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.
|
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. |
|
Constructor with explicit setting of the projection cylinder. |
|
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. |
|
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. Implements SbCylinderProjector. Reimplemented in SbCylinderPlaneProjector. |
|
Returns rotation on the projection surface which re-orients point1 to point2. Implements SbCylinderProjector. Reimplemented in SbCylinderPlaneProjector. |
|
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. |
|
Returns edge tolerance for the cylinder half. |
|
Check if point is within the part of the cylinder used for projections. |
|
Recalculate the internal projection surface settings. Needs to be done if any of the parameters influencing the projection surface have been changed from subclasses without using the access methods. |
|
Tolerance value, deciding how much of the half-cylinder to do projections against. |
|
Tolerance value multiplied with the cylinder radius. |
|
Direction of cutting plane. |
|
A line within the plane which is parallel to the cylinder axis. |
|
Distance from plane to cylinder axis. |
|
Defines the plane cutting the cylinder into a projection part. |
