It's time to open a perijove-4 thread.
Voting is open for another two days. So, don't hesitate too long. Besides the discussion and the POIs on the mission page, you might consider John Roger's detailed discussion of several interesting features. If everything goes well, all instruments will be switched on. |

Here the first 170 frames of the same sequence as in the previous post, but de-Lambertianed according to the 1 bar Jupiter spheroid, and the square-root encoded resulting quotient stretched with gamma = 4.0:
jnc_pj04_109_10px_600x600_timelapse120_170frames_decompand_sqrt_deLambert_gamma4_v01.avi ( 1013.34K ) Number of downloads: 362 Contrast is considerably enhanced by this technique, but the Lambertian light model - at least my implementation - breaks down in the twilight of the terminator, and at the limb near the terminator. Björn Jónsson's model works considerably better. But of course, I'm ambitioned to find out where my technical limitations are regarding accurate modeling of Jupiter's lighting model. |
