Enum Constant Detail

POINT

public static final TextureMinFilter POINT

Selects the nearest texel in the level 0 texture map.

Uses the value of the texture element that is nearest (in Manhattan distance) to the center of the pixel being textured.

BILINEAR

public static final TextureMinFilter BILINEAR

Performs a bilinear interpolation on the four nearest texels in the level 0 texture map.

Uses the weighted average of the four texture elements that are closest to the center of the pixel being textured. These can include border texture elements, depending on the values of GL_TEXTURE_WRAP_S and GL_TEXTURE_WRAP_T, and on the exact mapping.

TRILINEAR

public static final TextureMinFilter TRILINEAR

Performs a trilinear interpolation of the texels between four texels each from the two nearest mipmap levels.

Chooses the two mipmaps that most closely match the size of the pixel being textured and uses the BASE_LEVEL_LINEAR criterion (a weighted average of the four texture elements that are closest to the center of the pixel) to produce a texture value from each mipmap. The final texture value is a weighted average of those two values.

Falls back to BILINEAR, if mipmapping is not used!

ANISOTROPIC_2

public static final TextureMinFilter ANISOTROPIC_2

Uses TRILINEAR as base filter and additionally applies a 2x anisotropic filter, if available.

Falls back to TRILINEAR only, if not available.

ANISOTROPIC_4

public static final TextureMinFilter ANISOTROPIC_4

Uses TRILINEAR as base filter and additionally applies a 4x anisotropic filter, if available.

Falls back to ANISOTROPIC_2, if 4x is not available and to TRILINEAR only, if no anisotropic filter is available.

ANISOTROPIC_8

public static final TextureMinFilter ANISOTROPIC_8

Uses TRILINEAR as base filter and additionally applies an 8x anisotropic filter, if available.

Falls back to lower anisotropics, if 8x is not available and to TRILINEAR only, if no anisotropic filter is available.

ANISOTROPIC_16

public static final TextureMinFilter ANISOTROPIC_16

Uses TRILINEAR as base filter and additionally applies a 16x anisotropic filter, if available.

Falls back to lower anisotropics, if 16x is not available and to TRILINEAR only, if no anisotropic filter is available.

Field Detail

FASTEST

public static final TextureMinFilter FASTEST

Method Detail

values

public static TextureMinFilter[] 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 (TextureMinFilter c : TextureMinFilter.values())
    System.out.println(c);

Returns:

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

valueOf

public static TextureMinFilter 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

getOpenGLBaseFilter

public final int getOpenGLBaseFilter(boolean mipmapping)

getAnisotropicLevel

public final int getAnisotropicLevel()
