| | 6 | >>> support for and generation of large scale geospatial whole earth databases, support for movies, with examples shadows and volume rendering. |
| | 7 | |
| | 8 | The 0.9.7 encompasses many improvements, bug fixes, new examples and significant new functionality, the most notable of which is |
| | 9 | a new osgTerrain library for generation of large scale geospatial databases. |
| | 10 | |
| | 11 | The new osgTerrain library and associated osgdem utility program allow users to uses moziacs of geospatial imagery and digital elevation maps |
| | 12 | to generate a complete paged database which can be used with standard OSG viewers, and users programs. By utilising GDAL to load the imagery |
| | 13 | and DEM's a wide range of geospatial formats are supported. |
| | 14 | |
| | 15 | The TerraPage plugin has also been rewritten ontop of the OSG's osg::PagedLOD and osgDB::DatabasePager which provides support for |
| | 16 | tile fallback mechansim to ensure that no holes or cracks appear in the databases being roamed, and to achieve constant frameframe |
| | 17 | via load balancing mechansisms with osgDB::DatabasePager. |
| | 18 | |
| | 19 | The osgDB::DatabasePager has been further improved to provide more configurable load balancing to allow application developers to |
| | 20 | achieve constrant framerates when using paged databases. |
| | 21 | |
| | 22 | Double Vec & Matrix classes & CoordinateSystemNode/EllipsoidModel class have been introduced to better support browsing of large |
| | 23 | scale databases, and to provide a mechansim for tracking the local up orientation when roaming whole earth databases. |
| | 24 | |
| | 25 | osgUtil has been enhanced with a improved triangle stipper class (osgUtil::TriStipVisitor), a new simplifier (osgUtil::Simplifer) for |
| | 26 | reducing triangle density of osg::Geometry leaves (utilised by osgTerrain to provide simplication of terrain tiles), improved and |
| | 27 | more configurable optimizer (osgUtil::Optimizer), a new utility class for compling and releasing OpenGL objects (osgUtil::GLObjectVisitor) |
| | 28 | replaces the prevsous and more limited DisplayListVisitor. |
| | 29 | |
| | 30 | All the osgGA::MatrxManipulator's (used for camera manipulator etc) have been revamped with usage of doubles internally, and with |
| | 31 | tracking of the current CoordinateSystem if one is active, to be better support whole earth databases. All the MatrixManipulator |
| | 32 | have been extend to allow the setting of a user defined a home position. Two new manipulators have been introduced |
| | 33 | osgGA::TerrainManipulator, for roaming whole earth/terrain databases, and osgGA::TrackerManipulator which allows the camera to be |
| | 34 | attached to a node in the scene graph. |
| | 35 | |
| | 36 | Movie support under Linux and OSX via libMpeg3 and Quicktime respectively, which extend the new osg::ImageStream base class which |
| | 37 | allows application developers access to playing, pausing and rewinding movies. |
| | 38 | |
| | 39 | The convertion utility osgconv has been extended to allow compression of textures and mipmap generation during conversion when |
| | 40 | writing to the native .ive binary format. Texture compression and pre computer mipmaps enable faster loading of databases |
| | 41 | and lower utilization of memory resources. |
| | 42 | |
| 37 | | |
| 38 | | New manipulators - TerrainManipulator and TrackerManipulator. |
| 39 | | |
| 40 | | Movie support under Linux and OSX via LibMpeg3 and Quicktime respectively. |
| 41 | | |
| 42 | | Support for compressing textures and mipmap generation in osgconv. |
| | 62 | |
| | 63 | Write support added to JPG plugin. |
| | 64 | |
| | 65 | Write + 3D texture support added to DDS plugin. |
| | 66 | |
| | 67 | Pseudo loaders .trans, .rot and .scale have been added. |
| | 68 | |
| | 69 | Updated LWO, AC3D, BMP, IVE and FLT loaers. |
| | 70 | |
| | 71 | osg::TexGenNode has been added to provide a mechanism for positioning OpenGL's texture coordinate generation planes. |
