360 and Panoramic Image Generation Quiz

Answers and explanations appear as you take the quiz.

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. What does circular (wraparound) padding do in a diffusion model?
   • 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
