Detailed Description

The SbCylinderPlaneProjector class projects 2D points to a half-cylinder and a plane.

This projector uses a plane along with the half-cylinder of SbCylinderSectionProjector for projections. If the 2D point mapping "misses" the cylinder section, the 3D point will be projected onto the plane.

Constructor & Destructor Documentation

SbCylinderPlaneProjector::SbCylinderPlaneProjector const float    edgetol = 0.9f,
const SbBool    orienttoeye = TRUE
 

Default constructor. See SbCylinderSectionProjector::SbCylinderSectionProjector().

SbCylinderPlaneProjector::SbCylinderPlaneProjector const SbCylinder   cyl,
const float    edgetol = 0.9f,
const SbBool    orienttoeye = TRUE
 

Constructor with explicit specification of projection cylinder.


Member Function Documentation

SbProjector * SbCylinderPlaneProjector::copy void    const [virtual]
 

Construct and return a copy of this projector. The caller is responsible for destructing the new instance.

Note that if the Coin library has been built as a DLL under Microsoft Windows and you use this method from application code, you must make sure that both the Coin DLL and the application executable is using the same instance of a C Run-Time (CRT) library. Otherwise, you will get memory heap corruption upon deallocating the returned instances, eventually leading to mysterious crashes.

Reimplemented from SbCylinderSectionProjector.

SbVec3f SbCylinderPlaneProjector::project const SbVec2f   point [virtual]
 

Project the 2D point from normalized viewport coordinates to a 3D point. The mapping will be done in accordance with the type of the projector.

Reimplemented from SbCylinderSectionProjector.

SbRotation SbCylinderPlaneProjector::getRotation const SbVec3f   point1,
const SbVec3f   point2
[virtual]
 

Returns rotation on the projection surface which re-orients point1 to point2.

Reimplemented from SbCylinderSectionProjector.

SbRotation SbCylinderPlaneProjector::getRotation const SbVec3f   point1,
const SbBool    tol1,
const SbVec3f   point2,
const SbBool    tol2
[protected]
 

Calculates rotation from point1 to point2, with tol1 and tol2 deciding whether or not to use the tolerance setting.
