Enum EdgeFilteringMode

java.lang.Object

java.lang.Enum<EdgeFilteringMode>

com.jme3.shadow.EdgeFilteringMode

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<EdgeFilteringMode>

public enum EdgeFilteringMode
extends java.lang.Enum<EdgeFilteringMode>

ShadowEdgeFiltering specifies how shadows are filtered

Enum Constant Summary

Enum Constants

Enum Constant and Description
Bilinear Bilinear filtering is used.
Dither Dither-based sampling is used, very cheap but can look bad at low resolutions.
Nearest Shadows are not filtered.
PCF4 4x4 percentage-closer filtering is used.
PCF8 8x8 percentage-closer filtering is used.
PCFPOISSON 12 samples percentage-closer filtering with a POISON disc distribution is used.

Enum Constant Detail

Nearest

public static final EdgeFilteringMode Nearest

Shadows are not filtered. Nearest sample is used, causing in blocky shadows.

Bilinear

public static final EdgeFilteringMode Bilinear

Bilinear filtering is used. Has the potential of being hardware accelerated on some GPUs

Dither

public static final EdgeFilteringMode Dither

Dither-based sampling is used, very cheap but can look bad at low resolutions.

PCF4

public static final EdgeFilteringMode PCF4

4x4 percentage-closer filtering is used. Shadows will be smoother at the cost of performance

PCFPOISSON

public static final EdgeFilteringMode PCFPOISSON

12 samples percentage-closer filtering with a POISON disc distribution is used. http://devmag.org.za/2009/05/03/poisson-disk-sampling/ The principle is to eliminate the regular blurring pattern that can be seen with pcf4x4 by randomizing the sample position with a poisson disc. Shadows will look smoother than 4x4 PCF but with slightly better or similar performance.

PCF8

public static final EdgeFilteringMode PCF8

8x8 percentage-closer filtering is used. Shadows will be smoother at the cost of performance

Method Detail

values

public static EdgeFilteringMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (EdgeFilteringMode c : EdgeFilteringMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static EdgeFilteringMode valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getMaterialParamValue
