shadow animation

Using either DIVA or Geco with Ecotect, it is easily possible to animate shadow volumes during the course of any day of the year.

energy simulations

Conducting energy simulation within the grasshopper environment makes an iterative work flow much more simple.  The example below, using the DIVA plug-in, shows illumination values (represented by a gradation from red to blue) under the red canopy.  Note the data tags.  These values are available to shape surface strategies.

The example below uses the Geco plug-in to integrate with  Ecotect.  Here the total incident solar radiation is represented as a topography from red (hot) to blue (cool). The definition requires a .wea file.
