/**
|
|
* @brief The drawing interface
|
|
*
|
|
* A "drawing" object implements functionality to draw objects
|
|
* from a cellview onto a set of planes.
|
|
* The object can control the appearance of the planes.
|
|
* Basically, the object must implement these features:
|
|
*
|
|
* 1.) Allocate a number of planes in the constructor using
|
|
* the num_planes parameter of the "Drawing" constructor.
|
|
*
|
|
* 2.) Implement a drawing function ("paint_cv_on_planes")
|
|
* that draws the given cellview onto the planes provided.
|
|
* This method is called from the drawing thread and must not
|
|
* make use of members of the object or protect them with a
|
|
* mutex. It is also possible to implement "paint_on_planes"
|
|
* to draw without a cellview.
|
|
*
|
|
* 3.) Control the appearance of the planes planes by implementing
|
|
* the get_view_ops method.
