v1.3.0

Changelog

• Support for variable size point clouds and per-point colors.
• Object selection and interaction with mouse left click. Use K key to lock the current selection. If you don't want any selection, unselect everything (by clicking on the background or the floor) and then hit K. The selection lock is also accessible via the menu bar View > Lock Selection.
• Per object context menu with mouse right click.
• Additional alternative mouse interaction: Use middle mouse to rotate and Shift plus middle mouse to pan.
• Drawing of object outlines.
• Edit mode for SMPL models which enables interactive editing of joint angles.
• New video export GUI and export options.
• New ROMP and DIP examples.
• Support for multiple active cameras for MultiViewSystem.
• Optimized uniform color update for Meshes.

Bug fixes:

• Handle NaNs in bounding box computation.
• Correctly handle transparency for VariableTopologyMeshes.
• Fixed a bug when accessing SMPL faces.

PRs

• Object selection, SMPL joint editing, Export GUI and bug fixes by @ramenguy99 in #7

Full Changelog: v1.2.0...v1.3.0

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.

What's Changed

• Camera models, MultiViewSystem, Billboards and bug fixes by @ramenguy99 in #6
