[gelöst] Linux-Frust ... vs ... Linux-Lust?

***soifz****

Is klar. Kann "blender" gar nie nicht können....
Und Leute, die in einem Forum helfen, woher sollten die wissen, was ein Einsteiger braucht, macht und alles kann.
Deshalb stellt er ja dort seine Fragen.

Merksatz: Alles, was digitale Geräte können, kannst du auch in Linux.
Wenn man es findet und gelernt hat.

Auf blöd aus einer Doku zu blender kopiert (ohne wirklich zu suchen, sondern nur "fisheye" gescannt:

One can use the following formula for fisheye fov calculation:
fov = 4 * arcsin (image size/(focal length * 4))
A 35mm film frame has the following dimensions: 24.3mm x 35.8mm (43.3mm diagonal)
Thus, for a 16mm fisheye on the 35mm camera in portrait orientation:
fov(y) = 136 degrees
fov(x) = 89 degrees
fov(diagonal) = 170 degrees
Note that the image circle produced by the 16mm fisheye lens is slightly
larger than the diagonal of the 35mm film frame, so Nikon's claim of
180 degree coverage may be fairly close to accurate, although the user
won't necessarily see that coverage on film.
The image sensor dimensions on the Nikon D1 series cameras are smaller
than the 35mm frame (which results in the effective focal length
magnification). They are approximately: 15.6mm x 23.7mm (28.4mm
diagonal)
Thus, the same 16mm fisheye lens on a D1x in portrait orientation yields the following fields of view:
fov(y) = 87 degrees
fov(x) = 56 degrees
fov(diagonal) = 105 degrees
The same formula can be used with the 8mm fisheye lenses. The difference
is that the 8mm lenses are true fisheyes, rather than full-frame
fisheyes like the 16mm. A true fisheye projects the full image circle of
the lens within the frame of the camera, so you wind up with a circular
image inside a dark field, rather than having the frame filled with the
image. Note however that these 8mm lenses are designed to be true
fisheyes for the 35mm camera format. The smaller sensors of digital
cameras such as the D1 series crops part of the image circle, so it is
no longer a true fisheye when used in this format.
The diameter of the image circle on an 8mm Nikkor fisheye (focused at
infinity) is approximately 23mm. (Note that the actual focal length of
most Nikkor 8mm fisheyes is about 8.2mm.) Thus, the circular field of
view inside a 35mm film frame is about 178-180 degrees.
However, when this lens is used on a D1x with its smaller image sensor,
the 23mm image circle is cropped on the short dimension to 15.6mm,
yielding a fov of about 114 degrees. The resulting image is a cropped
circle with 180-degree vertical coverage and 114-degree horizontal
coverage (assuming portrait orientation).
One final note... the FC-E8 Fisheye Converter made by Nikon for its
Coolpix line of digital cameras is often mistakenly referred to as an
"8mm fisheye." It is not, but it produces a similar rendering on the
Coolpix cameras to an 8mm true fisheye on a 35mm camera. As a
supplemental lens adapter, it is far more limited in its optical
quality, and any flaws or aberrations are magnified by the even smaller
image sensors used in most Coolpix cameras. It does produce a circular
image within the Coolpix frame, with a field of view between 184 and 186
degrees. Many photographers yield quite acceptable results with it. It
is a foundation element of most iPIX digital capture kits.
