Wow, this is really clever. I've been thinking a lot about panoramic rendering -- that is, rendering panorama shots directly in a raytracer/raymarcher -- and I may take this technique more or less directly. When rendering with a ray-based approach (rather than raster-based), there should be no need to postprocess; simply map the globe onto the lens, and use that to determine your ray direction, making this lossless and effectively free.
Can't wait to play around with this -- great work!
- gavanwoolery 12y agoThe interesting thing about rendering a full (spherically-complete) panorama is that you can render the static aspects of the scene once, and you don't have to update until the view strafes in the XYZ direction (i.e. mouselook is free). I think this would be particularly useful for situations where you are locked in a seat (i.e. you could render the full cockpit once).
