Enum Constant Summary

Enum Constants

Enum Constant and Description
BOUNDARY_ALIGNED Samples are located on shells aligned with the volume's internal "boundary".
DATA_ALIGNED Samples are located on planes perpendicular to one axis of the volume.
SMOOTH_BOUNDARY_ALIGNED Similar to BOUNDARY_ALIGNED but uses a cubic interpolation to compute the boundary, giving smoother results when using SoVolumeRenderingQuality.deferredLighting.
VIEW_ALIGNED Samples are located on planes perpendicular to the view direction.

Enum Constant Detail

VIEW_ALIGNED

public static final SoVolumeRender.SamplingAlignments VIEW_ALIGNED

Samples are located on planes perpendicular to the view direction.

DATA_ALIGNED

public static final SoVolumeRender.SamplingAlignments DATA_ALIGNED

Samples are located on planes perpendicular to one axis of the volume.

BOUNDARY_ALIGNED

public static final SoVolumeRender.SamplingAlignments BOUNDARY_ALIGNED

Samples are located on shells aligned with the volume's internal "boundary". Each ray begins sampling at the first intersected voxel that has an alpha value > opacityThreshold.

SMOOTH_BOUNDARY_ALIGNED

public static final SoVolumeRender.SamplingAlignments SMOOTH_BOUNDARY_ALIGNED

Similar to BOUNDARY_ALIGNED but uses a cubic interpolation to compute the boundary, giving smoother results when using SoVolumeRenderingQuality.deferredLighting. When using linear interpolation and deferred lighting, BOUNDARY_ALIGNED can generate "flat shading" due to linear interpolation between voxels. SMOOTH_BOUNDARY_ALIGNED will generate a smooth shading using a cubic interpolation to find the volume's boundary and use a linear interpolation for the rest of volume. This is a good compromise between result and performances of a full tricubic interpolation. Please refer to SoVolumeRenderingQuality.deferredLighting and SoVolumeShape.interpolation for details. LIMITATIONS SMOOTH_BOUNDARY_ALIGNED is not supported in the following case:

• With isosurface rendering
• When using gradients computed from the voxel values (SoVolumeRenderingQuality.lighting for instance).
• When using SoUniformGridClipping nodes. In one of the above case, BOUNDARY_ALIGNED is used.

  Warning Possibly heavy GPU usage

Method Detail

values

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

Returns:

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

valueOf

public static SoVolumeRender.SamplingAlignments 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 SoVolumeRender.SamplingAlignments 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 SoVolumeRender.SamplingAlignments 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.
