Version 2.6.6 Build 2243 (22/11/2024)

Revision 2241

  • Added a scale to the bottom of the 3D View to make it easier to see at a glance how big the scene is. Implements #981.

  • Increased the space for some fields in the 3DM Analyst About box and the 3D View settings to avoid text being cropped on displays with larger font magnifications.

Revision 2240

  • Fixed the status bar display after digitising a Window feature in 3D View to show the correct values. Fixes #982.

Revision 2239

  • Fixed some problems reading .laz files introduced in Revision 2238.

Revision 2238

  • Added new support to load .laz point cloud data format. Implements #969.

Revision 2237

  • Fixed a bug to use the correct size DTM texture images for open tunnel heading projects in 3DM CalibCam. Fixes #983.

Revision 2236

  • Added a new rendering mode that shows the DTM wireframe over the top of the normal textured surface when the user zooms in enough. The purpose is to make it more obvious when the underlying surface model does not contain the level of detail required to map the features that the user is attempting to map. This can happen because the texture often looks more detailed than the surface model and creates the impression that small features can be mapped that are not actually present in the DTM. This new mode eliminates the need to turn the texture off and on or switch between Surface mode and wireframe mode to check the DTM. Implements #957.

    To activate this mode, simply click on the Show Triangles button while the Show Surface and Show Texture buttons are active. To deactivate, either click on the Show Triangles button again (returns to normal Show Surface mode) or click on the Show Surface button (switches to normal wireframe mode). To change mode between Show Surface and Show Triangles without activating the new textured wireframe mode, simply hold down the Ctrl key when clicking on the button.

    In addition to showing the triangulation overlaid on the DTM when zoomed in enough, the software will also warn the user of large triangles that should be used with care by highlighting them in yellow and using thicker lines than the normal DTM triangles. It will also colourise the inside of the triangle with a shade of yellow, with the shade being more opaque the larger the triangle is. At the moment triangles are highlighted in yellow if they have a side that is 8 × larger than the mean point spacing for all the DTMs currently loaded.

  • Added the current 3D View’s ground pixel size to the bottom-right of the window.

  • Updated the User’s Guide and added a PDF version to the software installation.

Revision 2235

  • 3DM Analyst now skips saving the texture image for any DTM saved in Surpac DTM format since it’s not used anyway.

  • Fixed a bug that prevented Surpac DTMs from being read, caused by the fact that Surpac and 3DM Analyst use the same extension for our respective file formats. Fixes #980.

Revision 2234

  • MessageBoxes are now centred vertically and horizontally on the monitor on which the software is running. The software previously assumed that the dialog would already be centred vertically and this led to the dialog being shrunk too much vertically when there was not much text to display. Fixes #978.

Revision 2233

  • Fixed a bug when loading a .pts file into 3DM Analyst, a blank error message would appear. Fixes #978.
