Shadow analysis en Puerta de Arganda, Madrid.

2013/04/03

Hoy publico en español puesto que los datos son en español y yo soy español:-) but if you guys have any doubt dont hesitate to ask… even if you have to use your french i will be around to answer you back… quand même !!!.

La idea era hacer un estudio de sombras de para mi propio uso pero extrapolable al uso para inmoliliarias. El modelado es como siempre usando sketchup y el plugin gracias a Tomasz Janiak:

Como ejemplo elegí mi propia casa en una urbanización al sur este de Madrid, en Vicálvaro concretamente. Como veis, cuanto más mire al sur más posibilidades hay de que de el sol y por la misma regla de tres, una exposición norte conlleva menos horas de insolación (lo que no quiere decir que no haya sol, claro… y menos en Madrid). Aquí la urbanización a estudio.

La propia configuración de la urbanización va a permitir que sea más o menos complicado que entre el sol por tu ventana, lo que quiero decir es que no es lo mismo una casa cuadrada independiente de dos pisos que una concatenación de bloques puesto que entre ellos también van a generar sombra, incluso obviamente hay que contar sobre todo en medio de la ciudad con edificios cercanos que puedan proyecta sombra sobre el nuestro y por supuesto otros artefactos tipo antenas o postes así como árboles. En este caso concreto esto no se ha tenido en cuenta para simplificar el análisis.

Por otro lado estudiamos el número de horas que da la sombra con cierta orientación (aproximadamente 245º)

Y otra con aproximadamente 46º…

También incorporo el uso de plugin Solar Analysis de Mr Capeluto que se ha tratado en un post anterior, lo que ayudará a tener una idea más clara de por dónde va el sol… como veis el norte está indicado y muestra cómo sale por el Este y se pone por el Oeste… este es un tema interesante a comprender bien, echad un vistazo a esta web de Microsiervos, por cierto interesante siempre:

2010/09/14

Good news!!!! They’ve probably released this Geovisualization Engine long time ago (It used to be an ‘in-house’ software) but I have just realized. I worked with this state-of-the-art TerrainView 3D software for six months while I was working as a GIS Specialist in Cape Town (South Africa)… What does this software has that no one of other softwares I know have????. Rain, snow, clouds, wind… Athmosferic conditions!!!!  A very reliable package… I have just uploaded a video rendered directly from a pre-recorded flight path… I will try to make my own while I work with this personal license key they have provided me for one month… Here it is!!. Hope you like it mates!.

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!
