Dalai Felinto 8c4fa687e0 Cycles bugfix: AUTO wasn't working for Equisolid Fisheye lens 
Now one no longer needs to match the sensor dimensions with the render dimensions manually.

IMPORTANT NOTE: if you were using AUTO before with mismathing sensor aspect ratio (comparing to the render dimensions)
this will change your render! We can doversion this, but apart from Tube project I don't know if anyone else
is using this yet (part due to this bug and the only recently fixed 3dview preview aspect ratio).

That should help more artists to take advantage of this fantastic Blender feature.
It still helps to know the parameters of kwnown cameras/lens though.
For example:

Nikon DX2S with a 10.5mm fisheye can be set with:
Render resolution: 4288 x 2848
Sensor 23.7 x 15.70 (15.70 can be ommitted if AUTO is used as fit method)

Note: some cameras render different sizes according to the recording mode.
For example, a Red Scarlet in 5k (@12 fps) can render a full circular fisheye with a sigma 4.5 lens.
The same camera in the 30fps recording mode renders 4k in a cropped circular image.
So it's not only the resolution that changes, but the actual sensor been used.

So just keep in mind that the more information you have from the camera/lens you want to emulate the better.

util_attribute.h Fix for Cycles (CUDA) compilation (again ...). Moved the AttributeStandard enum typedef and the attribute_standard_name mapping function to util_attribute/util_types headers, so they can properly be used by kernel and render files alike. This should avoid any std C includes which are not available in CUDA. Thanks to Sergey for help! 2012-09-07 11:06:45 +00:00
