doing this with the current tools or a bit of scripting since the Flickr API allows you to make requests in a REST format, but utilizing the Flickr.net API library makes it much simpler.
First and foremost, you need a Flickr API key...do you have one of those?
A great way to get to know the Flickr API is with the API Explorer. Here is a link to the page for the flickr.photos.search method explorer: http://www.flickr.com/services/api/explore/flickr.photos.search
The cool thing about this page is that it generates the REST Http call towards the bottom. So, here is what I did:
1. Grab the coordinates of the bounding box per Flickr API request:
bbox (Optional)
A comma-delimited list of 4 values defining the Bounding Box of the area that will be searched. The 4 values represent the bottom-left corner of the box and the top-right corner, minimum_longitude, minimum_latitude, maximum_longitude, maximum_latitude. Longitude has a range of -180 to 180 , latitude of -90 to 90. Defaults to -180, -90, 180, 90 if not specified. Unlike standard photo queries, geo (or bounding box) queries will only return 250 results per page. Geo queries require some sort of limiting agent in order to prevent the database from crying. This is basically like the check against "parameterless searches" for queries without a geo component. A tag, for instance, is considered a limiting agent as are user defined min_date_taken and min_date_upload parameters — If no limiting factor is passed we return only photos added in the last 12 hours (though we may extend the limit in the future).
So, I went to Google Earth, picked a city (London, UK) and dropped two pins:
This gave me two locations, which I can put into the Explorer Page next to the bbox option. Here is what I put for these two points: -0.155941,51.496768,-0.116783,51.511431
2. Check has_geo
3. In extras, type in geo
4. Make the call!
You will see a list of responses in an XML format, these responses will be from the first page. Geolocated photos are limited to 250 / page, so you will have to grab them page by page.
If you want to add more options (minimum upload date, maximum upload date, etc) you can do this as well)
The best is at the bottom, you get the full http call for this: http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=ffd44f601393a46e86aa3a5f8a013360&bbox=-0.155941%2C51.496768%2C-0.116783%2C51.511431&has_geo=&extras=geo&format=rest&api_sig=b42330e5d1523bd5fe60c2ad43acde99
Notice this call has some other api key, you should eventually replace this with your own.
You could copy and paste this into a browser and you will get the results with the latitude and longitude:
So this is really what you need to know to do this through GH. Since gHowl has an XML parser component that can access files on the web, you should be able to use the same http call into this component.
Eventually, we get a response, and we need to grab the lat and lon data. With gHowl we can map these to xyz coordinates, and generate the heatmap...this is just a linear mapping:
Attached are both the Rhino file and the Grasshopper file, as well as the image underlay.
I am working on a series of components that makes this more straightforward, but for now, this should get you started.

cy of design communication and the control of information-flow are as important as the creativity of ideas. In response to the concurrent digital evolution emerging in the architectural industry world-wide, the Faculty of Architecture at The University of Hong Kong will host a two week intensive summer program named Digital Practice.Led by professors from The University of Hong Kong, as well as invited practitioners with expertise in practice of cutting edge digital techniques, the program offers participants opportunities to experience applications of computational tools during different stages of an architectural project, i.e. concept design, form finding and optimization, delivery, management and communication of design information under the team-based working environment. By learning advanced computational techniques through case studies in the context of Hong Kong, participants are expected to go beyond the conventional perception of technology, considering users and tools as a feedback-based entity instead of a dichotomy. The program, which is taught in English, includes a series of evening lectures related delivered by teaching staff and invited local architects.對於高品質的建築專案,創意之外,專案過程中高效的設計資訊管理和交流成為項目設計深化和實施必不可少的環節。今天,數字化技術不但改變了建築師的繪圖工具,影響了設計的過程,而且提供了工程建造和管理實施的更有效、更高效的手段。針對建築的數位化演進,香港大學建築學院將於2011年暑假期間,在香港大學建築學院舉辦“數位化實踐”國際研習班。在香港大學建築學院教授及有著相關豐富經驗的外聘實踐建築師的指導下,學員將有機會體驗在專案的不同階段(如概念設計、設計形式的生成、優化,設計資訊的管理和交流),如何有效地應用各種運算智慧化技術(從設計的數位化生成和建築資訊類比到物理模型),提升設計實施的品質,增加設計團隊對於方案的控制。我們將挑戰對於“技術”的傳統認知,即相對於使用者它不僅是工具,更是與使用者互動的媒介,二者形成一個有機的合體。研習班期間會安排系列講座,展現數位化技術在實踐工程中的廣泛應用。…
f my list.I don't understand why, but I guess I must be too young user ^^In the original list, i have a path {0;0;0;4} with two index and after the random node, {0;0;0;4} has 88 index.Items are not correct?I would have a comparable structure has the right list on my jpg (photomontage...)How I can do that?Thank you in advance

