landmarker: An Introduction

landmarker consists of a collection of Tcl/Tk procedures that has been written and extended since 1999. The procedures use the Visualization ToolKit (VTK) library which is an open source, freely available software system ( www.kitware.com). The setting has been a multi-disciplinary research laboratory where engineers, dentists and medical doctors work together on projects involving analysis and visualization of 3-dimensional medical, mainly craniofacial, data. Often, there has been a lack of a tool for landmarking, inspection or manipulation of surfaces, and using VTK with Tcl as a script language has in many cases provided a reasonable customized solution with a reasonable amount of effort.

The main functionality of landmarker is a graphical user interface for manual point landmarking of surfaces.  It supports e.g. numbering/ordering/naming of landmarks; loading of predefined landmark sequence and names; saving/loading/editing landmark files. Other functionality: registration/transformation/smoothing/decimation/animation of surfaces, coloring based on input from external file, visualization of lines and curves, and more.
landmarker is free for non-commercial use as long as a reference (see below) is given in any publication to which it has contributed. Platform: Windows (Vista, XP, 2000).

A version for Linux will be added later.
