Just my first thoughts. That breakdown in optimization is just an example. Maybe 'sections' is an old-school way of seeing things, I just wanted to share some thoughts on the kind of content I look forward to seeing. It can be pragmatic topics, but also theoretical, and allow folks to share their projects and research. Some categories are specific, others broad. I suppose I'm interested in community building with regards to computational design. I think SmartGeometry attempted to accomplish this at some point in the past, to some degree. However their focus appears to be in the workshops and challenges.
I recall the silly flame wars that the CG industry had 20 years ago (lame). I'd avoid that, even if it meant forbidding the mention of any specific software in certain areas or in the entire forum. Which would be tricky, but the endless flame wars and silly comparisons were such a waste of everyone's time in CG.
Without dwelling on this too much yet, I think that the software specific questions belong in software specific forums. If we already had a common language for computational design, you'd just need to add the right description as a meta-tag to any Dynamo or Grasshopper forum post, and you'd be able to find analogous solutions in either forum effortlessly, right?
The Dynamo and Grasshopper forums lack design-centric content. The emphasis is generally on the tools and workflow. Computational design is hybrid in essence, it involves both design and computer programming (be it visual or textual). We could really use a forum for knowledge exchange where the expectation is that both are discussed with equal status.
I disagree that such a forum ought to exclude professional programmers. It should include professional programmers whom have an interest in design, and also include professional designers whom have an interest in computer programming, and everyone in between, and enthusiasts, and artists whom are curious about algorithms as a creative medium, and academics, and students, and etc etc. As long as there is rich content and activity on design as well, not only the computational bit, then the crowd will be diverse and we'll all have more to learn from one another.…
d. If what you say is correct about the small difference between the global horizontal and direct/diffuse calculations in the MENEX model, than the discrepancy likely has more to do with the difference between the approximation of human geometry in the MENEX model (plane or cylinder) and the human geometry approximation in the SolarCal model (some coefficients derived from radiation studies of mannequins). I noticed some fairly large differences between using a suggested global horizontal method and a direct/diffuse method with the SolarCal model (differences on the order of 20%) but I imagine that this is because a mannequin human geometry is more sensitive to changes in solar orientation than a cylinder or plane. All of this is very good to know.
Yes, I guess this might be the case: the sensitivity of the SolarCal model to different parts of human body surfaces and surfaces areas.
Am I correct in understanding that you recently corrected the grey-body assumption about sky temperature in the Thermal Comfort Indices component with this commit? https://github.com/mostaphaRoudsari/ladybug/commit/a2a37b6dccc4e750...
The previous incoming long-wave radiation was derived by Ångström for clear sky conditions. The added correction "(1 + 0.22*((N/10)**2.75))" is a fractional cloudiness factor by Maykut and Church (I attached the publication below which mentions it).
So the emissivity coefficient of the (cloudy) sky is now:
epsilon_sky = (0.82 - 0.25*(10**(-0.094*0.75*e))) * (1 + 0.22*((N/10)**2.75))
I do not think that you could use the same value to calculate the sky temperature with Stefan-Boltzmann law, as the incoming long-wave radiation has been derived from the air temperature (2 meters above the ground), not the sky temperature. So by:
skyTemp = (La / [epsilon_sky * sigma])^0.25 - 273.15
One would get the air temperature from which La is derived, not skyTemp.The possible reason why SolCal Mean radiant temperature is currently getting similar values to Thermal Comfort Indices Mean radiant temperature could be that fact your epsilon_sky is almost equal to 1 (0.95), so it depends solely on La.I spoke with Dr. Blazejczyk, and got a publication on different sky temperature models. Apart from upper mentioned Swinbank, Berdahl-Martin, Melchor it has a lot more methods with mutual comparison of their resulting values. I attached it below.…
d react in length to the variation of their respective angle deviation from the sun.
For the moment I have established a way that depending on Bigger than/Smaller than X value, there is a dispatch of data to produce to types of panel lenghts. As you can see on the image.
But I would be interested to find the way to organize the list of all angles and classify them in groups like 5 packages of 20 degrees deviation. So, the panels deviated 16,3 and 27,9 degrees would go in the package of 15-35º, for example, and the 33,1 would go in the 35-45º...etc..
And the question would be to assign the different groups of angles, to given positions for the vectors that define the panel surfaces.
I am confused at how I should tackle this problem. Is it a question of dividing domains? Or creating sublists? But then, how can I assign the data to a set of positions? Dispatch only works with A/B..
And if so, how could I limit the positions of the vectors that define the surfaces, to a min and max length that would not overlap out of the base pattern?
These are huge questions, eh? But I'm sure that someone has tackled this problem before...
Looks like an accumulation of pretty standard problems,..but all together!
Thanks a million for any examples or hints on how this could work!

eps are represented by multiple surfaces so the discussed techniques are not fully workable.
the attached files include my test gh and a solid file to input. I have been able to map a suitable voronoi latticework onto the brep surface - but then I'm stuck. I cannot offset the curves on the brep and create a useable strut surface that way. I cannot intersect swept pipes with the brep surface to create surface patches that could then be joined.
I need some elegant ideas; I seem to be going down a rabbit hole at the moment where I am doing ever more complex workarounds for the grasshopper capabilities. (A case in point; the rail sweep is not working for me for closed 3D polylines, so I am having to cut them up and sweep and cap the segments. Ugh).
Example input brep
Curves on brep - but no simple offset / trim mechanism
Potential rail defining strut trim - but no way to do so...
Brep / rail intersect - but no way to turn this into a surface...

r-workshop programme will focus on the design and 1:1 fabrication of an interactive pavilion for the 2012 International Festival of Electronic Language (FILE). Located on Avenida Paulista, the pavilion will react to light sensors and human activity, so as to transform and create a range of different lighting and spatial effects, triggering further movement and producing an interactive feedback loop of behaviour and response. To accommodate this responsiveness, the design should be developed using recursive scripting, associative modelling and digital fabrication.
Each workshop will focus on a different phase of the pavilion’s design and construction. Instruction will be led by Rob Stuart-Smith of Kokuggia and Tristan Simmonds of Simmonds Studio, with Lawrence Friesen of Generative Geometry, Anne Save de Beaurecueil and Franklin Lee of SUBdV, together withand other AA tutors, as well as local structural engineers and set-designers. Each workshop will offer introductory instruction in computational design - Grasshopper, (GECO, Firefly) and Arduino, and digital fabrication, while advanced instruction will be offered to participants undertaking multiple workshops.
Workshop 1 will develop design variations in small models, as well as material and structural scale modeling, testing and initial 1:1 prototyping, following computational and digital fabrication instruction. Workshop 2 will produce 1:1 prototyping. Following computational and digital fabrication instruction, it will explore the mechanics and electronics of the light-sensors and motors that generate the transformations of the pavilion. Workshop 3 will fabricate the final elements, working directly with manufacturers, testing partial assemblies. Advanced development of all circuits and Arduino scripts will take place following computational and digital fabrication instruction. Workshop 4 will focus on the final assemblage of the pavilion on site.

I would to convert then to meshes: when I connect the triangular surfaces to mesh, they are divided into two smaller triangles.
I would like the triangle AEa, instead there is an other segment that connects point E with the midpoint of Aa!
Any ideas?
Can you help me, please? Thanks in advance
