Summary: atmospheres of planets get transparent when going away from planets in celestia Product: Mesa Version: unspecified Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/R600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: acelists@atlas.sk

Created an attachment (id=39071) --> (https://bugs.freedesktop.org/attachment.cgi?id=39071) Far view of Titan - atmosphere transparent

The atmosphere of some planets (not all) gets transparent when approaching the planets. As intended, the atmosphere of Titan should be opaque at all distances (except when standing on the surface). However, currently it gets more transparent as the observer is moving AWAY from the planet. From the distance, atmosphere is invisible, near the planet it is opaque.

This did not happen in Mesa 7.8.2.

Any chance you could bisect it?

--- Comment #8 from aceman acelists@atlas.sk 2010-10-03 11:03:38 PDT --- I have tried it, and managed several iterations. But now I have hit a range where celestia crashes on start with this error: celestia: radeon_texture.c:703: radeon_store_teximage: Predpoklad `dstRowStride' nesplnený. (Prerequisite `dstRowStride' not met)

I have tried to get out of this range using "git bisect skip" on hundreds of commits, but I was not successful.

If you can help me get out of this hole I could continue bisecting.

Driver broken for hundreds of commits? Sounds weird... Could you try "make distclean" and "make realclean" and then compile previously-broken-commit?

--- Comment #12 from aceman acelists@atlas.sk 2011-01-12 12:30:22 PST --- After trying bisecting mesa 7.9 and finally returning to the official snapshot, the problem vanished at the planet. It is still visible at some nebulas, but I am not sure it is the same problem. Both seem like a problem with some depth (distance from screen) determination.
