# Distance Calculation - from Isometric view

I need a lot of help with this one. I uploaded an image so you can see what I am talking about because I know this will help explain what I am trying to do.

I made an isometric world and am trying to calculate the distance from the center to the outter edge of the circle (or map). The red dot in the middle is the middle. Looking at the image its obvious that the green line is longer than the blue line, yet BECAUSE its an isometric world, the distance is exactly the same. Right? So here is the real problem: How do I calculate, or determine, the distance of the orange dots from within red dot in the middle? I know it isn't using the a^2 + b^2 = c^2 method - because that doesn't relate to isometric stuff. My guess is some how using angles, but I have had no luck :(.

What do you guys suggest, and can you provide some small snippets to help me? Many thank yous

if that's an ellipse, you can calculate the distance from your orange point to the center and multiple by the ratio of the major axis divided by the distance from the center to the ellipse perimeter along the segment that intersects your orange point and center.

nice :) (i knew you'd hit this one, lol)

here's my 'limp' animated demo version, using a couple of known ratios of the conic plane, in relation to an actual circular region: FLA

...does it, but not very elegant ;)

i'm pretty predicatable. i can not resist any questions about math.
