For height feilds would it be possible to use bicubic patches to smooth
it out esp for low res ( spatial & colour ) height feilds in the
foreground of an image
&
using background { rgba <1,1,1,1>} (a for alpha) when outputing an image
should (if the selected file format supports it) add an alpha channel to
the image - this would be useful
&
Post-process - add a lens flare - I saw this done in a separate program
(command line) somewhere in the pov-links/Kens links - Not to take
anything from NKFlare & Colefaxe's lens include
&
a question - Is the post-process legal for submissions to the IRTC
