2  What is Explorer3D ?

Explorer3D is an interactive visualization software. It allows object spatial positionning in a 2D or 3D space, based on various projection techniques:

• When attribute-value files are given, Explorer3D relies on dimensionality reduction, either supervised (e.g. linear discriminant analysis) or unsupervised (e.g. principal component analysis).
• When a distance file is given (distance -or dissimilarity- between pairs of objects), Explorer3D relies on multidimensional scaling.

Various unsupervised classification tool are available, in ordre to help the user’s graphical interpretation.

Explorer3D is globally oriented towards an interactive use, in order to allow for subset extractions, positionning constraints, ...
