Daniela Guarin 3D Scanning and Rendering

My inspiration for the model I did was Flamenco. The movement of the skirt and the pose that the dancer acquires while perfoming.

The result was an organic and light sculpture, that is delicate and dynamic.
This is the original sculptey model with the alignment dots 

This is my original scan, after I converted into an
OBJ file and export it from RapidWorks to Rhino.

I reduced the amount of polys in my model. This
was done in rapidworks. This one is a wireframe view of a 1000-poly

Later I exported the original model into keyshot to experiment with texture.

Artist using 3d scanning

I found this artist Scott Carter on Colossal. His project Departing From the Rules of Harmony is especially relevant the work in this class. He shows some good process photos throughout.

Eddie Holecko: Project One, Digital Cleanup

Once the model was exported to an obj from RapidWorks, I imported the model into zbrush to clean up the polygons. 

Original geometry
Using the Dynamesh command in Zbrush, I evenly dispersed the polys throughout the object resulting in a much cleaner mesh.

I used Dynamesh in Z-brush to create several different high resolution and low resolution versions of the object.

191K polycount (left), 470k polycount (right)
After the model was exported as several obj files, I imported the low poly object into maya and experimented with creating a wire frame version.

Eddie Holecko: Project One, Process Photos

For this project, taking inspiration from H.R. Giger, I created a small WED clay sculpture.  The sculpt is roughly 4" tall so it works well with the 3D scanner's short range focus.

Next, the sculpt was sprayed with Kryolan Crystal Clear to seal the detail during the scanning process. The quick creature sculpt was then taken to the scanner.  I added several tracking points which make combining the geometry from each scan easier.

Positioning the sculpture is very important in order to receive a clean scan. If the sculpt/object is not in focus then the scanner does not read the geometry.

 In order to capture enough of the sculpture to work with in Rapid Works, Zbrush and Maya, I had to scan the object 360 degrees from three different positions.

Re-positioned sculpture
After the sculpture was scanned, I combined the scans from multiple angles to create one mesh.  I also cleaned up the geometry and cut out the metal pole that appeared in the scan. Then I imported the mesh into Rapid Works, where I patched a few holes in the geometry.  After the mesh was fused to one and completely patched, I exported an obj file.

Next, I imported the obj to Zbrush in order to clean up the geometry.  More information on mesh clean-up coming soon!

Eddie Holecko: Project One, Reference

I'm Eddie Holecko, junior visual effects major at the Savannah College of Art and Design. I love both sculpture and digital modeling and I look forward to this class because it integrates both techniques.  

Being interested in creatures and characters, I decided to sculpt and scan a maquette of an original creature inspired by one of my favorite artists, H.R. Giger. He is responsible for designing the very famous alien creature in Ridley Scott's film Alien.

Below are a few images of Giger's work.

Briana Mateo: Inspiration and Scanned Images

This is the process of how I made my clay man scan. Here is one of my sketches.
I started off with wood, aluminum foil and clay.

After it was made out of clay, I painted it white so the scanner could read it better.
Here are some images of some of my scans. In order to put the images taken by Rapid Works, I drew dots that would help put the images together.
Here are some photos of my serial stacked object next to the clay man.

Donovan.hettich 3D scanning exercise

1st post of scanning exercise a model is wire frame that i snipped from Rhino from a sculpture created by Professor Andrew F Scott .

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.
