sbcylinderplaneprojector(3)
NAME
SbCylinderPlaneProjector
SYNOPSIS
#include <Inventor/projectors/SbCylinderPlaneProjector.h> Inherits SbCylinderSectionProjector.
Detailed Description
The SbCylinderPlaneProjector class projects 2D points to a halfcylinder 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.

Default constructor. See
SbCylinderSectionProjector::SbCylinderSectionProjector(). - Referenced by copy().

- const float edgetol = 0.9f, const SbBool orienttoeye = 1) 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.

- 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.

Calculates rotation from point1 to point2, with tol1 and tol2 deciding whether or not to use the tolerance setting. - References SbVec3f::cross(), SbCylinderProjector::cylinder,
