Interface Selectable
- All Known Implementing Classes:
- SelectableScatter, SelectableSphere, TexturedCube, TexturedCylinder
public interface Selectable
An Selectable object is supposed to be able to compute its projection
on the screen according to the Camera settings (viewport, viewpoint, etc).
The View provides a mean to update the projection of all Selectable
held by the scene's Graph. Indeed, interaction sources such as an
AbstractMouseSelector are supposed to call view.project()
to query an update of all Selectable objects' projections.
Projection implementation is rather fast but one should consider projecting only
when required, i.e. when the actual scene's Graph projection changes, which is:
- when view point changes
- when view scaling changes
- when the objects data (shape) changes
So the user is responsible of handling appropriate calls to view.project()
