Smith Chart2006-06-24 11:54:20 AM delphi53 This is more of a general algorithm/math question. If you know what I a smith chart is this will make more sense. Lets say I have an equation for a set of circles... (x - R/R+1)^2 + (y - 0)^2 = (1/R+1)^2 This puts the center of the circles at ((R/R+1), 0) and a Radius of 1/R+1 R is between 0 and 1. I can map a series of these circles by sweeping R from 0 to 1 and then plot them on the screen. My question is how can I go the other way? Take the mouse postion and figure out what R is for the circle I am on in the window? This problem is easy if the circle centers were all the same. The catch is that the circle centers are a function of R as well. Thanks. Jim -- www.mustangpeak.net |
