Project Description:
light seeking machines are programmed to push grounded bricks towards light cast onto the floor. (eg. the sunlight coming through a window). As the sun rises and sets the light path moves and the bricks follow, thus creating emergent patterns.
Lighting simluations via Ecotect will be used to:
1. Study how brick placement can change the daylight factor
2. Speculate and map the potential “buildable” area
3. Help calibrate the sensitivity of the machine’s light sensors (eg. only drive towards x range in lumens)
Daylight Factor – Analysis Grid:
This study shows how will the number of bricks, it’s placement and material effect the daylight factor of a space?
Using Tedngai’s “Ecotect Analysis Grid 2 Rhino” script, DF analysis data was converted to a surface as a means of 3D mapping “buildable“ area. The surface peaks and valleys represent high and low lumen levels, and or the absence or prsence of a brick.

Once in Rhino, the infomation was altered via the mesh patch command in order to make a more legible surface
Results from Data:
Further Alterations:
The data currently shows the presence of bricks as valleys and the absence of bricks as peaks. Further alterations to the script itself or to the surface in Rhino in order to reverse the values. By doing so, this information can simulate what the brick composition may look like.
