Walk in the Park - an image of the Dynamo geometry

To design this park, I wanted to have multiple divots with reasonably sized cuboid shapes for construction. Therefore, for the cuboid sizes, I split the 200’x200’ into a grid of 25x25 blocks which would make each block about 5’x5’. This gives some space for seating for small groups. I wanted there to be multiple levels in the park which is why I chose 3 waves, which allows 2 separate hill-like shapes in the park. I also set the attractor to the side as to not make the shape fully symmetrical, giving it a more interesting landscape.

Eliminate the Echo - an image of the Rhino geometry

For the design of the acoustic damper, I wanted to be able to show more of the ripple effect without the damper taking too much ceiling space. For this, I chose smaller cylinders throughout the damper to be able to show a larger number of waves. To make sure that the damper doesn’t take up too large of space, I kept the wave amplitude and base height to a minimum. I had the attractor closer to the corner of the damper grid to better show the effect of multiple waves, like taking a quarter of the ripple shape to give the object more dimension.

Happy Facade - an image of the Revit wall

For this facade, I wanted it to be a feature, so I decided to make the overall wall size 50’x35’, which would typically span about 2 stories. This can be a lobby feature given it’s unique window shapes. I chose to place the attractors nearly opposite corners, and use 2 waves to give the facade a zig-zag like pattern with the openings. This can give variation in the lighting throughout the day depending on the angle of the sun at a given time.
