Detailed Description

Node that controls full-scene antialiasing.

This class controls full-scene antialiasing. This node can be used to enable or disable the antialiasing mode on a part of a scene graph.

This node has no effect if full-scene antialiasing is not supported in the graphics hardware or has not been enabled. Full-scene antialiasing can be enabled by defining a graphic configuration template, by calling the setAntialiasing() method in SoSceneManager and some viewer classes, or (on some systems) by the user through the system display properties dialog.

The filter field allows you to select what kind of nodes (derived from SoShape) will be antialiased. For certain primitives antialiasing may be undesirable. For example, bitmap text (SoText2, etc.) may be "blurred" by antialiasing.

The filter result is highly dependent on your graphics hardware.

Note: The quality level specified by the setAntialiasing() method cannot be changed during a traversal because it depends on the pixel format.

Member Enumeration Documentation

enum SoFullSceneAntialiasing::Filter

Defines the types of rendering shapes.

Enumerator:

POINTS	The shape is render based on points (Ex: SoPointSet).
LINES	The shape is render based on lines (Ex: SoLineSet).
POLYGONS	The shape is render based on polygons (Ex: SoFaceSet).
TEXT	The shape is a text and follows the special filter for texts.
ALL	No specific filter for antialiasing (Default).

Member Data Documentation

SoSFBitMask SoFullSceneAntialiasing::filter

A bit-wise combination of LINES, POINTS, POLYGONS, and TEXT that determines which primitive types should be antialiased.

Default = ALL. The default value can be set using the environment variable OIV_FULL_SCENE_ANTIALIASING_FILTER. Valid values are ALL, or any combination of LINES, POINTS, POLYGONS, and TEXT.

The rules to determine if the antialiasing extension should stay enabled or should be disabled are described in the following tables:

Shape Type Draw Style Filter Enable AA POLYGON FILLED LINES POINTS POLYGONS TEXT ALL X X LINES LINES POINTS POLYGONS TEXT ALL X X POINTS LINES POINTS POLYGONS TEXT ALL X X INVISIBLE -	Shape Type Draw Style Filter Enable AA TEXT FILLED LINES POINTS POLYGONS TEXT ALL X X X LINES LINES POINTS POLYGONS TEXT ALL X X X POINTS LINES POINTS POLYGONS TEXT ALL X X X INVISIBLE -   All text are antialiased when the SoFullSceneAntialiasing filter is set to TEXT Otherwise, the AA is made considering the draw style element state.
Shape Type Draw Style Filter Enable AA LINE FILLED LINES LINES POINTS POLYGONS TEXT ALL X X POINTS LINES POINTS POLYGONS TEXT ALL X X INVISIBLE -	Shape Type Draw Style Filter Enable AA POINT FILLED LINES POINTS LINES POINTS POLYGONS TEXT ALL X X INVISIBLE -

 

SoSFBool SoFullSceneAntialiasing::on

Enables/disables full-scene antialiasing.

Default = TRUE. The default value can be set using the environment variable OIV_FULL_SCENE_ANTIALIASING (0 = FALSE, 1 = TRUE).
