* Fix faulty log category and minor inconsistencies in GlobeTranslation and GlobeRotation * Small refactor * Remove unused return value from initialize function * Fill attached node in globetranslation initialize and initialize all timeline Should make the timeline translation work with globetranslations in other cases that the renderabletrails * Do the same type of change for rotation and scale * Update initialize function singatures * Initialize and update translation in trail before use * Screenspace renderable renderable - move initialize call to initialize * Refactor trail position calls to make it clearer what is being done * Call timeframe initialize functions in transform classes * Do not call update in trail position after all - it borks up the performance * GlobeTransform: Only fill attached node in init and onchange, and allow nodes without renderable * Correctly initialize the multi-transform types * Apply suggestions from code review * Apply suggestions from code review Co-authored-by: Alexander Bock <alexander.bock@liu.se> * Address code review comment * Update comments in renderabletrail --------- Co-authored-by: Alexander Bock <alexander.bock@liu.se>

/**
|
|
* This class represents a configurable rotation which may or may not be time-dependent.
|
|
* Generally, classes of this type should be created through the #createFromDictionary
|
|
* function, which takes a dictionary that describes the type of Rotation to create and
|
|
* the parameters for the specific type that should be created.
|
|
*
|
|
* For general use-case by the wider system, the Rotation class should get at most one
|
|
* call to the #update method, which call calculate the Rotation using the provided data
|
|
* and cache the results, making subsequent calls to matrix() very efficient. For more
|
|
* advanced use cases, the matrix(const UpdateDate&) function will calulcate the rotation
|
|
* every time it is called.
|
|
*
|
|
* Generally, when implementing a new type of this class, only the
|
|
* matrix(const UpdateDate&) verison needs to be implemented as this base class will
|
|
* handle the caching.
