Panorama Exporter Render Setup Dialog 167
Inter face
Output Size group
Choose one of the predefined sizes or enter
another size in the Width and Height fields (in
pixels). These controls affect the image’s
aspect
ratio (page 3–1005)
.
Width and Height—Lets you set the resolution of
the output image by specifying the width and the
height of the im a ge, in pixels.
Preset resolution buttons (512x256, 1025x 512, and
so on)—
Click one of these buttons to choose a
preset resolution.
Aper ture Width—Lets you specify an aperture
width for the camera that creates the rendered
output.Changingthisvaluechangesthecamera’s
Lens value. This affects the relationship between
the Lens and the FOV values, but it doesn’t change
the camera’s view of the scene.
For example, if you have a Lens setting of 43.0 mm,
and you change the Aperture Width from 36 to
50, when you close the Render Scene dialog (or
render), the camera Lens spinner has changed to
59.722, but the scene still looks the same in the
viewport and the rendering. If you use one of t he
preset formats r ather than Custom, the aperture
width is determined by the format, and this control
is replaced by a text display.
Options group
Atmospher ics—Renders any applied atmospheric
effects, such as volume fog, when turned on.
Effects—Renders any applied rendering effects,
such as Blur, when turned on.
Displa cement—Renders any applied displacement
mapping.
Video Color Check—Checks for pixel colors that are
beyond the safe
NTSC (page 3–1074)
or
PAL (page
3–1082)
threshold and flags them or modifies
them to acceptable values.
By default, "unsafe" colors render as black pixels.
You can change the color check display by using the
Rendering panel (page 3–863)
of the
Preference
Settings dialog (page 3–859)
.
Render Hi dden Geometry — Renders all geometric
objects in the scene, even if they are hidden.
Area/Linear Lights as Point Lights—Renders all area
or linear lights as if they were point lights, speeding
up rendering time.
Tip: This is useful for draf t renderings, as point
lights render much faster than area lights.
Note: Scenes with
radiosity (page 3–50)
are not
affected by this togg le, as area lig hts do not have a
significanteffectontheperformanceofaradiosity
solution.
Super B lack —
Super Black rendering (page 3–1112)
limits the dar kness of rendered geometry for video
compositing.
