Abstract

PEGS is a prototype 2 dimensional editor for grid selection. This version deals with the positioning of boundary and mesh points. The user can:

• mark or erase mesh points
• distribute points over a connected set of lines
• slide points along a line, or across maIiy lines
• expand a portion of the figure for more visual precision
• save a set of mesh points
• load a set of mesh points
• erase the current figure and draw a new one without changing the points
• overlay a new figure without changing the points
• move or spin the figure

Currently, one cannot generate grids on the IRIS, but must send the set of points to another computer. Once the grid has been obtained, the resulting image (and points) can be loaded into PEGS and the points edited.
