I did not spend much time on GEM4D the past couple of months, as PhotoCoreLog took most of my time. The expiry date for Version 1.3.1 was set for 1 August 2013, so a new version was required to enable users to continue using GEM4D. Version 1.3.2 contains one correction and one addition:
The vertical clipping did not work as expected and was corrected.
DXF-support was added for the LWPOLYLINE entity sometimes exported by MineSight.
PhotoCoreLog is near completion, and data visualisation capabilities in GEM4D will then become my main focus.
