Detailed Description
Common algorithms for all viewers.
This class provides common viewer algorithms in order to more easily create a viewer class from scratch. The algorithms provided deal with animations, camera management, etc. This class regroups algorithms from all the viewer types (examiner, plane, fly and walk).
There are two ways to use this class:
1) Passed as an argument to the RenderArea.
SoGuiAlgoViewers* pAlgo = new SoGuiAlgoViewers(); SoXXRenderArea( parent, name, buildInsideParent, getMouseInput, getKeyboardInput, pAlgo );
2) Use your own GL widget and call the necessary functions for the interactions and the rendering.
See the demo QtViewer for more information.
There are two projection modes for the "virtual trackball" that translates mouse motion into camera rotation:
- SPHERICAL: Spherical rotation (the classic Open Inventor algorithm).
Uses an SbSphereSheetProjector to determine rotation angle and rotation axis used to rotate the camera. - CYLINDRICAL: Cylindrical rotation.
Uses an SbCylinderSheetProjector. The axis is the direction normal to the movement of the cursor on the screen and the angle is proportional to the mouse movement. The coefficient can be set using the setMouseAngularSpeed() method.
The viewer can use two zooming modes:
- AUTOCENTER: The legacy algorithm that zooms around the viewport center.
- GIVENPOINT: Uses as the zooming center a point provided by the application through the setCurrentMousePositionLocator() method before calling mouseWheelMotion().

By default an SoPerspectiveCamera will be created if no cameras are found.
Note: The set method will only take effect the next time a scene graph is specified (and if no cameras are found). Moreover with fly or walk viewers orthographic cameras don't make sense and are not supported.
Reimplemented from SoGuiViewer.
| void SoGuiAlgoViewers::setConstrained | ( | SbBool | constrained | ) |
Specifies whether algorithms for constrained viewers should be used.
| void SoGuiAlgoViewers::setCurrentMousePositionLocator | ( | const SbVec2s & | mousePosition | ) |
Sets the current mouse position.
- Parameters:
-
mousePosition The new mouse position in pixels. The coordinates must be defined with x in the range [0,window width] and y in the range [0,window height] with min y at the bottom and min x on the left.
| void SoGuiAlgoViewers::setCurrentSpeed | ( | float | speed | ) |
Sets the current speed.
Sets the current drawing style in the main view.
The user can specify the INTERACTIVE draw style (draw style used when the scene changes) independently from the STILL style. Default is VIEW_AS_IS draw style for STILL and VIEW_SAME_AS_STILL for INTERACTIVE.
The default value can be set using the environment variables OIV_STILL_DRAW_STYLE and OIV_INTERACTIVE_DRAW_STYLE. Valid values are VIEW_AS_IS, VIEW_HIDDEN_LINE, VIEW_NO_TEXTURE, VIEW_LOW_COMPLEXITY, VIEW_LINE, VIEW_POINT, VIEW_BBOX, VIEW_LOW_RES_LINE, VIEW_LOW_RES_POINT for OIV_STILL_DRAW_STYLE and the same plus VIEW_SAME_AS_STILL for OIV_INTERACTIVE_DRAW_STYLE.
Possible draw styles are: VIEW_AS_IS - Leaves the objects unchanged.
VIEW_HIDDEN_LINE - Renders the object as wireframe, but only shows the object front faces. This is accomplished using a two-pass rendering. In the first pass, the objects are rendered as FILLED using the background BASE_COLOR (this sets up the wanted z-buffer values). The second pass then renders the objects as LINES, while adjusting the z-buffer range to limit overlapping polygons problems.
VIEW_NO_TEXTURE - Renders the objects without any textures. This is done by setting the override flag on an empty SoTexture2 node.
VIEW_LOW_COMPLEXITY - Renders the objects without any textures and with a low complexity. This is done by setting the override flag on an empty SoTexture2 node, and by setting a low complexity value on an SoComplexity node with override set to TRUE.
VIEW_LINE - Renders the objects as LINES (no texture) with lighting model set to BASE_COLOR.
VIEW_LOW_RES_LINE - Renders the objects as LINES (no texture) using a low complexity, with lighting model set to BASE_COLOR and no depth comparison.
VIEW_POINT - Renders the objects as POINTS (no texture) with lighting model set to BASE_COLOR.
VIEW_LOW_RES_POINT - Renders the objects as POINTS (no texture) using a low complexity, with lighting model set to BASE_COLOR and no depth comparison.
VIEW_BBOX - Renders the objects with complexity BOUNDING_BOX, lighting model set to BASE_COLOR and drawing style LINES (no texture) with no depth comparison.
VIEW_SAME_AS_STILL - This only applies to INTERACTIVE draw type. It enables the interactive draw style mode to match the regular draw style mode without having to set it explicitly.
| virtual void SoGuiAlgoViewers::setHeadlight | ( | SbBool | insertFlag | ) | [virtual] |
Turns the headlight on/off (default on).
The default value can be set using the environment variable OIV_USE_HEADLIGHT (0 = FALSE, 1 = TRUE).

