Run Radiation Analysis #2 now loads the NY sun data and JSON data from external files. All the rest of the code is commented out.

I suggest that Mostapha have a go at using this data to run an analysis and generated vertices and faces.

After that, I can have a go at trying to display the data with Three.js.

Coming up: Hot Spot #3 should display the selected building, centered in the screen, along with some of the adjacent buildings. Also you should be able to select any of the five NY boroughs.

#2 is really interesting. I need to check the code and see if I can get it to work. That was a key issue. Thanks.

I think that creating the geometry for Three.js would be a lot of work.

Wouldn't it be easier if you just create an array of color numbers?

This could be for an X and Y array of vertices or for a single linear array
of colors, say, starting from the top and working down the vertices from
left to right.

Which would be easier for you?

Each face - based on the original polyline segments - would have its own
array of colors.

If we take each floor to be 8 feet high, we could divide the horizontal
distance by 8 and then round the result for the X axis.

I can fairly easily take such an array of color numbers and create
identically section planes for each face in Three.js.

And the roof? How about we ignore the roof for Release 1 and just make it
the average color of the topmost side face vertices or some such thing?

Does this sound OK?

And approximately how many different color numbers will there be? And is
there some standard palette?

Hi Theo,

I think I still want to create the geometry. Matching the numbers with the grids won't be that easy if I give you a list of numbers.

I think roofs are really important as many people may look to the values to see the potential of installing PV's (and we can provide them the hourly profile next to the annual! Yay.). Because of the direction of the roof the radiation values on are drastically different from the walls.

Is it possible that you generate the planes first and give me the planes with the test points (mesh vertices in this case)? Then I can use that points to run the analysis and give you a list of colors back. In that case we will be sure that the colors match the order of the vertices. All I need is the list of the points and a normal that shows the direction of the base plane for each point. This will also solve the problem for the roof.

There are slightly different color pallets that I know. Here are some examples. We can try a new one for this project.

I will have sample planes for every wall face for you in a few hours.

More later...

Nice graphics. It's good to know what we have to surpass...

OK to close this one?

I must say I like pretty graphics.

Maybe wait until Alan says he's seen it. ;-)
