Enum Constant Detail

NEAREST

public static final SoVolumeShape.Interpolations NEAREST

OpenGL "nearest neighbor" interpolation.

LINEAR

public static final SoVolumeShape.Interpolations LINEAR

OpenGL linear interpolation (Default). This implies bi-linear interpolation for 2D textures (e.g. SoOrthoSlice, SoObliqueSlice, SoVolumeSkin, SoFenceSlice) and tri-linear interpolation for 3D textures (SoVolumeRender, SoVolumeGeometry).

TRILINEAR

public static final SoVolumeShape.Interpolations TRILINEAR

Tri-linear interpolation for SoObliqueSlice. Tri-linear interpolation is used when extracting the 2D texture that will be applied to the slice, providing better image quality. Same as LINEAR for other nodes.

Since:

Open Inventor 6.0

MULTISAMPLE_12

public static final SoVolumeShape.Interpolations MULTISAMPLE_12

Multi-sample interpolation for slice shapes. Interpolates data values using 12 samples around the voxel. This provides much higher image quality and specifically avoids rendering artifacts due to bi-linear interpolation. Only supported for 2D texture shapes (e.g. SoOrthoSlice, SoObliqueSlice, SoVolumeSkin, SoFenceSlice). Same as LINEAR for other nodes.

Since:

Open Inventor 7.0

CUBIC

public static final SoVolumeShape.Interpolations CUBIC

Cubic interpolation. This implies bi-cubic interpolation for 2D textures (e.g. SoOrthoSlice, SoObliqueSlice, SoVolumeSkin, SoFenceSlice) and tri-cubic interpolation for 3D textures (SoVolumeRender, SoVolumeGeometry). It gives smoother results, especially for volume rendering.

Linear interpolation	Cubic interpolation

Warning Heavy GPU usage. Primarily useful for still image rendering.
It is recomended to use SoInteractiveComplexity node to switch bewteen LINEAR interpolation while moving and CUBIC interpolation for Still frame:

 SoInteractiveComplexity icplx = new SoInteractiveComplexity();
 icplx.fieldSettings.set1Value( 0, "SoVolumeRender interpolation LINEAR CUBIC" );
 root.addChild(icplx);

Since:

Open Inventor 9.3

Method Detail

values

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

Returns:

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

valueOf

public static SoVolumeShape.Interpolations 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

fromValue

@Deprecated
public static SoVolumeShape.Interpolations fromValue(int val)

Deprecated. Use valueOf(int) instead.

Returns the enum constant of this type with the specified integer value

Returns:

the enum constant of this type with the specified integer value.

valueOf

public static SoVolumeShape.Interpolations valueOf(int val)

Returns the enum constant of this type with the specified integer value

Returns:

the enum constant of this type with the specified integer value.

getValue

public int getValue()

Description copied from interface: IntegerValuedEnum

Returns the integer value of the enum constant.

Specified by:

getValue in interface IntegerValuedEnum

Returns:

the integer value of the enum constant.
