Each curve was discretized separately, as a way of getting smooth results without wasting (1994-era) computing time on well resolved regions. \r\n\r\nThe Carleson grids, as far as I can figure, rely on standardly discretized curves. Each curve's discretization size depends on its radius, though.\r\n\r\nWegert's phase plots, which are beautiful, rely on just a meshgrid style array of point values. \r\n\r\nAny of the plots are easy to produce, as long as you don't insist on an evenly spaced grid in the __user__ domain. How you would visualize a map from, say, one polygon to another is open to question. \r\n\r\nPhase plots seem to be better than SCT plots, though exponential crowding may change that tune. In a sense Carleson plots produce the most information, but they are an acquired taste and much more complicated to support. The @ehkropf implementation has overridden the adaptive capacity of gridcurves in order to make them work. \r\n\r\nIt may be that we need a factory class for grids that can produce different types of plots for different types of data. Visualization is so important to the package that we have to get this right.\r\n\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/tobydriscoll/conformalmapping/issues/comments/69290949","html_url":"https://github.com/tobydriscoll/conformalmapping/issues/53#issuecomment-69290949","issue_url":"https://api.github.com/repos/tobydriscoll/conformalmapping/issues/53","id":69290949,"user":{"login":"tobydriscoll","id":3577518,"avatar_url":"https://avatars.githubusercontent.com/u/3577518?v=3","gravatar_id":"","url":"https://api.github.com/users/tobydriscoll","html_url":"https://github.com/tobydriscoll","followers_url":"https://api.github.com/users/tobydriscoll/followers","following_url":"https://api.github.com/users/tobydriscoll/following{/other_user}","gists_url":"https://api.github.com/users/tobydriscoll/gists{/gist_id}","starred_url":"https://api.github.com/users/tobydriscoll/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/tobydriscoll/subscriptions","organizations_url":"https://api.github.com/users/tobydriscoll/orgs","repos_url":"https://api.github.com/users/tobydriscoll/repos","events_url":"https://api.github.com/users/tobydriscoll/events{/privacy}","received_events_url":"https://api.github.com/users/tobydriscoll/received_events","type":"User","site_admin":false},"created_at":"2015-01-09T04:11:21Z","updated_at":"2015-01-09T04:11:21Z","body":"Try checking out feature/improve-plots and then \r\n\r\n```\r\nplot(ellipse(1,2,.6))\r\nfill(unitdisk)\r\nfill( between(circle(0,2),circle(0.5,0.5)) )\r\n```"}}
