The 3D projection of the 2D coordinates is for this projector class constrained to lie inside a pre-defined 3D plane.
|
Constructor. Sets up a projection plane parallel with the XY-plane in world coordinates. |
|
Constructor taking an explicit projection plane definition. |
|
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. |
|
Projects 2D point into a 3D point within the current projection plane. Implements SbProjector. |
|
Set a new projection plane. |
|
Returns the current projection plane. |
|
Sets whether or not the plane should always be oriented towards the "eye" of the viewer. |
|
Returns the state of the plane orientation flag. |
|
Returns a vector between the projected 3D points of viewpos1 and viewpos2. |
|
Returns a vector between the last projected point and the projected 3D point of viewpos. |
|
Explicitly set position of initial projection, so we get correct values for later calls to getVector() etc. |

The projection plane. |
|
The "original" plane which was set (as opposed to the recalculated projection plane according to the SbPlaneProjector::orientToEye setting). |
|
Which direction the plane is oriented. |

Stores the previously projected 3D point. |
