Solar + Shadows analysis on Rue Massillon, Nantes (France)

2013/04/04

This is the beautiful building in from of my house in Nantes… Let’s model it first using Sketchup. Also i have used a non standard style only for visualization purposes…

If we have the North behind us this means we are going to have a lot of light… but so far we are just guessing…

Now we know if for sure. Take a look at the results by M. Capeluto’s Solar Analysis.

If we face South we notice there’s a lot of sun in the other side of the building (every line is a summarized path during a month, being the higher the closer to the summer solstice)

Please take a look at the video prepared by Tomasz Janiak, the developer of the tool.

Hope you guys find it interesting. Please let me know your thoughts.

Ever tried Google Earth 3D Building Maker?

2010/02/18

I started modelling 3D buildings quite a few years ago, I used to use 3D StudioMAX… After almost forgetting everything i knew about modelling, 3D and so on Sketch up was released by Google. In a few days i was not just making demos but working and producing!!! Its extremly easy!!!!. Now They have just released something called “Google Earth 3D Building Maker” and its amazing, theres no need to know anything about modelling, you just have to insert polygons and move vertexes…very intuitive indeed!.

place the number of polygons you need…move their vertexes to the proper position.

Directly upload it to your Google 3D warehouse…

And finally take a look at it inside Google Earth… that’s it!.

You can always use Sketchup to perfect it… but it’s good enough…a piece of cake!

Some of the buildings located in Madrid and Cape Town are mine!
