## Revision as of 23:07, 21 July 2009

- include antialiasing interpolators
- add a r^4 term to the a*r^3+b*r^2+c*r+d distortion correction (because the r^4 term like b*r^2 has correct symmetry whereas a and c terms are largely unphysical)

- Why that? The formula applies to the radius of the image, which means it is always symmetrical. a and c terms work great to correct for special types of distortion (wavy one f.e.) --Erik Krause 22:07, 21 July 2009 (UTC)

- allow simultaneous use of both flatfield polynomial and dustmap file
~~implement orthographic projection (benefits from antialiasing interpolators)~~implemented in Hugin 0.8.0 Klaus 16:51, 21 July 2009 (UTC)
