Daniel Brookman: Barbie Ormolu, Intro

My work in this class will examine the role of the Barbie doll as an icon of popular American culture, exploring unexpected themes the Barbie brand can represent. The project will take the form of a desk that will feature ormolu mounts derived from Barbie iconography and other relevant imagery.

Ormolu comes from the French or moulu and means “powdered gold.” The term denotes a gold-colored alloy of copper, zinc, and sometimes tin, which is cast and then gilded. Ormolu was predominantly used in eighteenth century furniture decoration and timepiece construction.

Examples of ormolu.

Sketches of desk and components.

These sketches illustrate the French-inspired desk and ormolu components that I intend to create. The center of the desk will feature an asymmetrical medallion in mid-relief (top left), while each front corner of the desk will be adorned with high-relief figural mounts (top right). Along the back of the desk, a jungle scene will be rendered in low-relief and will span the width of the piece.

After initial sketching was complete, I purchased a basic Barbie doll to use as a starting point for my 3D model. The first step was to scan this, a process that was fairly straightforward: the doll’s head was isolated, the hair tied back and cropped, and a button-head machine screw was hot glued inside the neck cavity. The threaded end of the assembly was then screwed into the scanner platform until tight, which enabled a precise 3D scan.

Three separate 360° scans were merged in this model.

NextEngine ScanStudio HD software was used to process the captured 3D data. This data was cleaned up in Rapid Works and then exported as an .IGS file for later use in 3D modeling software. Here is a quick KeyShot rendering of the unaltered .IGS file.

Daniel Brookman: Eye-Catching 3D Posters in East London

These paper posters were created by FOAM, a British agency that specializes in unique branded content for music artists and bands. The design began as a 3D model, which was then printed flat in component parts and hand-assembled.

project 1. Milling. Kali Moon

For this project, Milling, I made my face out of sculpey. I captured a facial expression of blowing a balloon and exaggerated it.
I got great image result from the laser scanner. From this experience of scanning the sculpture, I learned that I need to think about how the sculpture is attached to the scanner.
Before I created this object, I had to understand the relationships of undercuts as it relates to milling which needs to be done using NURBS. In the beginning, I was working with polygons which our milling software does not accept, so then I had to work again with NURBS in Rhino. For next project, I can use polygon in Zbrush which I am looking forward to having a fun time creating interesting work!

Andrew F. Scott: Laser Scanning Focus NURBS

In this post I will present a workflow for using the laser scanner to create elements for sculptural compositions. The illustration above presents the finished composition composed of a Nurbs Surface and linear contour elements.

The data was scanned in an earlier post Black Power Nkisi: Laser Scan. In that post the emphasis was placed on using Rapid Works to extract polygonal elements that could be used to create sculptural compositions. In this post the emphasis will be placed on using Rapid Works to derive a series of Nurbs elements that will be used in sculptural compositions.

The AutoSurface sub-menu is used to generate your Nurbs surface patches. You should focus on generating surface patches using both Evenly Distributed Networks and Feature Following networks. Once these patches are generated you have a variety of tools that can be used to edit the networks. Finally you can use your scanned mesh as the background for a networks that you create by drawing directly on its surface.

The finished surface typology is then imported in Rhino as an IGES file. Within Rhino the Curve From Object command is used to extract the contour curves from the nurbs patch network. Its always a good idea to organize your elements on separate layers so that you can access them when needed and its just good craftsmanship..

Grasshopper in invoked from within Rhino. Once in Grasshopper a simple script is created to read in all of the curves and transform them into adjustable pipes. Play around with the radius adjustment to play with the proportion of your tubes with the underlying mass and as an element unto itself.

The tubes should be baked into Rhino from within Grasshopper on separate levels.

The data can now be used in a wide variety of digital fabrication processes at a wide variety of scales. During this quarter I am teaching both Digital Applications in Sculpture and Direct Metal Sculpture. I look forward to exploring how these data sets and workflow can be used in both contexts.

7/14/2011 Update

Below are two of the initial studies based on the scanned data.

The first study is a serial exploration of the form. While I like the way that the cardboard looks I am interested in using this form as an internal armature. I want to see how well aqua-resin and cheese cloth works over this form. I am also interested in doing another serial study using wood.

In this study a 3d print of the computer model was created then molded using Smooth-On Rebound 25 silicone rubber. Afterwhich, urethane models were created using Smooth-Cast 325. I am interested in doing a few more castings and material explorations using these models. This is only the beginning.
