In the article Lost in Parameter Space, the author describes the process of translating physical model into a digital form. One of the core terms and concept that frequently appear during the process is abstraction and reduction. The authors imply that abstraction is a process of reducing the amount of information by considering the general concept or the main characteristic as opposed to the concrete reality. Reduction on the other hand, is a process of restructuring or eliminating unnecessary parts without altering the contents. These two terms could be related back to the process I undertook in module 1 when generating the analytical drawings from the natural pattern. The analytical drawings I produced are a process of abstraction of the fern based on the 3 distinguishable characteristic namely movement, balance, and symmetry. The process of reduction was demonstrated when creating the recipe for the analytical drawing. Although the description could’ve easily been a couple paragraphs, I chose the optimum way of representing the process (a brief 50 words with the aid of pictures).

Digitisation of the model

Method 1. Generating contours by tracing profile curves First I tried the first method by tracing the overall shape of the entire model using the orthographic view. Although it was a fast and relatively simple process, the resultant form was becoming too abstract that it was losing the initial idea.

Method 2. Trace and loft reference curves I initially drew a multiple of circles to trace the contours of the base form. I then slightly . manipulated the angle and the length between each circles using the top view. Finally I selected all the circles and lofted them to arrive at a digitalized form. The form was futher developed through the manipulation of control points to give a more organic and smooth surface. Although this method was a little bit more time consuming, I was able to produce a more accurate representation of the clay model

Standard 2D&3D Paneling Here I used the standard 2D paneling option to explore the various effects that could be implemented in the lantern.

I felt the filtered lighting effect produced from the standard panel were too . predictable as they are directly filtered from the shape of the geometry. Therefore I created a random geometry (trapezoid) for the base which would filter the light once and again by the 3D structure which is based on the emerging form ( Symmetrical layout of leaves) Although the overall form created from rhino is aesthetically pleasing and symmetrical, the lighting effect was merely visible. It was also a tedious job even to create 4 connected panels because the tabs were too small.

Figure 1. 3D custom panel applied at 10 uv poiints As an imrpovement to the first 3D custom panel, I enlarged the geometry inside the 3D structure (circle) to produce effects that are clearly visible. I was pleased with the shadow produced from the prototype (figure 3). It was also easy to produce the prototype (joint panels) as opposed to the first custom panel .

This panel was extremely hard to produce because of how the 3d Structure is layed out. Although the shadow is wel lahyout, It would be a tedious and a time consuming job to produce this panel in a larger scale.
