Default Bug??, difference???

First to say that I have followed the first way of install the drivers at http://ubuntuforums.org/showthread.php?t=301499 the Guide for Ubuntu Feisty 7.04 that guide me to the method 1 in http://doc.gwos.org/index.php/Latest...eisty#METHOD_1

Also a guy on IRC before I restart the graphics server instruct me that I do http://ubuntuforums.org/showpost.php...0&postcount=16 for a missing file in the official repos... (libfbw)

I have watched correct behaviour!!!, It is working OK. I have an 8800 GTS 320Mb.

But Im starting learning Ogre and Cg I have installed Ogre from source and also do some symbolick links for satisfy CGtutorial (complain a lot of some file like libpng0.2 where I have 0.3 http://ubuntuforums.org/showthread.php?t=474538 )


Here is the link to the post in Ogre forum

http://www.ogre3d.org/phpBB2/viewtop...=231031#231031

Also I put a link to an http://video.tleyotlocelocoatl.googl.../ogre1divx.avi



My actual thoughts are:
  • Cgtutorial complain about and WGL extension (WGL_NV_render_depth_texture)
  • Perhaps Ogre is also searching the same extension???
  • the only display of extensions containing *depth_* in glxinfo are (they are the same for the ogre log): GL_ARB_depth_texture, GL_EXT_depth_bounds_test, GL_EXT_packed_depth_stencil, GL_NV_copy_depth_to_color, GL_NV_depth_buffer_float, GL_NV_depth_clamp, GL_NV_packed_depth_stencil, GL_SGIX_depth_texture
  • I suppose that Cgtutorial should not search for WGL_ extensions... even there isnt any extension that has that prefix in the glxinfo or ogre log.
  • I can not arguee to what happen with Ogre in this regard more than perhaps is searching the same extension than Cgtutorial
  • is a problem with the driver like stated by an answer in the ogre forum?

is the extension GL_ARB_depth_texture, is this 1 the equivalent to WGL_NV_render_depth_texture????

8800 is able to support that specific demo??? I mean the choice in the demo of the texture shadows Depth shadow map and (PCF)??
