|

|

The new osgTerrain library and associated osgdem utility program allow users to uses moziacs of geospatial imagery and digital elevation maps
|
||||
to generate a complete paged database which can be used with standard OSG viewers, and users programs. By utilising GDAL to load the imagery
|
||||
and DEM's a wide range of geospatial formats are supported.

The TerraPage plugin has also been rewritten ontop of the OSG's osg::PagedLOD and osgDB::DatabasePager which provides support for

tile fallback mechansim to ensure that no holes or cracks appear in the databases being roamed, and to achieve constant frameframe

via load balancing mechansisms with osgDB::DatabasePager.

Double Vec & Matrix classes & CoordinateSystemNode/EllipsoidModel class have been introduced to better support browsing of large

osgUtil has been enhanced with a improved triangle stipper class (osgUtil::TriStipVisitor), a new simplifier (osgUtil::Simplifer) for
|

reducing triangle density of osg::Geometry leaves (utilised by osgTerrain to provide simplication of terrain tiles), improved and

more configurable optimizer (osgUtil::Optimizer), a new utility class for compling and releasing OpenGL objects (osgUtil::GLObjectVisitor)
|

replaces the prevsous and more limited DisplayListVisitor.

All the osgGA::MatrxManipulator's (used for camera manipulator etc) have been revamped with usage of doubles internally, and with
|
||||
tracking of the current CoordinateSystem if one is active, to be better support whole earth databases. All the MatrixManipulator
|
||||
have been extend to allow the setting of a user defined a home position. Two new manipulators have been introduced
|

osgGA::TerrainManipulator, for roaming whole earth/terrain databases, and osgGA::TrackerManipulator which allows the camera to be

Movie support under Linux and OSX via libMpeg3 and Quicktime respectively, which extend the new osg::ImageStream base class which

allows application developers access to playing, pausing and rewinding movies.

The convertion utility osgconv has been extended to allow compression of textures and mipmap generation during conversion when
|
||||
writing to the native .ive binary format. Texture compression and pre computer mipmaps enable faster loading of databases
|

and lower utilization of memory resources.
