SyntaxThe SoEnvironment type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SoEnvironment | Creates an environment node with default settings. |
Methods| Name | Description | |
|---|---|---|
| AffectsState | Returns true if a node has an effect on the state during traversal. |
| Callback | (Overrides SoNodeCallback(SoCallbackAction).) |
| Copy | Calls Copy(false). (Inherited from SoNode.) |
| Copy(Boolean) | Creates and returns an exact copy of the node. |
| CopyFieldValues(SoFieldContainer) | Calls CopyFieldValues(fc, false). (Inherited from SoFieldContainer.) |
| CopyFieldValues(SoFieldContainer, Boolean) | Copies the contents of fc's fields into this object's fields. |
| Dispose |
Releases all resources used by SoDisposable.
(Inherited from SoDisposable.) |
| Distribute | (Inherited from SoNode.) |
| DoAction | (Overrides SoNodeDoAction(SoAction).) |
| EnableNotify | Notification at this Field Container is enabled (if flag == true) or disabled (if flag == false). |
| Equals | (Inherited from Object.) |
| FieldsAreEqual | Returns true if this object's fields are exactly equal to fc's fields. |
| Get | Returns the values of the fields of this object in the Open Inventor ASCII file format in the given string. |
| GetAllFields | Returns a list of fields, including the eventIn's and eventOut's. |
| GetAlternateRep | This method is called by actions to allow the node to provide an "alternate representation" when appropriate (typically depending on the action type). |
| GetBoundingBox | (Inherited from SoNode.) |
| GetEventIn | Returns a the eventIn with the given name. |
| GetEventOut | Returns the eventOut with the given name. |
| GetField | Returns a the field of this object whose name is fieldName. |
| GetFieldName | Returns the name of the given field in the fieldName argument. |
| GetFields | Appends references to all of this object's fields to resultList, and returns the number of fields appended. |
| GetHashCode |
Overrides GetHashCode().
(Inherited from SoNetBase.) |
| GetMatrix | (Inherited from SoNode.) |
| GetName | Returns the name of an instance. |
| GetPrimitiveCount | (Inherited from SoNode.) |

| HasDefaultValues | Returns true if all of the object's fields have their default values. |
| IsBoundingBoxIgnoring | This method is used by getBoundingBox action traversal to know if the current node must be traversed or not, ie the bounding should be ignored. |
| IsNotifyEnabled | Notification is the process of telling interested objects that this object has changed. |
| IsOverride | Returns the state of the override field. |
| IsSynchronizable | Gets the ScaleViz synchronizable state of this object. |
| Pick | (Inherited from SoNode.) |
| RayPick | (Inherited from SoNode.) |
| Search | (Inherited from SoNode.) |
| Set | Sets one or more fields in this object to the values specified in the given string, which should be a string in the Open Inventor file format. |
| SetName | (Inherited from SoBase.) |
| SetOverride | Set the state of the override field. |
| SetSynchronizable | Sets this to be a ScaleViz synchronizable object. |
| SetToDefaults | Sets all fields in this object to their default values. |

Converts this SoBase structure to a human readable string.
(Inherited from SoBase.) |
| Touch | Marks an instance as modified, simulating a change to it. |
| Write | (Inherited from SoNode.) |
Properties| Name | Description | |
|---|---|---|
 | ambientColor | RGB color of ambient lighting (for Phong lighting). |
| ambientIntensity | Intensity of ambient lighting (for Phong lighting). |
| attenuation | Squared, linear, and constant light attenuation coefficients (in that order) with respect to distance of light from surface (for Phong lighting). |
| fogColor | Fog color. |
| fogStart | Distance at which the linear fog HAZE starts to be applied. |

| fogVisibility | Fog visibility distance, which is the distance at which fog totally obscures objects. |
| IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) |
| UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) |
RemarksThis node describes global environmental attributes such as ambient lighting, light attenuation, and fog.
Ambient lighting is the amount of extra light impinging on each surface point when the lighting model is Phong (see SoLightModel).
Light attenuation affects all subsequent lights in a scene (see SoLight). It is a quadratic function of distance from a light source to a surface point. The three coefficients are specified in the attenuation field. Attenuation works only for light sources with a fixed location, such as point and spot lights.
Fog has one of four types, each of which blends each surface point with the specified fog color. Each type interprets the fogVisibility field to be the distance at which fog totally obscures objects. A fogVisibility value of 0 (the default) causes the SoEnvironment node to set up fog so that the visibility is the distance to the far clipping plane of the current camera. Using a fog of type HAZE results in a linear fog between the fogStart value and the fogVisibility value.
Note that this node has effect only during rendering.

ACTION BEHAVIOR
SoGLRenderAction Sets the current environment parameters to those specified with this node. Successive geometries will be rendered using this environment. Sets: SoEnvironmentElement, SoLightAttenuationElement
