public class SoAccumulationAntialiasingParameters extends SoAntialiasingParameters
Antialiasing parameters class for the accumulation buffer algorithm. This class provides the different parameters that can be set to configure the accumulation buffer antialiasing algorithm. These objects are used with the setAntialiasing() method inSoSceneManager
and some viewer classes (e.g.SoWinGLWidget
).There are actually two kinds of antialiasing available: smoothing and multipass antialiasing. If smoothing is set to true, smoothing is enabled. Smoothing uses OpenGL's line- and point-smoothing features to provide cheap antialiasing of lines and points. Line smoothing is an inexpensive solution for wire frame geometry. The value of numPasses controls multipass antialiasing. Each time a render action is applied, Open Inventor renders the scene numPasses times from slightly different camera positions, averaging the results. numPasses can be from one to 255, inclusive. Setting numPasses to one disables multipass antialiasing. You can use either, both, or neither of these antialiasing techniques. By default, both smoothing and multipass antialiasing are disabled.
Increasing the number of render passes can significantly reduce performance for large scenes. As a result this technique has generally been replaced by FSAA and FXAA techniques.