robablemente las uniones son forzadas/rotadas levemente para que calcen.
Probablemente se puede variar el angulo de 90° entre cada pieza a un angulo que permita crear el octagono perfecto, pero habría dos posibilidades de giro entre cada pieza.
Tal vez el problema hay que repensarlo desde el octagono/poliedro que forman los triangulos en el modelo y luego generar los triangulos.
Bueno aca mi definicion y algunos comentarios:
- Hoopsnake pide una condicion inicial que solo la utiliza en la primera iteracion (input S).
- Luego hay que definir el algoritmo reiterativo/recursivo que es toda la parte de abajo. Como input se utiliza el output S de hoopsnake (en la primera iteracion es la misma informacion que ingresaste en S).
El resultado de este algoritmo/proceso vuelve a ingresar a hoopsnake en el input D para una nueva iteración.
- El output H es el historial de toda la geometria/datos procesados en las iteraciones.
Ahora te explico el algoritmo:
- Se toma el triangulo y se sacan los puntos en las esquinas.
- Se revisa si los puntos estan contenidos en otro triangulo existente y hago cull para dejar los libres (ocupo el output H del hoopsnake para ver los triangulos de las iteraciones anteriores). En la primera iteracion hago un bypass para dejar todos los puntos iniciales libres (ya que no hay historial en el hoopsnake).
- La parte de abajo es para elegir una de las dos opciones max disponibles (tu comentaste arriba que habia tres opciones... en realidad son tres opciones en la inicial, luego son solo dos opciones. No se que va a pasar si se se completa el octagono, teoricamente habría solo 1 opcion disponible, pero no pude reproducirlo por el problema geometrico).
A modo de ejemplo, en la imagen le deje todas las opciones disponibles y conecte directamente (dos para el triangulo) para tratar de generar los octagonos.
- La parte final es simple, desde el centro del triangulo se genera una linea hacia las opciones disponibles para generar un plano perpendicular para la simetria y luego se rota en 90° (que creo debería ser otro angulo). Puedes mover el slider del plano perpendicular para generar la interseccion deseada en los triangulos (0.5 para interseccion completa).
Como ya te indicaron, yo tampoco hice el tema de las areas.. pero deberia ser simple en mi definición: Calculas el area del output H (triangulos), aplicas flatten, mass addition y si el numero resultante es mayor al area de la placa que quieres, debería generar un valor falso que va en el input B de hoopsnake.
Sorry que no haya ocupado tu definicion, pero ocupe un grasshopper antiguo y ademas ya había solucionado un problema similar con un alumno el semestre pasado, asi que realicé lo que me acordaba :D
Saludos y suerte!

t, you can see 6 (+) signs with what you can add (A,B,C,P,Q,R).
Let's say you add A = 90 and B = 50.
Now you can't add the third angle (cause its 180-(50+90) = C output).
What you can add at the moment is P,Q,R.
You choose to add P = 10.
There is no more a possibility to add Q and R.
All component outputs now give us the data.
2. Triangle with P,Q,R
When you zoom the component, you can see 6 (+) signs with what you can add (A,B,C,P,Q,R).
Let's say you add P = 15, Q = 20.
Now if you add R, the component's outputs all the angles and edge lengths.
If R > P+Q then component throws warning. (> or >= ?)
You cannot add A,B or C anymone.
3.Triangle with P,Q and C
When you zoom the component, you can see 6 (+) signs with what you can add (A,B,C,P,Q,R).
Let's say you add P = 15, Q = 20.
Now if you add C (angle), the component's outputs all the angles and edge lengths.
You cannot add A,B or R anymone.
To make it all easier, disable the possibility to internalize the data.
Tolerance issue... Maybe round the angles always to floor , with 0.1 precision ?

ned' as this is kind of unknown to me, which is why I wanted to look for a tool or script that might generate some geometry between the two. The fundamental principle is that the input meshes must retain 90+% of their original geometry (ie not deformed into an approximated wrapped shape) but be joined together by some sort of mesh geometry which acts as a link between the two shapes. The form for this could be highly abstract and doesn't need to conform to any parameters other than allowing the original meshes to be highly visible. I hope that makes sense, it may only be clear in my mind now that I have pursued it this far!With regards to the geometry wrapper, I found the example file that you sent us and attempted to plug in similar variables with my meshes, however the values returned by the geometry wrapper are constantly zero, no matter what I seem to change. I am currently plugging the mesh into a bounding box, which forms the box for both the geometry wrapper and iso surface and then inputting integers for the remaining parameters, though I'm not quite sure what actions these are performing. Would it help if I could send you my definition? I'm currently trying to internalise my meshes, though my rhino keeps crashing when I try! If you aren't able to follow any of the above let me know and I'll try and put together some simple diagrams that may explain it better.
Thanks,
Tom…
