1 – Release Notes
Yeah! GeeXLab is finally available on all supported platforms: Windows 64-bit, Linux 64-bit, macOS, Raspberry Pi and Tinker Board. The last time I updated GeeXLab on SBCs (SBC = Single Board Computer like the Raspberry Pi or the Tinker Board) was nearly one year ago, so it was time.
GeeXLab 0.28.1 has been developed on Windows 10 64-bit v1809, Linux Mint 19.1 64-bit MATE edition, macOS 10.14 Mojave, the latest Raspbian (2019-04-08 with kernel 4.14) and on the latest TinkerOS 2.0.8. Then, it should work properly on these environments.
GeeXLab 0.28.1 does not bring new big features, it’s more a maintenance / update release. ImGui and SQLite3 have been updated to their latest versions (respectively 1.70 and 3.28.0).
ImGui 1.70 adds an handy function to set the size of the next item: gh_imgui.set_next_item_width(). This function replaces gh_imgui.push_item_width() and gh_imgui.pop_item_width().
With previous GeeXLab you could set the size of a slider with the following code:
gh_imgui.push_item_width(200)
x = gh_imgui.slider_1f("##x_slider", x, min_value, max_value, power)
gh_imgui.pop_item_width()
Now you can do:
gh_imgui.set_next_item_width(200)
x = gh_imgui.slider_1f("##x_slider", x, min_value, max_value, power)
push_item_width() and pop_item_width() are still useful if you want to set the size of several items. But for one item, set_next_item_width() is there.
A new core plugin (a core plugin is a plugin that is embedded in GeeXLab like the Lua one) has been added to load glTF file formats. A new function has been added in gh_model lib to load .glTF directly: create_from_file_loader_gltf(). glTF files can now be loaded by the ASSIMP plugin or by this new plugin.
The Python 3 support has been added on Raspberry Pi and Tinker Board. On both platforms, the Python 3 plugin is linked against Python 3.5 libraries. Here is a quick overview of GeeXLab Python 3 support:
– Windows: linked with Python 3.7.3
– Linux: linked with Python 3.6 (shipped with Linux Mint 19.1)
– macOS: linked with Python 3.7.3
– Raspberry Pi: linked with Python 3.5
– Tinker Board: linked with Python 3.5
The Bullet3 physics engine has been updated on ALL platforms to its very latest version (2.88 / 2019.05.14). Bullet3 is now identical on all versions of GeeXLab.
