[Flightgear-devel] RTT issue with ATI cards (3d clouds)
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, -- Jocelyn Couetdic [EMAIL PROTECTED] - Using Tomcat but need to do more? Need to support web services, security?
