WHAT'S NEW Robert L. Park Friday, 6 Jan 06 Washington, DC DEEP SPACE CLIMATE OBSERVATORY KILLED. http://bobpark.physics.umd.edu/index.html -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Hi
Sharing some nice results I had with interpolating EPIC images and projecting then on a planar map (equirectangular). https://vimeo.com/207296528/b9b8eee67c The video is at its optimal quality, in 4K resolution and 120Hz.. The images are generated in real-time as I stream the EPIC images (and their metadata) from the NASA website. Interpolation is made by simple blending of perspective projection on a 3D ellipsoid model of the Earth, executed in the GPU via a custom fragment shader. Good enough to look almost like optical flow. The conversion from 3D ellipsoid model into equirectangular map is also done in real-time, via a vertex shader on the GPU. Here is another video from my Blueturn app (freely available on all platforms), that shows better the transition between spheric and planar. https://vimeo.com/207296473/28f01f0807 Enjoy! |
