3D Web Content was
an ETH World
project aiming at the easy acquisition of complex 3-dimensional objects
for web publication. Object acquisition is accomplished with commonly
available equipment: a DLP projector, a digital camera and a turntable.
The acquired virtual object can then be viewed and edited with Pointshop3D, a
software of the ETH Zurich Computer Graphics Laboratory. Beyond that,
virtual objects can be integrated into web pages by using a
technology developed within this project.
Acquisition
Our 3D
Scanner is based on the structured light
technique which requires a light source capable of generating various
vertical and horizontal stripe patterns. our implementation of
a 3D scanner intends to be low-cost, flexible and
practical. It consists of a projector, a camera and a turntable. The
object is put on the turntable and rotated to desired positions. For
each of these views, the object is reconstructed by the projector and
the camera using structured light. Both, geometry and texture are
reconstructed. Texture is reconstructed using either the Lambertian
reflectance model or the Phong model. At the end, the point-based
reconstructions produced by the single views are merged together to a
single model.
Web publishing
The acquired virtual object is stored as a set of surface elements or
surfels which are attributed points in 3D-space. Such surfel objects
can be easily integrated into web pages where they can be viewed with
all major web browsers under Windows or Linux. The
SurfelViewer
is realised as a browser plugin which is being developed within this project.