Default is 1.
| virtual void SoGuiAlgoViewers::setMPEGRecorder | ( | SoMPEGRenderer * | recorder | ) | [virtual] |

- Parameters:
-
recorder the recorder to be used.
Note: The destruction of the recorder is handled by SoGuiAlgoViewers.
Reimplemented from SoGuiRenderArea.

For instance: setPlane( SbVec3f(1, 0, 0), SbVec3f(0, 0, -1) ) will align the camera with the X plane.
| virtual void SoGuiAlgoViewers::setPreserveCameraHeightAngle | ( | SbBool | flag | ) | [virtual] |

Default is FALSE.
Reimplemented from SoGuiViewer.
| void SoGuiAlgoViewers::setPrevAnimTime | ( | SbTime | previous | ) |
Sets the previous animation time.
| void SoGuiAlgoViewers::setPreviousMousePositionLocator | ( | const SbVec2s & | mousePosition | ) |
Sets the previous mouse position.
- Parameters:
-
mousePosition The new mouse position in pixels. The coordinates must be defined with x in the range [0,window width] and y in the range [0,window height] with min y at the bottom and min x on the left.
| virtual void SoGuiAlgoViewers::setRotationTargetPosition | ( | const SbVec3f & | targetPos | ) | [virtual] |
Sets the camera target position for rotations.
| virtual void SoGuiAlgoViewers::setSceneGraph | ( | SoNode * | newScene | ) | [virtual] |
Sets the scene graph to render.
Whenever a new scene is supplied the first camera encountered will be by default used as the edited camera, else a new camera will be created. If the scene graph does not contain any light nodes, the viewer inserts a headlight (directional light which is made to follow the camera) immediately after the camera. See the main description of this class for further details.
Reimplemented from SoGuiViewer.
| virtual void SoGuiAlgoViewers::setSeekMode | ( | SbBool | onOrOff | ) | [virtual] |
Set the viewer into/out of seek mode (default OFF).
Actual seeking will not happen until the viewer decides to, for example, on a mouse click.
Note: Setting the viewer out of seek mode while the camera is being animated will stop the animation at the current location.
Reimplemented from SoGuiViewer.
| void SoGuiAlgoViewers::setSheetProjectionType | ( | const ProjectorsType & | projType | ) |
Specifies the sheet projection to use for rotations.
Use enum ProjectorsType. Default is SPHERICAL.
| void SoGuiAlgoViewers::setSpeedLimit | ( | float | limit | ) |
Sets the speed limit.
| void SoGuiAlgoViewers::setStartMousePositionLocator | ( | const SbVec2s & | mousePosition | ) |

- Parameters:
-
mousePosition The new mouse position in pixels. The coordinates must be defined with x in the range [0,window width] and y in the range [0,window height] with min y at the bottom and min x on the left.
| void SoGuiAlgoViewers::setViewerType | ( | ViewerTypes | vType | ) |
Sets the type of viewer used for the algorithms.
| virtual void SoGuiAlgoViewers::setViewing | ( | SbBool | flag | ) | [virtual] |
Sets whether the viewer is turned on or off.
When turned on (commonly called viewing mode), events are consumed by the viewer. When viewing is off (commonly called selection mode), events are processed by the viewer's render area. This means events will be sent down to the scene graph for processing (i.e. picking can occur). Note that if the application has registered an event callback, it will be invoked on every message, whether viewing is turned on or not. However, the return value of this callback (which specifies whether the callback handled the event or not) is ignored when viewing is on. That is, the viewer will process the event even if the callback already did. This is to ensure that the viewing paradigm is not broken (default viewing is on).
Reimplemented from SoGuiViewer.
