How it works:
Slicer: This is a tool to make rendering faster and
circumvent file size limitations. Instead of rendering the
complete horizontal FOV, a "viewing window" with a smaller FOV is used. The Slicer then generates multiple partial
project files by "dragging" this "viewing window" through
the panorama, only showing the actual region of interest you
want to render.
This only works for cylindrical and equirectangular
panoramas: As long as your pitch doesn't change, the
distortion caused by the projection is independent of the
panorama's yaw.
For rectilinear panoramas it makes a difference if you move
the center of the panorama, so slicing won't work and the
application will inform you about that.
Multiplier: If you have made many panoramas with a
repeatable setup (e.g. a precision head or an automatic
setup), it can be very time consuming to load each image set
and apply a template.
The multiplier will do that for you in an automated way.
Load the template project and point to the image directory.
All images in this directory will be read in order, grouped
and for each group, a separate PTGui project will be
generated. Those projects can then be rendered in one go by
dragging them on the PTGui batch stitcher.

Gigapixel Slicing
(PTGui and Hugin projects)
Switch to "Slicer"-Tab and define number of parts the
panorama should be sliced into. Optionally,
define overscan to enable better blending of critical image regions
(you have to cut away those pixels after the rendering). E.g. defining
an overscan of 1000 pixels will add 500 pixels on the left and 500
pixels on the right.
If you want to directly convert the slices to a complete
HDView panorama, set the according option to have a batch
file created that will do the job by running the batch after
stitching has completed.
Now, generate the slices.
The sliced panorama projects are created in the input
directory with an ending in the form xxx_slice00.
You can now drag the sliced projects onto PTGui batch
stitcher or use the automatically generated Hugin batch file.
The output images will be created in your defined rendering
directory in the form xxx_slice00.
Hidden
feature: If you want to define a non-standard number of slices or overscan, you can double click the number above the slider. Note: This
number will not be checked for validity... |
PTGui Multi-Template Apply
(PTGui projects only)
Switch to "Multiply"-Tab. All relevant parameters are
already calculated according to your template project: "Source image
type" is a file filter for apply-able source images.
You can use it to only select file types or to create a more
complex search mask, e.g. "img12??.jpg" is also a valid
filter criteria.
"Include subdirs on read": Subdirectories will
also be crawled.
"Include directory name": If checked, all files
will be referenced absolute, e.g. "c:\temp\img1234.jpg"
instead of "img1234.jpg".
This option is automatically enabled if you include subdirs.
"Re-read EXIF date for images": All
input images will be read and the EXIF date in the PTGui
project file will be corrected, so all stitched panoramas
will show the correct shooting date.
Now, start the multiplier.
The generated panorama projects will be saved in the
directory of the input project.
The name is assembled from the first input image and the
number of images in the panorama project, for example
"img1234 with 4 images.pts"
