Bend Precision
polycounter lvl 13
Hi, how to measure circle length so that one can model straight on a planar surface and apply bend of 45 degrees (quarter section) without moving bend modifier gizmo parallel in either direction which is the most common method and then adjusting the vertices at curved end. (Thiago method like) Also I plan to keep it all within power of 2.
P.S I ll be testing out measure utility in max but I doubt it ll work due to typical udk grid setup.
P.S.S Sorry if my English dont make sense, its early morning where I am and this has not made me sleep properly either.

So I quickly tested out measure utility on a 512 diameter circle and it gives you 1608.483 length just as I was expecting it to be , not precise power of 2. In theory I should be able to work with 1/4th length of it, bend and mirror 3 times and call it a day. But it ll take up weird texture space on texture sheet. Haha people will wish I should not be their tech lead now.
Anyways so made half of it (804.241) bend it and symmetry, now it should be 512 diameter precise but no
s = length of segment
r = radius of circle
theta = angle in radians (2*pi radians = 360 degrees)
ex. 512 diameter circle = 256 radius
45/360 = x/2pi therefore x = pi/4 radians or 0.785....
s = 256 * pi/4 = 64*pi = 201.0619298 length of segment
Radians are another way of measuring angles but they have no units. 360 degrees equals 2*pi radians. The 45/360 = x/(2*pi) bit is just a ratio conversion of 45 degrees to the equivalent radians.
