Detailed Description

The SbCylinderSectionProjector projects 2D points to a sliced cylinder.

The projection cylinder for this class is sliced by a clipping plane parallel to its height axis. Projections will be mapped to the remaining cylinder part.

Constructor & Destructor Documentation

◆ SbCylinderSectionProjector() [1/2]

SbCylinderSectionProjector::SbCylinderSectionProjector ( const float  edgetol = 0.9f,
const SbBool  orienttoeye = 1 
)

Default constructor. See SbCylinderProjector::SbCylinderProjector().

The edgetol value should be within <0, 1], and specifies how much of the cylinder is used as a projection surface. 1.0 means the full front half is used.

References SbCylinderProjector::needSetup.

Referenced by copy().

◆ SbCylinderSectionProjector() [2/2]

SbCylinderSectionProjector::SbCylinderSectionProjector ( const SbCylinder cyl,
const float  edgetol = 0.9f,
const SbBool  orienttoeye = 1 
)

Constructor with explicit setting of the projection cylinder.

References SbCylinderProjector::needSetup.

Member Function Documentation

◆ copy()

SbProjector * SbCylinderSectionProjector::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.

Implements SbProjector.

Reimplemented in SbCylinderPlaneProjector.

References SbCylinderSectionProjector().

◆ project()

SbVec3f SbCylinderSectionProjector::project ( const SbVec2f point)
virtual

◆ getRotation()

SbRotation SbCylinderSectionProjector::getRotation ( const SbVec3f point1,
const SbVec3f point2 
)
virtual

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

Implements SbCylinderProjector.

Reimplemented in SbCylinderPlaneProjector.

References SbCylinderProjector::cylinder, SbVec3f::dot(), SbCylinder::getAxis(), SbLine::getClosestPoint(), SbLine::getDirection(), and SbRotation::getValue().

Referenced by SbCylinderPlaneProjector::getRotation().

◆ setTolerance()

void SbCylinderSectionProjector::setTolerance ( const float  edgetol)

The edgetol value decides how much of the surface of the cylinder is used for projection. 1.0 means the full cylinder half is used.

References SbCylinderProjector::needSetup, SoDebugError::postWarning(), and tolerance.

◆ getTolerance()

float SbCylinderSectionProjector::getTolerance ( void  ) const

Returns edge tolerance for the cylinder half.

References tolerance.

◆ isWithinTolerance()

SbBool SbCylinderSectionProjector::isWithinTolerance ( const SbVec3f point)

◆ setupTolerance()

void SbCylinderSectionProjector::setupTolerance ( void  )
protectedvirtual

◆ tolDist

SbCylinderSectionProjector::tolDist
protected

Tolerance value multiplied with the cylinder radius.

protected

Direction of cutting plane.

◆ planeLine

SbCylinderSectionProjector::planeLine
protected

A line within the plane which is parallel to the cylinder axis.

Referenced by SbCylinderPlaneProjector::getRotation(), isWithinTolerance(), project(), and setupTolerance().

◆ planeDist

SbCylinderSectionProjector::planeDist
protected

Distance from plane to cylinder axis.

Referenced by setupTolerance().
