I spotted another type of faulty tile : ocean where there should be ground,
@ N47°56 W04°07
Check out Quimper's airport (LFRQ) : it's hovering over the sea.

I am interested in reports about straight ground tiles in the ocean or

Some locations in France (I give lat,long somewhere in the middle of the
faulty tile, and an airport nearby) :
Near Bordeaux
45.50 , -1.11 (LFCY, LFDK, LFIV)
45.08 , -0.67 (LFDU, LFBD, LFDY)
45.87 , -1.25 (LFCD)

Near Brest
47.93 , -4.11 (LFRQ)
48.18 , -4.62 (LFRL)

I hope you'll find without too much trouble the bug behind all this.

Cheers

One simple solution would be to add in the images on the website
something like "flightgear.org", maybe with a ©. That way :
 -> the fact that "someone" owns the right to this image is reaffirmed
to those who forget it
 -> "bad" usage like the one that started this thread is less of a
concern, since its provides potential buyers the information the
flightgear community would like them to know.
 -> it's easier to be nasty with "bad" users, since using the image
without permission is not legal (it's still true without this text, but
the rights' owner is unclear).

Of course, a license like CC would achieve that and more.

The real question we should address is : Does the seller provide the GPL
licence in the download, and does he provide, or offer to provide the
source code.
If he does, he can say whatever he wants on his website/publicity, there
is no GPL violation.

Assuming there is no GPL violation, this can only be done by contending
to Ebay that the screenshot in the publicity is a copyright violation.
(I'm not sure what is the right term in english : rough translation from
french of what I mean here is "author rights", which is what covers by
default any creative work in french law.)

So I think that the seller should be contacted to ask him politely if he
complies to GPL licence, and to point towards flightgear.org if he
wishes to continue to use those screenshots.

[Flightgear-devel] RTT issue with ATI cards (3d clouds)

2006-08-18 Thread Jocelyn Couetdic
Hi, I hope I'm posting to the right ml.
I tried to find out what was wrong with ATI cards, and the 3d clouds
code. For information, my system is a laptop with an ATI Mobility X700
graphics card. I run a debian testing, with a 2.6.16 "home build"
kernel, and I use the ATI proprietary driver (fglrx) version 8.27.10. I
also have a winXP, with which 3d clouds work well. I use flightgear
0.9.10

I did some quick and dirty debugging in the RenderTexture class (using
the TestRenderTexture program), and find out, that the reason it doesn't
work, is that neither GLX_SGIX_fbconfig, or GLX_SGIX_pbuffer extensions
are supported by the ATI GLX implementation :
$ glxinfo
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
GLX_ARB_multisample, GLX_EXT_visual_info, GLX_EXT_visual_rating, 
GLX_EXT_import_context, GLX_OML_swap_method,
GLX_SGI_make_current_read, 
GLX_SGIS_multisample, GLX_SGIX_hyperpipe, GLX_SGIX_swap_barrier, 
GLX_SGIX_fbconfig
client glx vendor string: ATI
client glx version string: 1.3
client glx extensions:
GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context, 
GLX_ARB_get_proc_address, GLX_ARB_multisample,
GLX_ATI_pixel_format_float, 
GLX_ATI_render_texture
GLX version: 1.2
GLX extensions:
GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context, 
GLX_ARB_multisample
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: MOBILITY RADEON X700 Generic
OpenGL version string: 2.0.5946 (8.27.10)
OpenGL extensions:
[snip]

This causes the initialize method of a RenderTexture object to fail
quite early on (in _VerifyExtensions()). As a result, the bbcache code
returns this during init :
"bbcache:Initialize failed, RTT not available for 3D clouds"

So here are a few questions :
-> I am totally off ? (I have absolutely no background in OpenGl
whatsoever). Is there somebody using those ATI driver, who can confirm
that those two extensions are not there ? (and that it's not some @#!%
driver installation bug on my system)

-> If this is indeed the problem, should someone file a ticket to ATI to
ask for support of those extensions in coming releases of the drivers ?

-> Or should the 3d clouds code be written to use the FramebufferObject,
which seems to be (from what I could gather on the net) a replacement
for older off-screen rendering and Rendering To Texture using pbuffers
extensions.
BTW, this GL_EXT_framebuffer_object is supported by the ATI drivers.

Regards,
