Beginner needs advice for making first pano

  • Hi!

    I'm just trying out krpano tools for the first time and despite reading the documentation, I'm afraid I'm still a bit lost.

    I'm trying to make an indoor panorama, from 3d renderings - should I render out the 6 images for cubic panorama or what is the best way for this sort of thing?

    I already tried this by myself, following the kmakemultires tutorial (is that what I should be using?), but with default settings the walls of the room get "pushed" into the distance a great deal. I made a very simple test scene with a camera inside a 5m x 5m cube. The sides of the cube all have separate colors and the camera is set to have a fov of 90 degrees (correct?). The resulting pano gets really stretched as you can see from the screenshot - what am I doing wrong?

    Thanks!

  • should I render out the 6 images for cubic panorama or what is the best way for this sort of thing?

    I think this is the best way, as cubic panoramas feature the best viewing quality and the panotools use them anyway. Make sure you name them by this scheme, so the tools know how to align the cubefaces:
    "pano_l" - left
    "pano_f" - front
    "pano_r" - right
    "pano_b" - back
    "pano_u" - up
    "pano_d" - down

    If you want. :) It depends on what you want to do, but it's no mistake. Keep on practicing with it.

    The sides of the cube all have separate colors and the camera is set to have a fov of 90 degrees (correct?).

    Use a (much) lower fov value and try some fisheye settings. That should fix it.

  • Ah, you were talking about the fov of your 3D software, right? I meant the fov in the pano xml. The distortion of your pano is founded in a small resolution of your cubefaces, I guess.

  • That's not necessary for your example, your future panos will have a higher resolution anyway. So just use a smaller fov value in your pano.xml. The fov is in the <view>-tag:

    Code
    <view stereographic="true"
    		  fisheye="1.0"
    		  fov="150"
    		  fovmax="150"
    		  hlookat="0"
    		  vlookat="90"
    		  />

  • Hi,

    was a - maxpixelzoom="1.0" - setting (in the xml) and low resolution pano used in the first try?

    this would explain the large fov, because the zooming/fov was limited to avoid zooming the source pixels,
    just remove the - maxpixelzoom - setting and replace it with - fovmin="10", then the zooming/fov
    limit is independent of the screen and pano resolution,

    btw - yes, a fov of 90x90 degree is correct for cube faces,

    best regards,
    Klaus
