Public methodDoAction

default actions behavior

(Overrides SoNodeDoAction(SoAction).)

Notification at this Field Container is enabled (if flag == true) or disabled (if flag == false).

(Inherited from SoFieldContainer.)
Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Public methodFieldsAreEqual

Returns true if this object's fields are exactly equal to fc's fields.

(Inherited from SoFieldContainer.)
Public methodGet

Returns the values of the fields of this object in the Open Inventor ASCII file format in the given string.

(Inherited from SoFieldContainer.)
Public methodGetAllFields

Returns a list of fields, including the eventIn's and eventOut's.

(Inherited from SoFieldContainer.)
Public methodGetAlternateRep

This method is called by actions to allow the node to provide an "alternate representation" when appropriate (typically depending on the action type).

Returns a the field of this object whose name is fieldName.

(Inherited from SoFieldContainer.)
Public methodGetFieldName

Returns the name of the given field in the fieldName argument.

(Inherited from SoFieldContainer.)
Public methodGetFields

Appends references to all of this object's fields to resultList, and returns the number of fields appended.

Properties
  NameDescription
Public propertyclearBuffer

If true, the depth buffer is cleared when the node is traversed.

Public propertyfunction

Depth comparison function to use (glDepthFunc).

Public propertyIsDisposable
ISafeDisposable interface implementation.
(Inherited from SoDisposable.)
Public propertyrange

Value range for the depth buffer (glDepthRange).

Public propertytest

Enable depth buffer testing (glEnable).

Public propertyUserData
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.)
Public propertywrite

Enable depth buffer writing (glDepthMask).

Remarks

This class specifies the depth buffer parameters used for rendering, including:

  • Depth buffer test enabled,

  • Depth buffer writing enabled,

  • Depth buffer range, and

  • Depth comparison function.

It can also be used to clear the depth buffer by setting the OIV.Inventor.Nodes.SoDepthBuffer.clearBuffer field to true.

To control whether frame buffer color components are written or not, see OIV.Inventor.Nodes.SoColorMask.

Limitations:

  • Transparency: The "depth peeling" transparency types (SORTED_PIXEL) do not work correctly if this node is used to change depth buffer settings.

  • Test function By default OIV.Inventor.Nodes.SoDepthBuffer sets the OpenGL depth buffer test function to LESS. (Meaning that only fragments with a depth value strictly less than the current depth buffer value will be rendered.) This is NOT the same as the Open Inventor default. By default Open Inventor sets the depth buffer test function to LEQUAL and this value is recommended for most applications. Some Open Inventor features, for example OIV.Inventor.Nodes.SoGradientBackground, will not work correctly with the depth buffer test function set to LESS.

FILE FORMAT/DEFAULT

DepthBuffer {
test true
write true
function LESS
range (0.0,1.0)
clearBuffer false
}
