01.10.11

• VTBuilder: correctly hides internal edges in World Map
• VTBuilder: improved support for ArcInfo BIL files to handle NOAA Globe files
• Enviro: allows any number of generic terrains in Data/Terrains
• Enviro: fixed display of Geographic coordinates
• Enviro: fixed skydome for very large Geographic terrains
• Enviro: fixed crash with Geographic terrains and Earth view

01.09.xx

• VTBuilder: display roads with width, when zoom factor is sufficiently high

01.09.04

• added 'TIF' as a supported file extension for Elevation Import in VTBuilder (for GeoTIFF elevation)

01.09.03

• improved vtTrackball with control of button assignments and zoom scaling

01.09.02

• move vtString from vtlib to vtdata (so that the lower-level classes can use it)
• preliminary implementation of library 'xmlhelper' (adaptation of 'expat' wrapper from SimGear)
• added module 'Content" to vtdata; stores, reads/writes list of 3D model content
• much development of ContentManager

01.08.31

• fixed crash with Nevada scene (was a non-standard PNG file, fixed by re-saving in DeBabelizer)
• initial definition of XML format for Content Manager file

01.08.30

• added vtMesh::AllowOptimize() to allow for certain objects (such as the Globe in the Earth view) to not use display lists, so that their vertices can be morphed dynamically
• fixed shading for Globe during morph
• fixed red terrain extents on Globe
• fixed lighting in vtosg
• further development on vtsgl (still not yet functional)
• reduced build times for Enviro
• started development of Content Manager

01.08.27

• GDAL port finished for vtdata / vtlib / Enviro / VTBuilder
• BT files now support an external .prj file, which allows for a huge number of projections

01.07.04

• began porting to GDAL for better support of more Elevation formats, and to reduce the number of development dependencies

01.06.xx

• ported to new version of wxWindows (2.2.7) and latest OSG development release

01.04.07

• Enviro: implemented support for the "MipMap" option in the terrain dialog, fixed the bug that all textures were previously mipmaped by default

01.03.10

• VTBuilder: added support for importing buildings from Shapefile point data

01.02.26

• made example of custom LOD algorithm (CustomTerrain)

01.02.24

• added support for reading/writing TerraGen .ter files

01.02.23

• Enviro: fixed problems with "lod method" choice control

01.02.22

• following the example of OSG, changed all projects to use DLL versions of the standard libraries, resulting in far smaller executables

01.02.20

• integrated changes from Unix compilation of TerrainSDK libraries
• upgraded to wxWindows 2.2.5 and OSG 0.8-38

01.02.16

• found and fixed a bug in the DLG reader, it was failing on certain LF-delimited DLG files with long header text

01.02.11

• support for flat roofs for buildings with concave footprints (although footprints with holes are still not handled)
• VTBuilder: improved building dialog, exposed "elevated" parameter
• Enviro: added picking of buildings, building dialog, ability to edit buildings properties at runtime

01.02.08

• VTBuilder: UI improvement: when deleting an elevation layer, don't forget current layer type (tricky semantics)

01.02.07

• VTBuilder: fixed problem in ProjectionDlg that was preventing selection of Datum type "Unknown"
• VTBuilder: implement importing of Water Layers from Shapefiles
• VTBuilder: implemented preliminary importation of Building Layers from Shapefiles,
  footprints and number of stories

01.02.02

• VTBuilder: replaced 2 more dialogs with better wxDesigner dialogs

01.01.24

• moved up to OSG 8.34, re-enabled terrain, re-enabled skydome

01.01.23

• fixed fading of detail texture (still not quite right?)

01.01.18

• added averaging to smooth the framerate a bit
• applied Ogren's optimization to McNally's split test
• fixed hip roofs
• Enviro: fixed enabling and checking of Terrain menu items

01.01.16

• expanded building color granularity to distinguish red/pink houses

01.01.15
