FTL Mixer App
Ability to mix and merge multiple ftl recordings using a separate app. Features should include:
- allow two or more ftl files to be specified.
- select sources to take from each file
- specify any transformation to apply to the pose
- specify any scaling to camera intrinsics (for a scaling effect?)
- adjust timestamps
Another option is to allow reconstruct app to directly load multiple FTL files.
Separately, the ability to have source groups within a single FTL file is needed, allowing reconstruction to occur only between sources belonging to the same group. Similarly, reprojection may also need to check for source group. This may need to be a separate issue, but needs to be considered when doing the ftl merge.
Reconstruct may also need more options to make particular sources transparent or otherwise tinted.
