Published by kaufManu over 2 years ago

aitviewer - 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.

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.

aitviewer - v1.2.0

Changelog - The viewer can now display overlay 3D data onto RGB images which are rendered as texturized billboards. Weak perspective and OpenCV camera models are available. Check out the VIBE example for a demo. - Cameras are now objects in the scene. Multiview camera systems can be displayed. - The target of the viewing camera can be displayed. Hit T to show it. By holding Shift and scrolling, the target is displaced together with the camera (instead of the camera moving closer to the target when not holding Shift). - Unified GLSL shaders. - Hitting Esc will no longer directly close the viewer. - Spheres are now using the Meshes class under the hood. - Flat shading and edge drawing options are no longer global, but per object. Can be toggled via the GUI for Meshes objects. - Various other bug fixes.
