OpenGL Extension Viewer

What's new in this version:

Surfer 21.2
New Features and Improvements:
- Axis: improve wording of error "Axis exceeds coordinate space"
- Options: Enable OpenGL hardware acceleration: update Help tip

Fixed:
- 3D View button is available when 2 Map objects are selected
- 3D View: 3D surface maps visibility tied to 'surface background' when another layer exits
- 3D View: certain vertical exaggeration values cause the camera angle to revert to default
- 3D View: grayed out when you have a 3D base
- Axis: manual scaling: improved warnings
- Contour map: contour fill is applied improperly for a specific grid
- Crash getting limits of Profile in Group when source deleted
- Crash when closing plot document
- Crash when closing Surfer
- Crash when going between 2D and 3D view windows
- Crash when undoing Reload Layer with Attribute Table open
- Error that the file contains an incorrect path when opening an SRF file and the data is not on the
- computer and then try to open data
- GDB import: "No geometry objects were found in the geodatabase" error upon import
- Internal Error after Grid Data because of invalid search parameters (gridder.cpp)
- Internal error opening file with 0 scale map transform (graphics3.cpp)
- Internal Error when adding base layer with extreme coordinates (axis.cpp)
- Internal Error when editing contour labels (uicontourlabeltool.cpp)
- Internal error when importing BLN file (and probably others) with infinite values (TrGraphics.cpp)
- STL files created in Surfer do not import with 3D geometry
- Swiss CH1903 LV03: incorrect WGS84 conversion factors (XYZ Displacement/Rotation)


Surfer 21.1
New Features and Improvements:
- 3D View: display 3D polylines, 3D polygons and 3D polymeshes in 3D
- Change To: convert regular points, polylines and polygons to 3D polylines and 3D polygons (and vice versa)
- Import: import 3D polylines, 3D polygons and 3D polymeshes as 3D geometry
- Properties: Coordinates: display and edit Z coordinates for 3D geometry
- Grids: calculate area and volume between contours
- 3D PDF Export: reduce file size of exported file using the grid surface "quality reduction"
- Display 32-bit BGRA images with or without transparency (turn off the alpha channel)
- DXF Export: option to export LWPOLYLINE with no ZLEVEL (2D flat polylines)
- Automation: all grid exporting/saving commands need an export options string
- Automation: ClassedPostLayer: new Class properties (including colormap)
- Automation: GridAssignNoData: use polygon boundary
- Automation: GridProject
- Automation: LabelFormat: DMSFormat and DMS options
- Automation: PointSample
- Automation: SaveFile [Grid]: use parameter for SpatialReferences

Fixed:
- 3D View: VRML Export: surface artifacts exist and blanked/NoData areas not removed
- Axes: Automatic Scaling should not default to something that gives you an error
- Axis Grid Lines: minor grid lines don't show up before first major tick
- Base from Data: doesn't import coordinate system information for data (e.g. from GSR2, PRJ)
- Base layer: Coordinates: when you move a polygon into base layer, the tracker isn't visible
- Convert Layer: converting to 3D surface creates empty map
- Coordinates Page marker tracker incorrect after moving shape within a Base Map
- Coordinates Page vertices do not update when moving shapes within a Group within a Base Map
- Crash after closing when displaying drop-down from Properties control
- Crash after pasting contour layer into base layer
- Crash in notifications when NotificationStatuses.txt has been altered
- Crash reports: thousands of ZIPs in Temp were created when report cannot be sent (connection issue, etc.)
- Crash when drawing filled contours after undo Break Apart
- Crash when Grid Data - Variogram after minimizing window
- Crash when Undo
- Endless Internal Error setting map scaling to 'inf' (axis.cpp, line 133)
- Export KML/KMZ: object IDs for point objects are not exported
- GPX Import Filter wasn't reading the elevation data
- Internal Error after closing a window (gscatch.cpp)
- Internal Error after creating 3D view (memorymappedcache.cpp)
- Internal Error after grouping/ungrouping objects (Scenelist.cpp)
- Internal Error when adding a profile over Z values with high number of sig digs (usertransform.cpp)
- Internal Error when converting a 2-grid vector to a 3D wireframe or 3D surface (iogrid.cpp)
- Internal Error when expanding Map and then delete (polygonnode.cpp)
- Internal Error when gridding data with Kriging (polarvariosurface.cpp)
- Internal Error when importing file with '%' character in filename
- Internal Error when opening a Surfer 7 SRF file with filled contours that have bad header info (contourfill.cpp)
- Internal Error when reshaping a polygon (reshapetool.cpp)
- Internal Error when Undo Order Change or Undo Delete (scenelist.cpp)
- Internal Error when undoing group with color scale after breaking apart layer (scenelist.cpp)
- Internal Error when undoing group, ungroup and reshape (gscatch.cpp)
- Internal Error with Grid Data using Kriging (kriginggridder.cpp)
- Internal Error: Grid Data: when loading settings for pages that don't use the settings
- KMZ import: File is stretched/wrong limits after import
- Objects are not grouping when the Attribute Table is open
- Open Grids: item added for each time you click on an open grid
