hnical University of Denmark, Israel Institute of Technology and Aarhus School of Architecture, TopOpt for Grasshopper provides a number of optimization methodologies that extends currently available methods based on the 99-line MATLAB code for basic mechanical topology optimization provided by prof. Ole Sigmund of DTU.
The current alpha-release features 2d topology optimization based on the interactive optimization app developed for iOS and Android; topology optimization of continuum structures with tension and compression prioritization; and dual material topology optimization for optimization of composite structures with materials of varying properties.
Interactive visualization, 3d-optimization and further methodological extensions will be included in coming updates…

basis).
2. Rhino does not have a proper object display capability (objects per layer per view basis and/or per "collections" per view).
3. TSplines does NOT have any on-the-fly coordinate system definition capability (making "edit" a pointless waste of time). A small example about what this means as regards view navigation matters: imagine "hoovering" along a myriad of 3d objects: if you choose/opt for it: the moment that you touch an element (that could define a vector): this instantly becomes the working plane Z axis (very common capability in top MCAD apps). Not the same as a SpaceNavigator controller mind (far from it).
If these 3 were available > rebuilding anything with TSplines could be a joy (and very fast: about 2 minutes for your mesh)

3. Take into account the quality of the available editors (like VS etc etc). That said the "build-in" GH editor is a bit of a crap (but it's OK for smallish/not complex coding).

Reasons why I don't want to change the Integer parameter:
1) what about Number, and String, and Boolean, and Point, and Vector, and Line... should they also display the value? Or is the integer parameter supposed to be different from all the others?
2) what if you have multiple values inside a parameter. Should it grow to display them all? Should it grow to display only the first ten? Should it automatically switch to Icon-display?
3) would value display be a fourth kind of display type (alongside Name, Icon and App-default)?

2. Even cooler would be to make some kind of presentation preview. (GH disappears, rhino goes to fullscreen mode with somehow integrated remote panel). I like to watch apps/scripts made with processing, where sliders are really minimalistic.
3. Presentation preview may be optionally locked with password.
I realize that GH isnt processing, but this would be nice addition.

onstrates the following:
1. The definition's functionality employing HumanUI for the custom user interface.
2. Color based segmentation in manual and auto modes.
3. The evaluation of the definition's ability to handle different point cloud data sets.
This definition performs color based segmentation in two modes.
A manual mode, that implements the Delta-E CIE 2000 color difference formula, for targeted feature detection. An auto mode, that employs a simple RGB Color Range algorithm for quicker preliminary results.
RGB to XYZ to CIELab conversion and Delta-E scripts were based on Colormine's project code from github. Results have been compared and verified with the results of http://colormine.org/color-converter and http://colormine.org/delta-e-calculator/Cie2000.
Each stored class is charted and can be accessed through the UI, as shown at 2:30, where Delta-E CIE 2000, in CieLab color space, output results were found to be in perceptive conformity with human eyes, far superior to the preliminary RGB implementation.
Initial definition versions could process highly subsampled clouds in acceptable timings. Further research showed that employing the multithread processing of Volvox components, bundling the Delta E formula with the RGB to CIE lab color conversion script, per color segmentation calculations for a one million points point cloud would go down from 23 (c# script component) and 8 (vb script component) seconds to approx. 1 second (volvox script cloud component), thus allowing the segmentation of less subsampled point clouds.
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.

some weird engine, you know, he he) IS NOT like designing plain vanilla AEC things.
Therefore features/calculation methods/capabilities as found in MCAD apps (considered off topic by many in our trade) are mandatory for certain types of designs.
Anyway and if we forget FEA stuff, currently I have 3 C# goals:
(1) master the art of controlling the placement of existed blocks in GH defined topology(done),
(2) master the art of baking blocks(done) and
(3) master the art of baking heavily nested blocks that NX/Catia can understand (progress is slow).

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.
