Fields⤴
These are the X3D / X3DOM fields of this node. Values should usually be received / set as strings via
DOM functions (i.e., using
setAttribute("myFieldName", "myFieldValue") and
getAttribute("myFieldName")).
| Name | Type | Default Value | Range | Inheritance | Standard | Description |
|---|---|---|---|---|---|---|
| bind | SFBool | false | X3DBindableNode |
|
Pushes/pops the node on/from the top of the bindable stack | |
| centerOfRotation | SFVec3f | 0,0,0 |
|
The centerOfRotation field specifies a center about which to rotate the user's eyepoint when in EXAMINE mode. | ||
| description | SFString | "" | X3DBindableNode |
|
Description of the bindable node | |
| farClippingPlane | SFFloat | -1 | -1 or [0, inf] | X3DViewpointNode |
|
Specifies the far clipping plane, alias for zFar |
| fieldOfView | SFFloat | 785398 | [0, pi] |
|
Preferred minimum viewing angle from this viewpoint in radians. Small field of view roughly corresponds to a telephoto lens, large field of view roughly corresponds to a wide-angle lens. Hint: modifying Viewpoint distance to object may be better for zooming. Warning: fieldOfView may not be correct for different window sizes and aspect ratios. Interchange profile hint: this field may be ignored. | |
| isActive | SFBool | false | X3DBindableNode |
|
||
| metadata | SFNode | X3DMetadataObject | X3DNode |
|
Field to add metadata information | |
| navigationInfo | SFBool | null | X3DViewpointNode |
|
Defines a dedicated NavigationInfo node for this X3DViewpointNode. The specified NavigationInfo node receives a set_bind TRUE event at the time when the parent node is bound and receives a set_bind FALSE at the time when the parent node is unbound. | |
| nearClippingPlane | SFFloat | -1 | -1 or [0, inf] | X3DViewpointNode |
|
Specifies the near clipping plane, alias for zNear |
| orientation | SFRotation | 0,0,1,0 |
|
The orientation fields of the Viewpoint node specifies relative orientation to the default orientation. | ||
| position | SFVec3f | 0,0,10 |
|
The position fields of the Viewpoint node specifies a relative location in the local coordinate system. Position is relative to the coordinate system's origin (0,0,0), | ||
| viewAll | SFBool | false | X3DViewpointNode |
|
When the viewAll field is set to TRUE or a viewpoint is bound with viewAll field TRUE, the current view is modified to change the centerOfRotation field to match center of the bounding box for the entire visible scene, and the orientation field is modified to aim at that point. Finally, the zoom position or fieldofview is adjusted to contain the entire scene in the current viewing window. If needed, the near and far clipping planes shall be adjusted to allow viewing the entire scene. When the value of the viewAll field is changed from TRUE to FALSE, no change in the current view occurs. | |
| zFar | SFFloat | -1 | -1 or [0, inf] |
|
Specifies the far plane. | |
| zFar | SFFloat | -1 | -1 or [0, inf] |
|
Specifies the far plane. | |
| zNear | SFFloat | -1 | -1 or [0, inf] |
|
Specifies the near plane. | |
| zNear | SFFloat | -1 | -1 or [0, inf] |
|
Specifies the near plane. |
