[Flashcoders] Calc max radius of a circle

2005-11-22 Thread Robert Edgar
I am trying to calculate the max radius a circle can be and have it still fit in a bounding box. The difficult part of the question is that the circle is really a 3D object ie it can be rotate about the x or y axis. Ie imagine a plain circle drawn on the screen, now imagine your could "push" the

it will only affect the 'radius' measured along an axis perpendicular to the rotation axis..to calculate those values you can just take two points, one on each opposited edge of the circle, calculate where they are in 3d space then project them onto your viewing plane.. but are you also concer

The difficult part of the question is that the circle is really a 3D object ie it can be rotate about the x or y axis. A circle is a 2d object, do you mean a cylinder? The radius would always remain the same, 1/2 the shortest side of the box, or, if the box is aquare, call it 1/2 the wi

The difficult part of the question is that the circle is really a 3D object ie it can be rotate about the x or y axis. Do you mean rotate into the "z" axis? X and Y are still just 2-D spaces. 'rotating around the x-axis' is a perfectly reasonable statement for a 3D object: rotate someth
