vectors etc. So i would call this a beta version of the node.

Computing the angles of the vectors takes a while if there are many points. in combination with the cluster node it takes about 17 seconds for 4200 points. Seven Minutes for 8800 points. So check number of clusters and numbers of points.

The Idea was, to have a workflow for vectorize an image. This is a complexe project. Maybe it is worth to check other algorhitms with existing python external modules. But so far it works quite nice.

Ncs2Rgb

By MRoth

This node converts an ncs color code to an rgb color.

The color value is only an approximation and varies from the real NCS color depending on the screen and printer.

Make Planar Nodes

By DomC

Often what is missing to make usable Elements of this geometry is the fact, that
faces need to be planar to make buildable elements. Also it need to be planar to make
extrudes and other solids out of it.

The Two nodes "get Planes" and "ProjectPoints" are a step in this direction.

This example do nearly the same the existing Surface Array already can do. Except it directly
gets geometry from a subdivision object.

Anyway this has to be seen as a first step trying to model hulls with planar AND closed shapes. Which looks like a very hard task.
