onstrates the following:
1. The definition's functionality employing HumanUI for the custom user interface.
2. The evaluation of the definition's ability to handle different point cloud data sets.
3. Video reports with the definition's results, depicting the image acquisition path.
The process is displayed in real time, with minor speed up in some parts. The setup is responsive and benchmarks show that change between dense point cloud data sets is pretty quick (13-15M points, 40-250 images), with updates being calculated in impressive timings.
I would like to thank Heumann A. and Zwierzycki M. who provided direct support with HumanUI and Volvox. Also Grasshopper3d forum users Maher S. and Segeren P., who contributed with Rhino viewport manipulation scripts.

New in this Release:--------------------
PT-Rhino:
1- All 2D and 3D Paneling commands, now pay attention to the attributes of the source module. Morphed geometry is no longer added to a new layer and is placed in the same layer as that of the source module(s).2- ptPanel3DCustomVariable with mean option: added support to use multiple start/end modules.3- ptPanel3DCustomVariable command with mean option: added support to use points as part of pattern.
4- Fixed history bugs to custom2d and custom3d variable commands.5- ptOffsetBorder: added bitmap and draft angle options.6- Added history support to ptGridSurface* commands.7- ptPlanarLips command is discontinued and is now replaced with the new ptTabs. The new command has "Distance" and "Recess" options to create tabs with a miter. It works with planar surfaces and polysurfaces.8- ptUnrollFaces: Many improvements and new options.9- Many other minor bug and crash fixes.PT-GH:1- Added anew component to morph variable 3D components using mean or tween method between matching curves, meshes or surfaces.2- Added the new ptOffsetGrid component of a grid.3- Updated the ptMorph2dVariable component to accept a tree structure.4- Fixed a few miscellaneous UI bugs and crashes.Feedback:As always, feedback is ve
ry much appreciated.

e making on the surface in each direction. There are several ways you can go about this, but I think the easiest would be to either create the UV points for the isocurves manually or extract the points you want from the UV list..
As to surface coordinates versus world coordinates. The Isocurve component wants to be fed coordinates that represent 2D space. For example, if I had 2 surfaces that both had U and V domains of 0 to 1 and I fed a UV value of 0.5,0.5 to both, it doesn't matter how different those two surfaces are, because I'm expressing that point in relation to the 2D parameterization of the surface itself. Evaluating the surface at that 2D point then leads to a 3d coordinate expressed in world space.
Surfaces do have a third dimension, which is commonly refered to as W. The axis/direction of this third dimension is the normal of the surface at that point. So "technically" supplying a third coordinate value should also represent the point moving along that normal. In practice however, this is only really supported on operations that actually deal with normals on some level or another. So evaluating the surface wouldn't be one, but doing something like displacement would be something that might be interested in that third W value.
In GH, there is no 2 coordinate point because there's just no need for it. It would just be some extra components that would clutter up the space and do pretty much nothing beyond what could already be achieved with a 3 coordinate point.…

e looking to morph between?
At the end of the day, nearly all such operations come down to moving a bunch of points, and rebuilding your geometry from them. So the logical steps are:
1. Breakdown source & target geometries into points.
2. Calculate vectors from source points to target points.
3. Step2 implies that there needs to be an equal number of source and target points, which is by far one the most important considerations to make. If your are dealing with Nurbs, you must rebuild your geometries in order to have the same number of points, and if its meshes, you need to add tessellation.
4. Once you have the vectors, incrementally move points long these vectors in X number of steps, and each time you move them, rebuild your geometry from them using the same logic/sequence that you used to break it down in step1.
I posted a small example for mesh blending here. See if that helps.
If you are dealing with a Nurbs sphere and Nurbs Box, then things aren't very straight forward. For starters, a sphere is a single surface, while a box is 6. Since you can't make a box with a single surface, you will have to make your sphere with 6, somewhat broken down in the manner as if a cube were radially projected onto it. And then you will have to morph each of the surfaces to go from the 'part-sphere' to a flat face of the box by moving around their CVs.…
igher degree than 1 might have the same shape as a line, but it won't have the same parameter distribution.
In fact, look at a sine curve:
The red crosses are spaced along equal x intervals. These represent the parameters. As you can see the actual distance between any two subsequent crosses is not constant, even though their parameter distance (distance along x-axis) is.
Nurbs curves suffer from the exact same problem, it's just that they are proper 3D curves which are defined by 3 separate equations for all three world axis directions.
If I ask you what the coordinate is for this curve at x = 2.3, it's very easy to compute:
{2.3, sin(2.3), 0}
If I ask you what the coordinate is for this curve at 2.3 units along its length, you'd probably be stuck.

h other etc etc). Then randomly do the yellow lines (in X or in XY or in XYZ). Do not bother if the segments have equal lengths. Get the pairs of points (at end/start). Compute the big box (white).
2. With "help" boxes off this is the situation:
3. Do a Voronoi using the pair of points as above and the big box:
See that "equal" length lines means nothing with regard the "random" appearance of the cells.
If the deployment of the boxes (as in 1) is "flat" (meaning: no stacks in Z) then we have just a juicy Voronoi rectangular pepperoni pizza.

ts (that should make whole structure rigid body, right?).
Questions
1
In KarambaManual there is component called "BeamJoint" but i dont have it is it available only in pro version?
2
Is there other method form makeing my structure rigid body?
3
Should all lines be flatter before going to "LineToBeam" component. Unfortunately my system crash when i try to do that
Best,

nts which are located on different surfaces of these boxes. Now I want to divide the points in such a way that I have all the points located on each different surface in a branch of a list.
So if I have a tree for the points with 10 branches (for 10 different situations) and 4 different surfaces the points can be located on. I would like to have one tree as a result where I have the following struture:
{Situation 1, Surface 1}
{Situation 1, Surface 2}
{Situation 1, Surface 3}
{Situation 1, Surface 4}
{Situation 2, Surface 1}
...
{Situation 10, Surface 4}
My goal is to make individual surfaces based on the point clusters on each surface.
For now I tried the Point in Curves function, but somehow I still get points on different surfaces even though I should just get them for one of the surfaces.
Kind regards,
Florian…
