GeeXLab 0.29.2 released for all platforms: Alpha to Coverage added, FMOD and WiringPi Support Updated




GeeXLab 3d prototyping for Win64, Linux64, macOS, RaspberryPi and TinkerBoard



 

1 – Release Notes

GeeXLab 0.29.2 comes with the following changes:

– support of Alpha to Coverage for all platforms in OpenGL: Alpha to Coverage is not a new feature in OpenGL but it was missing in GeeXlab. And I needed this feature in a new demo I worked on these last days (grass rendering).

– support of FMOD on all platforms: so far, the FMOD plugin was only present on Windows, Linux and macOS. Now it’s also available on Raspberry Pi and TinkerBoard. FMOD is a powerful sound system and now it’s easy to play sounds (mp3, waw, xm, s3m, etc…) on any platform.

ImGui library updated to latest version 1.73 (released today!)

WiringPi 2.52 on Raspberry Pi: WiringPi is the reat lib that makes it possible to access the GPIO connector of the Raspberry Pi. I forgot to check updates of this lib in previous versions of GeeXLab. WiringPi 2.52 is the latest version of WiringPi and comes with full support of Raspberry Pi 4. WiringPi is included in the latest Raspbian but it’s an old version: 2.50, the RPi 4 being not fully supported. I was a bit sad to learn that WiringPi 2.52 is the last version: WiringPi’s author, Gordon Henderson, has decided to stop the public version of WiringPi because of too many … fu*k*ng assholes that don’t respect his amazing work on WiringPi. Gordon has posted an article that explains why: wiringPi – deprecated. I don’t understand why the Raspberry Pi Foundation doesn’t help Gordon, this situation shouldn’t exist.

I updated GPIO demos that are shipped with GeeXLab for RPi (in the demopack02/rpi_gpio/ folder ). All those demos are based on WiringPi. The following screenshot is the demo_v1.xml that uses gh_rpi.gpio_get_board_info() to get information about the Raspberry Pi hardware.

Last thing: GeeXLab for Raspberry Pi works only on Raspbian Buster because it’s linked with GLIBC 2.28. My test version of Raspbian Stretch has GLIBC 2.24. If you really need GeeXLab for Stretch, let me know, I will try to find some time (no guarantee) to recompile it for Raspbian Stretch.

 
GeeXLab 0.29.2 is out, and now, it’s time to release new demos, articles and apps based on this version 0.29.2 😉

 

2 – Changelog

This changelog is intended for all versions of GeeXLab.

Full changelog from beginning of time is available HERE.

Version 0.29.2.0 - 2019.09.25
+ (2019.09.25) [RaspberryPi / TinkerBoard] FMOD plugin added!
! (2019.09.25) [RaspberryPi / TinkerBoard] enabled multisampling support (GL_MULTISAMPLE).
+ (2019.09.25) [RaspberryPi] updated WiringPi with latest version 2.52 (including RPi 4 support). 
! (2019.09.25) updated ImGui with latest version 1.73.
! (2019.09.25) [Windows] updated GPU Shark 0.14.1.1
+ (2019.09.24) [OpenGL renderer] added support of GL_SAMPLE_ALPHA_TO_COVERAGE and GL_SAMPLE_ALPHA_TO_ONE in gh_renderer.enable_state().
! (2019.09.24) [FMOD plugin] updated with latest FMOD Core SDK version 2.0.4 on Windows, Linux and macOS.
! (2019.09.24) [FMOD plugin] added FMOD_CREATESAMPLE to sound creation. This flag forces the decompression at loadtime, decompressing or decoding whole file into memory. It's the fastest for playback.
* (2019.09.23) fixed a bug in libs/lua/gxl.lua and libs/python/gxl_utils.py: the addressing mode was not set in set_sampler_params().

    Thanks, I will look at that issue asap.
    But it’s weird, because I built GeeXLab on macOS 10.15 (mac-mini with an Intel GPU) and it worked perfectly.
