1.2.0

What's new:

• TIN (Triangular Irregular Network) generation. Creation of a TIN using terrain layers and grid of points.
• Terrain layer, a new vector layer concept that contains objects that will be used as part of the TIN.
• The size and color of the points in the grid of points can be adjusted.
• The size of points in each point cloud can be individually adjusted.
• Color changes apply instantly.

Bug fixes and improvements:

• Fixed issue with .bpc files creation for projects with long names.
• The last folder path is selected as the default project folder.
• Support for projects with left-handed coordinate systems.

1.1.1

What's new:

• New tool: Rectangle point selection and point deletion.
• Increased Grid of points processing speed.
• Zoom to selection.
• User actions disabled during processing.
• Improved color of the Grid of points and Terrain filter results.

Bug fixes:

• Fixed bug with long Windows paths.
• Fixed INSUNITS units in the exported .dxf file. 
• Fixed irregular spacing of Grid of points at edges.
• Fixed Grid of points crash when using large point clouds.
• Fixed layer name validator.
• Fixed proxy authentication issue.
• Fixed coordinate system display for never classified points.
• Fixed vectorization unavailability for never classified points.

Known issues:

• Left-handed coordinate systems are not supported. Left-handed coordinate systems have the horizontal axes defined in the order Northing-Easting, instead of Easting-Northing. E.g. SWEREF99 TM (EPSG 3006), JGD2011 / Japan Plane Rectangular series (EPSG 6669 and following). We recommend to not work with such coordinate systems and use their UTM equivalents instead. Fixed in 1.2.0.

1.0.7

What's new

• Grid of points. Create and export with custom spacing on the original or classified point cloud.
• Change layer color, save a custom color, persist colors across projects.

Bug fixes

• Working directory typo.
• Fixed point size settings.

Known issues

• Left-handed coordinate systems are not supported. Left-handed coordinate systems have the horizontal axes defined in the order Northing-Easting, instead of Easting-Northing. E.g. SWEREF99 TM (EPSG 3006), JGD2011 / Japan Plane Rectangular series (EPSG 6669 and following). We recommend to not work with such coordinate systems and use their UTM equivalents instead.
• If Pix4Dsurvey 1.0.6 is installed, it needs to be manually uninstalled to install Pix4Dsurvey 1.0.7 on Windows.
• Very large point clouds may crash the software when using the Terrain filter process. Fixed in 1.1.0.
• If all point clouds are hidden, the Terrain filter process is disabled, although the Input point cloud parameter is set to All. Fixed in 1.1.0.
• Some proxies that need authentication with username/password might not work. Fixed in 1.1.0.
• Coordinates are not displayed for the Never classified points. Fixed in 1.1.0.

• Proxy settings, necessary for local network protected by proxies.
• Coordinate system update to GDAL 3.

Bug fixes

• Various bug fixes.

Known issues

• Left-handed coordinate systems are not supported. Left-handed coordinate systems have the horizontal axes defined in the order Northing-Easting, instead of Easting-Northing. E.g.
