Since we can have per-pixel lod we should also honor the filter per-pixel (in fact we didn't honor it per quad neither in the multiple quad case). Do this by running the linear path and simply beating the weights into shape (the sample with the higher weight is the one which should have been chosen with nearest filtering hence adjust filter weight to 1.0/0.0 based on that). If all pixels use nearest filter (either min and mag) then still run just a nearest filter as this is way cheaper (probably around 4 times faster for 2d, more for 3d case) and it should be relatively rare that pixels really need different filtering. OTOH if all pixels would require linear don't do anything special since the linear path with filter adjustments shouldn't really be all that much more expensive than ordinary linear, and we think it's rare that min/mag filters are configured differently so there doesn't seem much value in trying to optimize this further. This does not yet fix the AoS path (though currently AoS is only used for single quads hence it could be considered less broken, just never honoring per-pixel filter decision but doing it per quad). v2: simplify code a bit (unify min linear and min nearest cases) Reviewed-by: Jose Fonseca <jfonseca@vmware.com> |

File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons osmesa mesagdi to build classic mesa Windows GDI drivers; or scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. 1) install python 2.7 2) install scons (latest) 3) install mingw, flex, and bison 4) install libxml2 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get libxml2-python-2.9.1.win-amd64-py2.7.exe 5) install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe 6) install git 7) download mesa from git see http://www.mesa3d.org/repository.html 8) run scons General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
