Re: 6 images (cube map) into equirectangular?

I'll check if I can use this script to automate the task of obtaining sub-frames from spherical frames of a video.

Re: 6 images (cube map) into equirectangular?

This looks interesting, but the script sphericalpano2cube can only "look" left, front, right, back, over, under; I'd need to be able to specify how many degrees to look "left" or "right" (not just 90° or 270°). The final objective is to constantly look (virtually) at the same object while moving par...

Extracting subframes from spherical frame

I have a 360° camera. I can view its images using an head mounted display, which shows a small portion of the whole image.
How can I use imagemagick to extract this portion, given looking direction and FOV?
Or should I use a different program?
I am on Windows 10.

Re: 6 images (cube map) into equirectangular?

I have a similar, but "reverse" need: I'd like to get multiple images from a spherical image. Each of the multiple images should show what I'd see looking toward a specific direction in the sphere. But I don't know which projections are involved, any help?

Re: Fisheye 235° to equirectangular

SED converter is not working on my system (Win7), it complains about some "garbage" being present in cim.txt.
I'll try with manual conversion described in last example.

Re: Fisheye 235° to equirectangular

I'm studying "Generic Mapping Tools" (GMT), Flexify Plugin, NASA G.projector, Marzipano tool,... but still can't figure out how to get what I need. :-(

Can Imagemagick create a "paper globe"?

Would it be possible to instruct Imagemagick to build one of these projections starting from an equirectangular one? http://globemakers.com/paper_globes/Paper_bag.jpg http://astropedia.astrogeology.usgs.gov/download/Docs/Globes/mars_mola_globe.pdf/full.jpg I tested several programs, but I could only...

From spherical to planar image

I shot a photo to a metal ball reflecting surroundings.
How can I turn this photo into an equirectangular projection for viewing it with panorama viewers?
Photo was shot looking at the sphere from bottom upwards.

Project a disk to a plane...

I have this image:
http://photojournal.jpl.nasa.gov/jpeg/PIA19932.jpg

I want to convert it into mercator projection; of course it will be just half the width of a full mercator projection, as it's just one emisphere, but it's ok for me.

How do I do that?

Since I installed Nokia OVI Suite I can't run any java program, as .JAR is nowassociated to "installation on phone"! :(

Re: Jigsaw puzzle solver

It works in Win7 Pro for me. In a DOS window just use the command: siftwin32 <book.pgm >book.key Pete This is very weird: of course I tried this example, but I always got a PGM file inside the .key file, and the program output itself said "PGM file created" or something like that. Now I just tried....
