The CAVE interactor styles are now much more performant, usable, and functional.

Performance improvements

You can now run multiple interactor styles at the same time with far better performance, as all interactor styles included with ParaView (both Python and C++) have been updated to defer as much computation as possible to the Update() method, rather than doing computation in the event handling methods.

To learn about the key details of the plugin event loop that make this a sensible practice, as well as read about other best practices for writing interactor styles, see the new Incubator/CAVEInteraction/README.md.

Usability improvements

You can now more readily experiment with interactor styles, as each style has been given a "Reset" functionality. This allows you to reset the scene and any objects properties to their original values, in case you fly too far away or get turned upside down or faced away from your data.

Interactor styles have been catalogued and renamed to match their functionality. See the new Incubator/CAVEInteraction/README.md for a brief discussion of the features and corresponding nomenclature of the built-in interactor styles.

Additionally, you can now hover over each style in the combo box and see a tooltip describing the behavior and requirements of each interactor style.

Functionality improvements

You can now be more confident that interactor styles work properly, especially when used in conjunction with each other, as all interactor styles have been thoroughly tested and had bugs fixed. Many interactor styles did not properly account for the fact that other styles might already have updated the ModelTransformMatrix, and these have all been fixed.
