Andrew F. Scott: Scanning Exercise01

This is my posting of My Scanned Image. The Image is based on an African Nkonde Figure.

I will be using it throughout the quarter to explore digital fabrication processes. To see Other works that I have created using this subject you can go to my Flickr page.

Andrew F. Scott: Material Studies

Scanned Rhino Model in rhino

I had the opportunity to do a little more form exploration on the previous model from laser scanned data.  Within Rhino I used the nurbs surface tessellation as a cue for the surface activation of the model. Using pipes i created a series of sweeping linear forms across the surface of the model.

Mahogany

Polished Oak

I began with a series of monochromatic compositions using a single material I wanted to get a feel for the rhythmic movement of the lines across the surface of the material.

Mahogany with Cherry

 This led to an exploration of a combination of materials. This is where the fun really begins as you can begin to play material properties with and against each other.

Gold with Pearl

 I really like this combination of materials because it begins to suggest a form that can operate on a diversity of scales.

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.

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.

Irina Pljusznyin:NURBS Modeling: Toroid Forms

These are some of the print screen shots that I made during the process of creating the model. Since it looked much like an ear tried other methods. Therefore instead of starting in Rhino I started in Maya, and used the sculpting tools to create my new shapes and new approach.

Irina Pljusznyin:Nurbs Modeling

For the NURBS modeling project I was inspired by an image that I have found for to be my concept in my architectural studio. I was trying to create a shape that shows the metamorphosis of a sphere, that is not going to become a full sphere, but shows the journey through different sequences. The materiality I would like to use to further develop the project after it is printed is metal-like.

CJ Miller: GOARAX in Progress

GOARAX

In my experience as an artist, I have always found that the best way to master a new skill is to have fun with subject matter while you're in a rookie, experimental phase. In Andrew Scott's Digital Application in Sculpture 450 class, I am creating a 10 ft serial stacked sculpture of a winged lion. My inspiration comes from classical sculpture which adorns buildings round the world with imagery of mythical beasts and mythology. Gorax will be comprised of 231 18x32 sheets of luan, and the physical effort put into constructing him will mean many, many hours of vigilantly lining every numbered piece up correctly, and clamping and gluing it all together. additionally fabricating the remaining parts from printed patterns created from the rhino program.

Andrew F. Scott: Mobius Stripped:

Irina inspired me to go home and work out this problem for creating mobius strips. Deconstructing the problems in its simplest terms yields a line rotated about a closed circular path 180 degrees from start to finish. Thankfully Maya has two powerful commands that can be used to accomplish this easily. Attach to Motion Paths> allows you to attach a curve to a path. It also alows you to generates keyframes for the curve's orientation as it moves aling the path. In this case the rotation at 90 degrees and at 180 degrees. Once completed you can then use Create Animated Sweep> to generate the lofted surface for your mobius strip. You can create output as Nurbs or as a Polygonal Object, and that's where the fun begins. This solution was inspired by a Jose Sanchez tutorial: The Mobius Strip from GSAPPonline at Columbia University. It provides a good start. A similar technique can also be used to generate shell forms. I have extended some of the concepts covered in the tutorial which will be explained in an upcoming tutorial video on using animation for modeling in Maya.

Thank you for helping me get the work to here!
Prof Scott is the BEST!
