v1.12.1

Minor release to create a DOI.

v1.12.0

Changelog:

• Added support for exporting the scene to USD (Universal Scene Description) format which can be loaded into Blender or other DCC tools. Export from the menu entry File -> Save as USD or with the new viewer.export_usd() method.
• New z_up configuration option, if set to True the camera and default scene contents use the Z up convention, making it possible to visualize Z up data without changing coordinates.
• Added PyQt6 window type. Use AITVIEWER_INSTALL_PYQT6=1 pip install aitviewer to install PyQt6 instead of PyQt5 and set window_type = "pyqt6" in the configuration. This makes it easier to install and use aitviewer on MacOS.
• Added Meshes.from_file() constructor to create meshes from standard meshes file formats (.obj, .ply etc..).

Info:

• Changed from GPL-3.0 to MIT license.

v1.11.0

• Export scene to USD format.
• Added from_bvh method to skeleton class.
• Beta support for the SUPR model (https://github.com/ahmedosman/SUPR).
• Added SpheresTrail and LinesTrail renderable that allows to progressively build up a trail of lines or spheres as the sequence plays.
• viewer.center_view_on_node can now be used to center the initial viewing camera on a node from code.
• Video export can be configured to not add automatic integer suffixes. This will override existing video files of the same name.

Full Changelog: v1.10.0...v1.11.0

v1.10.0

• New multiple viewports feature. You can now split the viewport in a 2x1,1x2 and 2x2 grid (can be enabled from the menu View -> Viewports, or setting viewer.viewport_mode to "single", "split_v", "split_h" or "split_vh"), each viewport has its own camera and can be controlled independently, there are also camera presets for orthographic views from each of the main axis.
• New camera modes for trackball and first-person controls. (can be enabled from the menu Camera -> Control Modes, or setting the property viewer.camera.control_mode to "turntable", "trackball" and "first_person").
• Added camera trackball visualization (can be toggled from the menu Camera -> Show Trackball or by pressing B).
• Added new Lines2D renderable for drawing thin 2D lines.
• Added shadows on meshes with normal coloring enabled.
• Lights are now hidden by default, but can be shown checking the Show light property of the light in the Editor window, the light 3D model was also updated.

Bug fixes:

• Fixed artifacts when rendering objects with transparency in vertex colors or face colors, and with backface culling disabled.
• Fixed bug that broke the Plane renderable.
• Fixed a memory leak on window resize.

Full Changelog: v1.9.0...v1.10.0

v1.9.0

Changelog:

• New Volume renderable for visualizing dense SDF volumes (see new sdf_gpu_shader.py example). This new renderable implements a fast marching cubes algorithm on the GPU which allows for meshing large volumes (e.g. 512x512x512) in milliseconds.
• Upgraded to pyimgui version 2.0.0

Bug fixes:

• Fixed a bug that caused the animation range limits in the export menu to change while typing.
