<1.53>

15.08.02

• Enviro: Improve selection of abstract features.
  Add URL as default field on point features.
  Add popup menu for URL.
• VTBuilder: Enable GMS elevation import.
• VTBuilder: Update documentation of Dymax textures.

(yes, there is a 2-year gap here without development)

13.06.28

• removed ancient "Nevada" test/demo code

13.06.27

• more error-checking on the first time we parse an XML file

13.06.26

• fix ColorMap::GenerateColorTable to be re-callable (fixes Enviro's elevation legend colors), other tweaks

13.06.17

• Enviro: smoother orientation of the camera marker on the overview

<1.52>

13.06.14

• Enviro/vtlib: Roads: attempt to use a non-pavement texture for road intersections where the surrounding links are non-pavement.

13.06.13

• VTBuilder: improve Road Clean to ask for epsilon and clean link points within that distance

13.06.12

• Remove direct usage of netCDF library; we now call GDAL for those files instead, which works when GDAL has been built with netCDF support enabled.
• VTBuilder: Tin Layer Properties: Show 2D and 3D area

13.04.27

• vtlib: in SurfaceTexture::MakeDerivedTexture, check colormap before calling MakeColorMap, to respect vtTerrain::SetTextureColorMap

13.04.21

• vtlib: fix vtTerrainScene::BuildTerrain to call all the CreateStep methods.
• added vtTest to zip script
• moved config_vtdata.h include from QuikGrid.cpp to QuikGrid.h

13.03.03

• Changed CMake options to be prefixed with VTP_
• Minor compilation fixes to optional code

13.02.26

• VTBuilder standalone installer should include VTP\Data\GeoTypical folder
• vtlib: fix ocean texture clamping

13.02.21

• vtlib: fix Elastic to support terrains using tileset elevation

13.02.19

• Enviro: fix ephemeris dialog to not keep adding skydome images each time it's shown.

<1.5>

13.02.12

• vtlib: Safety checks for abstract layers that don't load.
• vtdata: Extend MakeRelativeToDataPath to handle subfolders of any data path.

• VTBuilder: fix crash on Utility layer saving, other tweaks.
• Enviro: drag-and-drop import of Image Layers.

13.02.08

• vtlib: Disable transform flattening on model load for now; some things like vehicles need the transforms intact.

13.02.06

• VTBuilder: Don't try to make any default buildings if we can't find the standard ones - this avoids a crash on bad datapath.
• Enviro: Respect locale in default time value in LocationDlg::OnPlayToDisk.

• Fix mouse events in wxSimple.

13.02.03

• vtui: fix StatePlane dialog which had wrong IDs for OK/Cancel

<1.49>

13.02.02

13.01.28

• vtlib: don't clamp textures on earthglobe since that causes visible black lines.
• Mac fixes.

13.01.26

• VTBuilder: Catch more cases of error reporting on GDAL import.

13.01.25

• vtdata/vtlib: Store road width in memory as a left and right width separately.
• VTBuilder: draw a center for roads with more than one lane, so you can see how left and right are different widths.
• vtdata: Buildings: got rid of another global s_Conv by putting it on the stack and passing it down.
• vtdata: added DRECT::SetInsideOut (useful for gathering extents), made TLink::ComputeExtent protected.

<1.48>

13.01.23

• vtdata: Fix vtHeightFieldGrid3d::ColorDibFromTable to always use true elevation.
• vtdata: added vtTin::GetTriangleNormal
• vtdata: added MakeRelativeToDataPath

13.01.20

• Enviro: Smoother progress during terrain creation (3 new steps).
• Many Mac build fixes.
• vtlib: Worked on TINs, texture from color, moved ColorMap table functionality down into ColorMap itself because we now use it in more than one place. Made vtTin3d (finally!) use the terrain parameters choice of color table.

13.01.18

• Enviro: Continued work on major re-arrangement of the Terrain Properties dialogs. Split out a new TinTextureDlg. Fixes to TIN picking speed.

13.01.17

• Enviro: Layer Dialog: Support 'activate' (double-click, enter) on structures as a shortcut for Zoom-To.
• OSM Import: Import id as a tag for every structure.

13.01.11

• VTBuilder: when importing a TIF of type Float32 or Int16, don't try loading it as an image before importing it as elevation.
• VTBuilder: show millimeters in extent dialog.

12.12.21

• Enviro: Add confirmation on exit, whether closed by Esc key, Quit menu, or Close box.
• Enviro/vtlib: Made vegetation a full layer type, so you can have more than one of them per terrain.

• Enviro: Add support for anti-aliasing (multisampling), exposed in global options dialog.
• Improved how GraphicsWindow is made with vtGLCanvas::InitGraphicsWindowWX.
• VTBuilder: Improve how it treats species files:
  • 1. When the user opens a species file, use the location of the default file in the open dialog, so they only have to press "OK" in most cases.
  • 2. If the user tries to load a plant file, and there are no species yet, ask them if they want to automatically load the default species, rather than just fail.
