Utilities to manipulate spherical images
License: Other
hello,
i'm trying to use envtoirr.c but when i convert (imagemagic tool) your cube.tif like this:
$> convert etc/cube.tif -depth 32 -define quantum:format=floating-point cube-float.tif
cube-float.tif looks ok in osx Preview.
$> ./envtoirr -n 128 -f cube-float.tif cube-irr.tif
Spherical harmonic coefficients:
0.09265 0.08183 0.05268
-0.02050 -0.02379 -0.01875
0.01137 0.01039 0.00868
-0.00058 0.00017 0.00088
-0.01319 -0.01128 -0.01012
0.00549 0.00483 0.00035
-0.00869 -0.00703 -0.00668
-0.01011 -0.00871 -0.01014
-0.00062 -0.00123 -0.00239
this values are so low and produce almost black irradiance map. I know it's probably problem in conversion, but tif format has so many options and i don't know what could be wrong. How should look like etc/cube.tif in 32bit float format? How do you convert to this format?
Hello. Could you please explain why if I apply remap to the rect picture, I get a fully circular dome, that can be used as a texture in a hemisphere 3D object:
./envremap -i rect -o dome etc/rect.tif out/out3.tif
However, if I remap the fisheye (hemi) to dome, I get half of circule projection:
Could you please explain how can I remap a fisheye 180 degrees picture to a dome image? So I can apply it as a texture to a 3D object:
In special, I am curious about the rect picture.
What camera was used to output this image?
I made a package for ArchLinux, but I couldn't find what license you'd like to use.
Right now it's listed as unknown
, which means the default copyright laws apply.
do you need if there are faster alternatives?
I need to transform rect to cube ๐
