Member Function Documentation
◆ cosMaxFieldAngle()
|
overridevirtual |
This function returns the cosine of the maximum field angle, i.e., the maximum angular distance from the focus for which a point should be projected.
Default is 0, i.e., 90 degrees.
Reimplemented from Projector.
Definition at line 35 of file stereographicprojector.cpp.
◆ projectionK()
|
overridevirtual |
This function handles some of the projection-specific code.
- See also
- toScreen()
Reimplemented from Projector.
Definition at line 25 of file stereographicprojector.cpp.
◆ projectionL()
|
overridevirtual |
This function handles some of the projection-specific code.
- See also
- toScreen()
Reimplemented from Projector.
Definition at line 30 of file stereographicprojector.cpp.
◆ radius()
|
overridevirtual |
Get the radius of this projection's sky circle.
- Returns
- the radius in radians
Reimplemented from Projector.
Definition at line 19 of file stereographicprojector.cpp.
◆ type()
|
overridevirtual |
Return the type of this projection.
Implements Projector.
