GeeXLab 0.48 Released for Windows, Linux and Raspberry Pi OS (Updated: v0.48.3.0 for Windows)

GeeXLab: scriptable proto-engine for Windows and Linux




1 – Release Notes

This new version of GeeXLab is available for Windows 64-bit, Linux 64-bit and Raspberry Pi OS 32-bit. I compiled the Linux version on Linux Mint 21 and the consequence is that GeeXLab for Linux is now linked with GLIBC 2.35.

Update (2022.09.15)
GeeXLab is a maintenance release and updates several libraries like Assimp, cglft, Python, SQLite 3 and FFmpeg. I’m currently working on the support of Intel Arc GPUs in the GPU monitoring plugin, that’s why new functions like get_gpu_eus() are popping up in the gh_gml library (GML = Gpu Monitoring Library). They are not functional yet but it’s just a matter of time…

Update (2022.08.12)
GeeXLab fixes and improves the drag and drop on Linux. I tested GeeXLab on the latest Kali Linux 2022.3 and I wasn’t able to drag and drop demos from Thunar (default file manager on Kali). I debugged my code during several hours and I finally found the bug in the management of the XdndEnter message (a pointer was incorrectly cast). I wonder how this code was able to work with other file managers… Now, the drag and drop should work anywhere. I tested with Thunar 4.16.2 (Kali Linux), with Dolphin 22.04.2 (Linux Garuda) and with PCManFM 1.3.2.

Update (2022.08.11)
GeeXLab for Linux has been compiled on Linux Mint 20.3, then GeeXLab is now linked again with GLIBC 2.31. Why ? Because I wanted to test GeeXLab on the new Kali Linux 2022.3 and it didn’t work because Kali uses GLIBC 2.33…

GeeXLab 0.48 comes with new functions to render 3D models with transparent surfaces in the gh_model lib: update_meshes_lists(), render_opaque_meshes() and render_transparent_meshes(). Thanks to these functions, you can render transparent surfaces after opaque ones and have a better control on the depth test and color blending when rendering transparent surfaces.

The OpenGL renderer supports features like GL_ARB_create_context_robustness or GL_ARB_create_context_no_error. To enable these features, just add to the XML window node the following attributes:
gl_context_no_error="1" gl_context_robustness="1"

I updated some OpenGL 3 shaders (in Lua and Python libs) to make them running with Radeon GPUs + Adrenalin 22.7.1.

And nice news, the Vulkan plugin works on Raspberry Pi 4! More on this news in an upcoming article.
