1 – Release Notes
GeeXLab 0.29.1.0 for Linux 64-bit is available with the following changes:
– an improved FFmpeg plugin with better video / audio synchronization. The frame seeking has been added so we can now step forward and backwards. FFmpeg is a powerful piece of code but its use can be very hard especially with audio/video sync and frame seeking. The audio playback is done by SDL2. This brand new FFmpeg plugin will the be core of an upcoming tiny video player made with GeeXLab.
– the PhysX 4 plugin has been updated with PhysX 4.1.1 SDK. The CPU PhysX should run faster on recent multicore CPUs because the detection of the number of available threads is now correctly done (only 4 threads were used in previous versions of the PhysX plugin).
– more keyboard keys have been added: KC_TAB, KC_ESCAPE, KC_RETURN, KC_DELETE, KC_INSERT, KC_HOME, KC_PGUP, KC_PGDOWN, KC_LSHIFT, KC_RSHIFT, KC_LCONTROL, KC_RCONTROL, KC_NUMLOCK, KC_LMENU and KC_LMENU.
– the Vulkan plugin has been updated with support of mipmapping, frame buffer reading for screenshots and few bugs have been fixed (buffer overflow, swapchain resize). To be honest, I didn’t tested the Vulkan plugin on Linux because I didn’t installed real NVIDIA drivers. I let the MESA 19.0.2 driver with GL 4.3 support only (NVF0 renderer). But the Vulkan plugin has been successfully tested on Windows. Let me know if you encounter problems with this plugin.
– new demos / code-samples are shipped with GeeXLab. These demos are available in:
{GeeXLab folder}/demopack01-gl21/ and {GeeXLab folder}/demopack02-gl32/.
Vertex pool / particles demo:
{GeeXLab folder}/demopack01-gl21/d09-vertexpool/
Shadertoy demo:
{GeeXLab folder}/demopack03/shadertoy/
Vertex pool / particles demo:
{GeeXLab folder}/demopack02-gl32/d01-geometry-shader-mesh-exploder/
GeeXLab 0.29.1.0 for Linux x64 has been compiled on Linux Mint 19.2 64-bit (MATE edition) with gcc/g++ 7.4.0 (GeeXLab app and all core libraries and plugins).
This version of GeeXLab is linked with GLIBC 2.27. If you have an older version of Linux, I added a folder in {GeeXLab folder}/dylibs/GLIBC-2.27/ with GLIBC 2.27 .so files. I don’t know if this will work but you can still try.
