Hi all,
Indigo 1.0.7 has been released:
win 32 bit:

EDIT:
win 64 bit:

This release focuses primarily on render quality.
Mitchell Netravali filtering for both splatting and super sample downsizing allows for reasonably sharp images with less aliasing than Gaussian filtering.
I've exposed 'blur' and 'ring' parameters (B and C from the M.N. model).
So you may tweak the parameters to get the kind of look you're after.
I recommend blur = 0.6, ring = 0.2 (this is the Indigo default)
Aperture diffraction may now be done in a filtering stage when the image is tone-mapped. This is called 'post-process diffraction'.
This technique, while not quite as accurate as during-tracing diffraction, can be faster, and will probably result in less noise in the render.
1.0.7
* fixed having to disable bidir for foreground_alpha
* fixed bug with render region complaining about image size
* Using inifile.xml instead of inifile.txt
* made it so that you can specifiy the blur and ring parameters of the MN splat filter.
* different sampling technique for non-circular apertures.
* made downsize filter and splat filter both be specified in similar ways.
* fixed aperture diffraction as a post-process
I'm probably gonna feature freeze until 1.0 stable.
Please point out any bugs.
Splat filter and downsize filter are set like so: (Either in inifile.xml, or in the renderer_settings element)
Code:
<downsize_filter>
<mn_cubic>
<ring>0.2</ring>
<blur>0.6</blur>
</mn_cubic>
</downsize_filter>
EDIT: attached a couple of images showing the difference between Mitchell Netravali downsize filtering and Gaussian. If you look carefully you can see the false frequencies (aliasing) introduced by the Gaussian filter. This is why you should use M.N. over Gaussian.
