Hi everyone,
This image was rendered in two passes using POV 3.7b24. The first pass
uses one area_light with the new area_illuminate keyword. All the
objects are height_fields. The second pass adjusts the contrast and adds
the bloom effect. The render time wasn't very high.
Questions and comments are always welcome~

Me too! I'd like to use area_illuminate with other features. Plus a
multi-threaded MegaPOV sure would be nice.

A comparison with a version of the image rendered without using that
keyword would be interesting.
The smaller the relative size of the area light with respect to the
object, the less effect area_illumination would have. The most prominent
difference can be seen when the area light is very large relative to the
object.
(What this means in practice is that area_illumination for relatively
small area lights is not very useful and only slows the rendering.)

An example of area_illumination is a sky_cube out of 5 area_lights for
ambient_occlusion (sorry for the underscores)

Okay, I've attached two jpegs. 'flake_SEM1_16' uses a standard
area_light and took 1m 16s to render. 'flake_SEM1_20' uses an
area_illuminate flag and took 1m 20s to render. They both use all the
same render settings, but the area_illuminate scene looks darker for the
obvious reasons. These images were not post-processed in any way.
I hope this was helpful.

Argh! Thunderbird is being a real beast today. I can't even reply to my
own message, or post more than one image at a time.
Here's the second image with area_illuminate....

By the way, I can reply to my own message @Thunderbird 2.0.0.9

I find "hope" to be very unnecessary and a waste of energy, kind of like no line
Successful compilations waiting for more code (windows):
3.6
3.6 upgraded to 3.61
3.61 patched with motion blur and stereo
megapov
Does this cygwin compile linux and unix programs on windows or just windows
programs in that environment?
