 \- The projector classes are used to convert between screenspace (2D) locations and locations in worldspace (3D).

## SYNOPSIS

### Classes

class **SbCylinderPlaneProjector**\
 The **SbCylinderPlaneProjector** class projects 2D points to a half-cylinder and a plane.  class **SbCylinderProjector**\
 The **SbCylinderProjector** class is the abstract base class for mapping to cylindrical surfaces.  class **SbCylinderSectionProjector**\
 The **SbCylinderSectionProjector** projects 2D points to a sliced cylinder.  class **SbCylinderSheetProjector**\
 The **SbCylinderSheetProjector** class projects 2D points to 3D points on a sheet covering a cylindrical shape.  class **SbLineProjector**\
 The **SbLineProjector** class projects 2D points to 3D points along a line.  class **SbPlaneProjector**\
 The **SbPlaneProjector** class projects 2D points to 3D points in a plane.  class **SbProjector**\
 The **SbProjector** class is the abstract base projector class.  class **SbSpherePlaneProjector**\
 The **SbSpherePlaneProjector** class projects 2D points to a half-sphere and a plane.  class **SbSphereProjector**\
 The **SbSphereProjector** class is the abstract base class for mapping to spherical surfaces.  class **SbSphereSectionProjector**\
 The **SbSphereSectionProjector** projects 2D points to a sliced sphere.  class **SbSphereSheetProjector**\
 The **SbSphereSheetProjector** class projects 2D points to 3D points on a sheet covering a spherical shape.

## Detailed Description

The projector classes are used to convert between screenspace (2D) locations and locations in worldspace (3D).

They are mostly used in relation to user interaction with the mouse in the viewport.
