Status

Technical page for tracking the status of the changes introduced in the fork in hopes to update it to 3.6.5 in future.

Present upstream or was cherry-picked from there

• getGLExtensionFuncPtr: support gl4es wrapper on Android.
• Explicit signed char declarations for portability.
• added dxtc support in Image::getColor...
• Add compatibility for type 1 (uncompressed colour-mapped) targa files
• Reversed the order of some sizedInternalFormats enum entries...
• Add CMake options to control which osgPlugins/ are built
• Add CMake option to not build deprecated serializers
• Fix collada build error
• OcclusionQueryNode: do not retrieve the query result before it's available
• Fixed warning
• Check for presence of occlusion query extension
• osgParticle: override vector interpolations in LinearInterpolator
• osgParticle: avoid unnecessary Matrixf <-> Matrixd conversions
• Remove dynamic_cast in Drawable::UpdateCallback::run
• Remove dynamic_cast in osgFX::Technique...
• Remove dynamic_casts in osgParticle
• Remove dynamic_cast in TransformVisitor
• Add OSG_USE_FLOAT_QUAT option for single precision quaternions -- off by default

Redundant

• Fix invisible stats graph due to the node being culled -- the commit that breaks it is only present in its own branch and not the main branch.
• Disable ffmpeg plugin -- most likely
• Fix bug in osgFX::Effect introduced by 94dc5b1 -- same commit
• Build with Qt4 by default, if available, rather than Qt5 -- redundant since there's no osgqt in 3.6
• Remove thread affinity setting in ViewerBase -- 3.6 feature that works around the issue is used now from the side of OpenMW

Uncertain

• Don't mess with the cmake defaults for build postfixes + Added back "d" postfix for debug builds -- I dunno if it's that important
• osgParticle: dynamically allocate _particles -- removing vertex arrays breaks mp3butcher's shader-based particles
• Disable COMPILE_WITH_SHADOW_OCCLUSION_CULLING by default
• Extended checks for COMPILE_WITH_SHADOW_OCCLUSION_CULLING

Potentially useful

• Remove dynamic_cast's in UpdateVisitor::apply(Drawable&) -- it's that same old "backwards compatibility breaking" commit
• Added virtual method Node::isOccluderNode -- adapted commit (which adds asOccluderNode) is only present in master and not OpenSceneGraph-3.6 branch, but should probably go there anyway
• Float quat/matrix/plane usage -- obviously can't be upstreamed

Things that should be cherry-picked/done particularly in case we're unable to use 3.6.5

• TGA reader improvements -- Robert fixed its memory leaks AnyOldName3 introduced that we still have and then AnyOldName3 extended its support to all known TGA formats
• DDS palette indexed pixel format reading support -- we still want to have it to improve mod compatibility.
• Maybe see if we can make cluster culling callback configurable to fix its behavior on our RTT cameras
• Rebase 3.4 branch against 3.4.1 stable release or just upstream 3.4 branch proper -- currently it's based on a RC revision
• Probably a lot more things, I'll ask around
