multi-threaded paging, where the Pager manages threads of reading local
and http files via seperate threads. This makes it possible to smoothly
browse large databases where parts of the data are locally cached while
others are on a remote server. Previously with this type of dataset
the pager would stall all paging while http requests were being served,
even when parts of the models are still loadable virtue of being in the
local cache.
Also as part of the refactoring the DatabaseRequest are now stored in the
ProxyNode/PagedLOD nodes to facilitate quite updating in the cull traversal,
with the new code avoiding mutex locks and searches. Previous on big
databases the overhead involved in make database requests could accumulate
to a point where it'd cause the cull traversal to break frame. The overhead
now is negligable.
Finally OSG_FILE_CACHE support has been moved from the curl plugin into
the DatabasePager. Eventually this functionality will be moved out into
osgDB for more general usage.
From Robert Osfield, refactored the FrameBufferObejcts::_drawBuffers set up so that its done
within the setAttachment method to avoid potential threading/execution order issues.
This is caused by the OSG_MSVC_VERSIONED_DLL hack.
there are hard-coded paths to place the dll's in the bin /dir that normally would go
in the lib/config (release/debug) dirs. Nmake has different locations for the files (no config dir).
fix: change the macro's in OsgMacroUtils.cmake for the IF(NOT MSVC_IDE) situation.
Libs go in lib/, and DLLs and executables go in bin/
To accopmplish this for MSVC_IDE the targets get a "../../bin" prefix,
for nmake this should be "../bin" (because there are no config folders).
This fix mimics the behaviour of the MSCV_IDE (visual studio) build system when building with nmake.
Note:
A change in the main CMakeLists.txt creates the needed plugin directory in the binary dir.
see included files for the changes:
r7885fix-v2/CMakeModules/OsgMacroUtils.cmake
r7885fix-v2/osgWrappers/CMakeLists.txt
r7885fix-v2/CMakeLists.txt
The behaviour of visual studio projects (and other build systems) remain unchanged.
Tested building and installing with nmake and visual studio 8 debug and release.
