v0.24.alpha

v0.24.alpha Introduces new Images Sources, an ODE Cross Trigger, an ODE Accumulator, an ODE Heat-Mapper, and a new ODE Monitor Action.

Highlights

• There are now three (3) Images Sources, Single-Image, Multi-Image, and Image-Stream (Note: the Image-Stream can only be used with an Image Player at this time). See #737.
• The release includes six (6) new RGBA Color Types, most of which are dynamic and can be updated based on certain events or under client control. #745.
• There is a new ODE Cross Trigger for triggering on the occurrence that a Tracked Object crosses the Trigger's Line, Multi-Line, or Polygon Area. See #741.
• A new ODE Accumulator that can be added to any ODE Trigger to accumulate ODE Occurrences over all frames has been developed to replace the single purpose ODE Accumulation Trigger which worked on new object instances only. See #748.
• An ODE Occurrence Heat-Mapper has been added to accumulate, map, and display ODE occurrences based on location within the source frame over time. #761.
• A new ODE Monitor Action, that calls on a client provided callback function with a structure of complete ODE occurrence data can now added to any of the ODE Triggers. See #764
