If any model with cameras is displayed in the 3D Viewer, a slider can
be used to filter the cameras that are being currently displayed based
on their resection IDs. This allows to visualize the order in which the
cameras have been added, and the groups in which they have been added.
Load EXR files in the 3D viewport as environment maps mapped on a sphere "attached" to the camera.
* improve exr loading strategy by considering depthmaps and env maps
* update to DepthMapEntity 2.1 (required to get the loading status)
Binding the "enabled" property of AlembicLoader's ObjectPicker to the parent MediaLoader's own "enabled" property caused invalid state where the loaded AlembicEntity was partially visible when toggling object visibility (since Qt 5.13).
In order to disable camera picking when AlembicEntity is disable, scale the camSelector component to 0.
This commit adds several components to centralize and extend 3D media loading. They are not yet integrated into Viewer3D. The entry point to this system is the MediaLibrary component that:
* can load N medias based on a filepath or load-and-watch node attributes
* provides a cache mechanism to instant-reload medias that were unloaded under certain conditions
* gives access to statistics (vertex/face/camera/textureCount) through a unified interface
