View Change 1.0 --------------- REQUIREMENTS: VMD Version 1.4 or newer DESCRIPTION: Provides four commands which can be used to save and restore VMD eye viewpoints, and smoothly interpolate between them. PROCEDURES: save_viewpoint - save current viewpoint restore_viewpoint - change current viewpoint to a saved one move_view - smoothly move between saved viewpoints (see Warning) write_viewpoints - write viewpoints to a disk file (read back in via 'source') BUGS: Warning: this script does the math cheaply, i.e. only interpolates transformation matrices, many sorts of extreme viewpoint changes will look odd to bizzare. This is often cured by segmenting a drastic camera move into smaller ones DOWNLOAD THE FILE: view_change.tcl AUTHOR: Barry Isralewitz
