3D Scanning

This week we learned 3D scanning and printing, the mission is to design and 3D print an object that could not be made subtractively, and 3D scan an object and print it.

Make Sense of 3D

I first used the Sense 3D scanner. It is light, portable, and fast. With a chair being my turn table and a tripod to hold the Sense high, I scanned myself. It does not work very well with hairs. The complexity of hairstyles makes the 3D model complex and large. I should've cut to bald beforehand.

Projection Mapping

I am the TA of Krzysztof Wodiczko's Public Projection class this semester. We let the students create a performance or an installation that engages with a specific statue. To teach them how to project map to the face of the sculpture and to have a miniature version of the sculpture at hand for testing, I decided to use this 3D scan - print - MadMapper 3D object mapping pipeline to teach the students.
Wesley Buskirk has a very good tutorial on this here.

Pipeline

Design a digital 3d object (.obj file)
- Generate UV coordinates
- 3D print your digital object
- Setup your video projector
- Position your printed object and your projector
- Load the 3D object into MadMapper
- Calibrate the 3d object to the projector
- Fine tune
Add Effects
- Texture
- Live Lighting
- MADLines / Animated lines

Matter and Form

To better understand the limitations of 3D scanner, I scanned my iron gauge hat. This time I tried the matter and form scanner. It has a turn table on itself.

Shiny mesh

The iron gauge is very reflective and has holes in the mesh.

Projector-Drone Mount

I always want to try projection from a drone. So I printed the mount to hold the projector. Its quality will be tested next week.
