GeeXLab 0.14.1 released with Virtual Reality (VR) Support


After few months without new version, a new update of GeeXLab is available for Windows (32/64-bit), Linux (64-bit) and Raspberry Pi (32-bit). And the macOS version? The macOS version is still alive and I will simply build it later…

The main new feature of the branch 0.14.x.x is the support of Virtual Reality (VR) headsets via the OpenVR library. Like many other features in GeeXLab, the functionalities of OpenVR are available via a plugin (in the {GeeXLab_Home}/plugins/ folder). The OpenVR plugin is currently available for Windows platforms only but can be compiled on Linux too if necessary (to be honest I was too lazy to build the plugin on Linux…). I only tested the OpenVR plugin with the HTC VIVE headset and it’s a really cool experience! So if you have a VR headset, you will find some VR demos in the full code sample pack (in the gl-32/vr/ folder). I will explain how to code a VR demo in GeeXLab in a next post. As you will see, it’s easy!

I also improved a bit the error handling (syntax and runtime errors in scripting) and on Windows, GeeXLab displays an error scene. From GeeXLab 0.14+, a new log file is available for all scripting traces. This log file called _scripting_log.txt contains only scripting-related information. That allows to remove noise present in the main log file.

Other minor improvement is the support of Open True Type fonts (OTF) by the gh_font lib (lua / python). The Lua engine has been updated to the latest 5.3.4 version.

GeeXLab 0.14.1.x as well as the code sample pack can be downloaded from THIS PAGE.
