public class Fog
extends X3DConcreteNode
implements Fog

Fog simulates atmospheric effects by blending distant objects with fog color.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. Fog node tooltip: [X3DBindableNode,X3DFogObject] Fog simulates atmospheric effects by blending distant objects with fog color.

• Hint: Background, Fog, GeoViewpoint, NavigationInfo, OrthoViewpoint, TextureBackground and Viewpoint are bindable nodes, meaning that no more than one of each node type can be active at a given time.
• Warning: results are undefined if a bindable node (Background, Fog, NavigationInfo, OrthoViewpoint, TextureBackground, Viewpoint) is a contained descendant node of either LOD or Switch. Avoid this authoring pattern.

Note that SFColor provides a variety of color constants.

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.

Overrides:

getDEF in class X3DConcreteNode

Returns:

value of DEF field

setDEF

public final Fog setDEF(String newValue)

Accessor method to assign String value to inputOutput SFString field named DEF.

Note that setting the DEF value clears the USE value.

Specified by:

setDEF in class X3DConcreteNode

Parameters:

newValue - is new value for the DEF field.

Returns:

Fog - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

setDEF

public Fog setDEF(SFString newValue)

Assign typed object value to SFString DEF field, similar to setDEF(String).

Parameters:

newValue - is new value for the DEF field.

Returns:

Fog - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

getUSE

public String getUSE()

Provide String value from inputOutput SFString field named USE.

Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).

• Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
• Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
• Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.

Overrides:

getUSE in class X3DConcreteNode

Returns:

value of USE field

See Also:

• X3D Scene Authoring Hints: Naming Conventions

setUSE

public final Fog setUSE(String newValue)

Accessor method to assign String value to inputOutput SFString field named USE.

Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).

• Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
• Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
• Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.

Note: each USE node is still an independent object, with the USE value matching the DEF value in the preceding object.

Warning: invoking the setUSE() method on this node resets all other fields to their default values (except for containerField) and also releases all child nodes.

Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value.

Specified by:

setUSE in class X3DConcreteNode

Parameters:

newValue - is new value for the USE field.

Returns:

Fog - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
