ARCH 653 Project 2
Overview
In project
1, I created parametric mass and facade of One World Trade Center (1WTC) by
Revit. Now, the objective for project 2 is to improve the building model with a
visual programming tool, Dynamo.
Procedures
There are
two parts in the project to make the facade colorful with dynamo. The first
part reads the color from an image and assign the color to the curtain panels.
The second part changes the color by sun path. Figure 1 shows the original
facade of the building.

Figure 2
presents the dynamo program of the first part. At first, we have to select all
the rectangular curtain panels by selecting one of them and using the
Element.AllInstances node. Then we need to read the color from an image in figure
3. As there are 400 panels selected, we can set xSamples and ySamples as 20 so
that there are 400 pixels chosen from the image which can be used to assign to
the panels. In order to make the inputs format consistent of the
Element.OverrideColorInView, we should use the Flatten node to remove the tree
structure of the data. After running the dynamo grogram, we can see the façade
become colorful in figure 4.

program
Figure 5
and 6 show the dynamo program in the second part. In the first place, I select
all the triangular curtain panels and create normal of outermost surface of each
panel. Further, I set the sun settings, and the location is at New York. Then
we have to use the Vector.Dot to calculate the angle between the panel surface
and the sun direction. As the input value of the color range is between 0 and
1, so I have to remap the calculating results of the vectors angle. After I run
the dynamo program, the triangular panels will change color from red to blue
according to the sun path. We can see the color change from figure 7 to figure
9. At 8 am, the facade in the second part is totally red. However, the right
surface becomes purple at 11 am and the same surface becomes blue at 2 pm. We
can see that the surface facing the sun is red and the surface back to the sun become
purple to blue.
