Introduction
This chapter describes the Visualization Toolkit (VTK) data format. This data format is used by the VTK visualization toolkit developed by Kitware. VTK is a software system for 3D computer graphics, image processing and visualization. The VTK data format is the primary data structure used internally in Geocap, and as such is a basic component of more complex data structures such as those found in the petroleum or GIS industry. The VTK format combines a powerful data representation with a structure well suited to visualization.
Work in Geocap can be undertaken without detailed knowledge of VTK, although familiarity with concepts like data types, grids, and data attributes will enhance your understanding of data operations and display.
