So:
1. We need some random collections (pts) on a List of untrimmed surfaces. Homogenous "random" distribution is better than the method used in the Dubai abstract sketch attached (but at some CPU cost, not a big deal since pts a few: David Rutten did some very good jobin the GH component on that "even" matter). Adding random "noise" (with user controllable min/max values) is the easy thing: like the 256 does.
2. We need some "similarly" defined random pts applied on each surface edge.
3, We "join" 1+2 and do the del mash thing (that's the easy part). Thus the "similar" constrain is critical here for aesthetic purposes (see 2).
4. For each subsequent surface (sharing common edge, that is) we repeat by adding the pts related with the common edge.
5. Arriving to the last surface: we use either one common edge or two if the surfaces define some "closed" (in U or V) combo.
PS: Novice means nothing: we all are novices more or less: so don't let this "truncate" your aspirations.…
o or more curves, I would like it to affect the entire structure, as shown in figure 2.
Figure 3 shows a model of what I am attempting to achieve in two dimensions.
I have attached my grasshopper file with the grid shown in the images and my inital attempts at trying to undertstand and achieve this result.
Any help would be much appreciated,
Thanks,
Alex

…
are just the 8 cases, so you're actually doing it right here (scroll down on this page, and you'll see a separate subset all about marching tetrahedrons http://paulbourke.net/geometry/polygonise/). The benefit to using marching tetrahedrons is exactly this: that the number of possible "cuts" through the tetrahedron are dramatically smaller in number than those through a cube.
However, I have found that also what you're seeing that the linear interpolation creates some odd distortions (which is why I went ahead and later did the marching cubes implementation). Some of this comes from the density of the sampling grid: the more dense, the fewer distortions.
What I would suggest, if you want a (relatively) quick way to improve this outcome:
1) build up a full mesh rather that bunch of surfaces, and use Rhinocommon to combine identical vertices, and rebuild the vertex normals
2) run a couple rounds of laplacian smoothing on the mesh to better distribute your vertices (for each vertex, make it equal in location to the average of its neighbours)
3) create a line normal to each vertex roughly the length of your sampling grid and test the endpoints of it against your scalar field formula, and then do one final linear interpolation between those two points for your vertex.
This should give you a smoother mesh for sure.
But good work getting this far! …

thisthe errorthat appen when i lunch E+ with only one zone....what is going on???? …
radiance parameters to get rid of blotching. To add another level of complexity to my problem, I am running simulations with a translucent material with the following properties: void trans testTrans
0
0
7 0.478 0.478 0.478 0.000 0.010 0.178 0.635
I have had no issues with the renderings when I use clear glazing, as seen on this image:
However the blotching-issue becomes very noticeable when I introduce translucent glazing into the scene:
For the two above cases I used the following parameters:
_av_ is set to 0
xScale is set to 2
_ab_ is set to 6
_dc_ is set to 0.5
_aa_ is set to 0.2
_ad_ is set to 2048
_st_ is set to 0.5
yScale is set to 2
_ps_ is set to 4
_ar_ is set to 64
_as_ is set to 2048
_ds_ is set to 0.25
_pt_ is set to 0.1
_dr_ is set to 1
_pj_ is set to 0.9
_dp_ is set to 256
_dt_ is set to 0.25
_lr_ is set to 6
_dj_ is set to 0.5
_lw_ is set to 0.01
I ran another test with increased Radiance parameters and got the following output:
with the following parameters:
_av_ is set to 0
xScale is set to 6
_ab_ is set to 6
_dc_ is set to 0.75
_aa_ is set to 0.1
_ad_ is set to 4096
_st_ is set to 0.15
yScale is set to 6
_ps_ is set to 2
_ar_ is set to 128
_as_ is set to 4096
_ds_ is set to 0.05
_pt_ is set to 0.05
_dr_ is set to 3
_pj_ is set to 0.9
_dp_ is set to 512
_dt_ is set to 0.15
_lr_ is set to 8
_dj_ is set to 0.7
_lw_ is set to 0.005
Although the second blotching case is much better than the first, it is still very bad for hours when the sun is lower in the sky. The above images are rendered for a clear sky at 18:00 in Germany in a West-facing room.
Sorry for the long post! Can someone help? Kind regards, Örn

nts that I have found helpful and will be included in the next release, but you can try them now. They are online at https://github.com/fequalsf/Crystallon/tree/0972066e468f0a7a592ff4e7e88226028dcb029c/V2.1I have been interested in finding ways to save settings for different iterations of a design which can be baked into a rhino file and used again later. These tools I've made are for working with divisions of a surface.The first tool (Divide Surface) is for dividing a single surface using UV parameters and outputting a quad mesh. Simple enough. What makes this powerful is you can use that mesh with the "Morph Between Meshes" tool to create your voxels. So now you can morph between surfaces with the same number of divisions but with different parameters. The other nice thing about meshes is they are simple to work with and can be further modified with other plugins (such as kangaroo). They can be baked, manually edited in rhino and saved as STL or OBJ files to use again later. I will be updating all the tools eventually to output meshes.
The next tools are for creating those divisions. Any of the components that require a parameter input need a range of values from 0-1. The simplest way to do this is with the "Range" component. The default domain is 0-1 so you only need to give it a number of steps.
To make the range non-linear, there's a few components you can use. Graph mapper is the most common tool, but you could also use the gradient tool.
But these can be difficult to work with and quite limiting. Graph mapper has a limited set of graph types to work with (I tend to use Bezier) and the gradient tool makes a steep curve which cannot change. Also making small changes is difficult and saving a setting for later is not easy.
So the next tool I made is a curve plotter. This takes your range of number (X values) and your remapped numbers (Y values) and plots the points to either a polyline or interpolated curve. This way you can see the curve the gradient is making or bake out a graph mapper curve you want to use later.
The next tool I made is a curve graph mapper, so you can map numbers using any curve drawn on the XY plane. This gives you much more freedom than the graph mapper and is easier to make small adjustments. Then you can always make many iterations of a curve and go back to any of them saved in the rhino file. There are options to view tags with the values on the curve as well as a gradient preview.
If you take a look at the curve created by the gradient tool, you can see it is basically creating a Bezier curve from the handles on the gradient (position is X value, color is Y value). The problem with using it for division parameters is the tangency of the points is always in the X direction creating a nearly horizontal section in the curve. This will give you a series of the same values, which we don't want. The falloff of the curve is also quite steep with no way of adjusting it.
If you make a lot of divisions you will also notice stepping in the curve. This is because the gradient uses RGB colors which is only a range of whole number from 0-255. So you only have a total of 256 values from 0-1.
Yet there is something elegant and user friendly about Bezier curves which makes them nice for creating gradients. So the last tool I made is for creating a Bezier curve from points. All you need to do is input at least 2 points. The second input is the tangent length multiplier (which can be one value for all or one per span of the curve) and the third is the tangent rotation in radians (also either one value or one per span).
The values are shown on the curve and can be baked as text tags if you want to save them and use the same points and values later. Or you can just bake out the curve. This makes for a simple smooth curve that makes a nice gradient.
