Re: [Flashcoders] mathematics of an elipse
Given your points, Ivan is correct; however, although what I am about to write is most likely not going to be your case, there is a way of deriving it based on known dependencies. Given your points, it is possible if: * if the angle you had mentioned was the angle between the lines as they exist on the the original untranslated circle (in this case it is even possible if there is focal distortion by an unknown amount) * or if the ellipse will always be the type of ellipse where its opposing sides along the x and y axis are perfect reflection Yet, although the above makes it possible, these scenarios are most likely not your case. allandt bik-elliott (thefieldcomic.com) wrote: thankyou very much - i'll take a look best a On Thu, Jun 18, 2009 at 6:59 PM, Ivan Dembicki wrote: Hello Charles, You can build many ellipses through your points.

Does this help at all? Check the demo. http://code.google.com/p/bezier/ Charles P.

Hmmm Likely not, now that I am looking through it. I could have sworn it had a demo on angles and areas Charles P. On Thu, Jun 18, 2009 at 1:35 PM, Charles Parcell wrote: > Does this help at all?

[Flashcoders] mathematics of an elipse
hey guys I have have a maths problem that i'm having trouble solving, despite repeated attempts on Google. If i have an angle and a distance (n), plus one of the axis lengths (say the minor, y), how would i find out what the remaining axis length (x) was please? I've drawn it out here (let me know if the link fails - it has a limit) https://www.yousendit.com/download/cmczRFFlK3hLVlZMWEE9PQ Thanks A ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
