  1. What aspect ratio does a standard equirectangular panorama use?
    • 1:1
    • 16:9
    • 2:1
    • 4:3
  2. Why does an ordinary image generator often leave a visible seam in a panorama?
    • It treats the left and right edges as unrelated borders even though they are the same place in the world
    • It always outputs images at too low a resolution
    • It cannot generate sky or horizon content
    • It adds a watermark along one edge
  3. Where is distortion strongest in an equirectangular image?
    • In the exact center of the image
    • Along the horizon line
    • Evenly across the whole image
    • In the top and bottom rows near the poles
  4. Why does a 360 panorama not feel fully 3D in a VR headset?
    • Headsets cannot display equirectangular images
    • It captures a single viewpoint, so there is no parallax when you move your head
    • It is always rendered in black and white
    • It is limited to 180 degrees of view
  5. Maxay ka qabataa suufka wareegtada ah ee qaabka fidinta?
    • It crops the image into a circle
    • It adds a black border to hide the seam
    • It pads each side edge with pixels from the opposite edge so the network treats the image as a horizontal loop
    • It rotates the image during generation
  6. Why do some pipelines convert a panorama to a cubemap before fixing the poles?
    • Cube faces have no equirectangular stretching, so ordinary inpainting works on the top and bottom faces
    • Cubemaps store more color depth
    • Game engines cannot read cubemaps
    • Cubemaps automatically add parallax
  7. Why might an AI-generated skybox look wrong as a lighting source for realistic reflections?
    • Skyboxes cannot contain the sun
    • Renderers ignore environment maps
    • Generated images are always too dark
    • Most generators output low dynamic range images, while renderers expect high dynamic range environment maps
  8. What is a quick way to check a panorama for a seam?
    • Convert it to grayscale
    • Shift the image horizontally by half its width
    • Flip it upside down
    • Reduce it to a thumbnail
