Overview
The ShapeAnnotator provides an interactive GUI for the inspection, segmentation and semantic annotation of 3D surface meshes. After loading a mesh and a domain of expertise formalized as an OWL ontology, the user may launch several segmentation algorithms to identify relevant surface features. Each such feature can then be annotated through an instance of an ontology class, and the set of instances can be saved to an OWL file.
The software provides all the means to create and edit the surface features. Also, a fully functional ontology browser is provided to seek the desired class to be instantiated to annotate each feature.
The ShapeAnnotator implements cutting-edge technologies to represent the semantics of 3D shapes, and is one of the main technological results produced by the EU-FP6 financed Network of Excellence
AIM@SHAPE.
Technical Aspects
The program is written in C++ and makes use of the JMeshLib API (
http://jmeshlib.sourceforge.net) to represent the polygon mesh internally.
Accepted input file formats are those handled by JMeshLib, namely:
OFF,
PLY,
STL,
VER-TRI (proprietary format used at IMATI-GE / CNR)
and partially:
VRML 1.0,
VRML 97,
OBJ,
IV 2.1
Go to
JMeshLib's page for details on partially supported formats.
If the input mesh is not manifold and/or not oriented, the loader automatically calls proper procedures to cut and orient the mesh, to triangulate non triangular faces, and to stitch together pairs of coincident boundary edges.
