Fledermaus 8.3.2 Release

3 March 2021

We are pleased to present Fledermaus 8.3.2 which is a maintenance release addressing a number of bugs and a few small enhancements.


  • You can chose to use Dynamic Lighting in the shading options for surfaces. Dynamic Lighting gives users the option to very quickly visually improve the appearance of the surface object loaded to Fledermaus map display. This features gives the surface the look and feel of the Fledermaus 7 default parameters (See Figure below).

Figure 1.  Screen captures of Surfaces with different Shading options. (A) Surface with QPS default shading (real physical shading), and (B) Same surface and location with Dynamic Lighting enabled.

The default shading parameters and options for QPS products is real physical shading. If you want to make use of the relative lighting solution, you need to go to the Shading options on the object attributes dock and toggle on Dynamic Lighting (See Figure 2). Note that the altitude and vertical scale variables from the lighting parameters, would then be relative values too. Please go to the Fledermaus 8 Reference manual to learn more about the shading parameters dialog.
