Stage 2 “Ponyo” — Modeling Approach

A sine wave was used to shape a wall, based on user-input parameters as described below. Panels are re-sized according to project instructions (4” tall x 8” wide) by converting the input height of the wall (provided in feet) to inches, after which the appropriate conversion is done to convert panel sizes to 4”x8”. After the sine wave was extruded, 4-point panels were placed across the extruded surface. Special attention was placed in assigning the correct ‘u’ and ‘v’ values to the Quad Panel function and the ‘xSamples’ and ‘ySamples’ inputs to the Image Pixels function. The number of panels in the vertical direction must map to the ‘u’ and ‘ySamples’ inputs, and the number of panels in the horizontal direction must map to the ‘v’ and ‘xSamples’ inputs for the image to properly be read and displayed.

To ensure that the image pixels are read and displayed in the correct orientation, the list of image pixel colors was fist reversed, then flattened by one level. To adjust the panel heights based on brightness, the image brightness values were mapped to new minimum and maximum values, defined by 4” to 36”, or 0.333’ to 3’. From some trial and error, I realized that the panel heights were extruded from the back surface, rather than on the front side. By negating the range minimum and maximum, the extrusions were able to project from the front surface, rather than the back.

Stage 2 — Adjustable Parameters in the Design

• Image input from file path
• Wall length
• Sine wave position, amplitude, and number of waves
• Wall height
• Adaptive component family type for panels
• Height of panels, given the image brightness

Stage 1 “Beach Landscape” — Modeling Approach

The arc design represented below for Stage 1 depicts a beach landscape onto a curved wall, though using a typical right-side-up image as input results in a projected images that is rotated counter-clockwise by 90 degrees. The final image depicted below was yielded by providing a pre-processed image that rotates the original image by 90 degrees clockwise, which then enables a right-side-up image as output. Alternative ways to create an arc shape in Dynamo may have yielded more favorable results that may otherwise have not required this pre-processing step.

There is logic encoded to ensure that all panels are square-shaped. Other decision-making for the modeling process are aligned with that of Stage 2. Since reversing, then flattening the image like Stage 2 resulted in an upside-down image, the approach instead was to flatten, reverse, then transpose the image pixels to result in a right-side up image.

• Arc origin point
• Wall length
• Arc radius and start/end angles
• Wall height
