Hi... I've been trying to get FBOs working, but I have extremely limited time to work on such things, so I thought I'd just post my current patch here, and see if people can help me figure out what's wrong with it :)
FBOs (framebuffer objects) are a newer extension, intended to replace pbuffers to accomplish offscreen rendering - so instead of drawing to the screen, you get to draw to other objects, more importantly textures. We currently support pbuffers, but the code is sketchy, and disabled for that reason. SPEC: http://msi.unilim.fr/~porquet/glexts/GL_EXT_framebuffer_object.txt.htm
Known problems with this patch include:
(1) The D3D allows the user to setDepthStencilBuffer. I do no such thing - only a default depth buffer is supported. Neither is sharing this depth buffer between offscreen and onscreen [ requires copying of pixels via lock/unlock ]. Resolution: next revision - we don't support that onscreen in the first place :)
(2) Attempting to bind a framebuffer using GL_RGB32F_ARB, and GL_RGBA32F_ARB formats will fail on my hardware (Nvidia GeForce 6800GS) with error GL_FRAMEBUFFER_UNSUPPORTED_EXT, which means the format combination was invalid for implementation-dependent reasons. However, this doesn't make sense, based on information online, which indicates this should work. See: http://www.mathematik.uni-dortmund.de/~goeddeke/gpgpu/tutorial.htm : "Using textures as render targets".... or google. This is a problem, since certain demos which make use of the R32F format won't work with FBOs - but oddly work with pbuffers. See SoftShadowsII: http://www.humus.ca/index.php?page=3D&&start=8 On the other hand I know R16F -> GL_RGB16F works fine, based on 3Dc demo.
(3) Attempting to use GL_STENCIL_INDEX8_EXT in glRenderbufferStorageEXT will fail on my hardware with GL_INVALID_OPERATION. Why - this should work according to the GL spec. On the other hand this support list says otherwise: http://developer.nvidia.com/object/nv_ogl_texture_formats.html
========= Note that bugs or no bugs, the patch fixes the following (demos from humus.ca):
3Dc demo runs correctly TransparentShadowMapping demo runs correctly Sketch demo runs correctly Half-Life 2 startup screen runs correctly ---- Water demo offscreen content is moved offscreen SoftShadows2 - offscreen content moved offscreen, shows something a lot more correct PhongLighting - offscreen content moved offscreen ---- ...but doesn't quite match pbuffers, because:
SoftShadows2 - works completely in pbuffers (even if slow), has errors in FBOs PhongLighting - has errors in FBOs SelfShadowBump - no shadow artifacts on the wall, but now most of the demo's in shadow.

From: Ivan Gyurdiev ivg2@cornell.edu Date: Thu, 7 Sep 2006 07:17:00 -0400 Subject: [PATCH] Add support for offscreen rendering via FBOs.
This uses: GL_EXT_framebuffer_objects
A select_offscreen_mode() function was added, where FBOs are given precedence over pbuffers - another way to do offscreen rendering, which is older, not as nice, and currently disabled at compile time.
A shared depth buffer between offscreen and onscreen is not currently supported. A custom depth buffer (SetDepthStencil) is not supported (but onscreen doesn't support it either). --- dlls/wined3d/device.c | 201 +++++++++++++++++++++++++++++++++++----- dlls/wined3d/directx.c | 17 +++ dlls/wined3d/utils.c | 38 +++++++- dlls/wined3d/wined3d_private.h | 70 +++++++++----- include/wine/wined3d_gl.h | 1 5 files changed, 275 insertions(+), 52 deletions(-)
