Re: [PanoToolsNG] Re: VR Worx Object Movies
- I had to look at an old project to remind myself. There is a
resizable box in the dewobble window (actually on two different
images). Notice that one image is from zero degrees and the other
180. That is what you see when you click on the X button. Click on
the X' button and you see two images at 90 and 270 degrees. In other
words, you are looking at images 180 degrees apart in each of two
planes that are perpendicular to one another.
The normal usage, I believe, is to use the arrow keys to rotate about
until you see the maximum displacement of the center point of the
object from the center of rotation of the image. Note that the angle
you will see are still 180 degrees apart, but not 0/180 and 90/270
Set the resizable boxes to frame the image as it should be centered
in each view. Choose how to fill in any edges that are introduced by
shifting the images. When you build the object movie, the (hoped
for) result is that each image is shifted by the proper amount so
that they are all lined up.
Should work in concept, but it is tough to get right. I ended up
doing the same kind of thing you describe: making a semi-automated
process to center the images using photoshop. It was aided by the
fact that I had shot everything on chromakey and used Primatte to
remove the background.
