Enum Constant Summary

Enum Constants

Enum Constant	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.

Method Summary

Modifier and Type	Method	Description
int	getValue()	Returns the integer value of the enum constant.
static SoVolumeRender.SamplingAlignments	valueOf(int val)	Returns the enum constant of this type with the specified integer value
static SoVolumeRender.SamplingAlignments	valueOf(String name)	Returns the enum constant of this class with the specified name.
static SoVolumeRender.SamplingAlignments[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

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
