Library of routines to facilitate creating better visualizations controlled from IDL, though not using IDL exclusively. Some routines use external applications such as ImageMagick and POV-Ray. Both direct graphics and object graphics systems are addressed; many routines calculate graphics system independent data like a set of vertices and connectivity list that can be visualized in either graphics system. :Dirs: animation/ routines and classes for creating animations animation/animators/ animator classes that perform some animation action animation/easing/ classes representing easing functions i.e. functions that control the rate of an animator color/ routines for dealing with specifying colors and color tables directgraphics/ helper routines for direct graphics flow/ routines for visualization of vector fields geometry/ routines for manipulating polygons and other geometric structures googlechart/ IDL interface to Google Charts API graphs/ routines for visualization of trees and graphs images/ routines for display of images lineplots/ routines for creating various types of line plots misc/ more in-depth examples of using vis library routines objectgraphics/ helper routines and classes for the object graphics systems povray/ routines to create POV-Ray renderings of data in IDL surfaces/ routines to visualize surface/elevation data svg/ routines for creating SVG (Scalable Vector Graphics) output tables/ routines for creating tables containing text and graphics text/ routines for handling text in graphics treemaps/ routines for creating treemaps, visual displays of weighted trees util/ utility routines for other routines vtk/ VTK file access library x3dom/ x3dom output from IDL object graphics
