Enum Constant Detail

SMOOTH

public static final SoBaseExtrusion.ExtrusionModes SMOOTH

Default extrusion algorithm. The algorithm uses constant section parts cut at spine points in a way similar to what a framer would do to build a frame. This provides a better continuity of the shape and avoids cracks.

This algorithm determines the piecewise extrusion directions as a vector between consecutive spine points. This means that zero or really small distances between consecutive points can produce odd extrusion directions and result in wrong geometry. It is up to the application to filter spine points to avoid these cases. The algorithm can produce odd geometries when spines points are overlapping or zigzags.

BASIC

public static final SoBaseExtrusion.ExtrusionModes BASIC

Old extrusion algorithm. It does not guarantee that extrusion portions have constant section and shapes could be more twisted.

SMOOTH_WITHOUT_SELF_INTERSECTIONS

public static final SoBaseExtrusion.ExtrusionModes SMOOTH_WITHOUT_SELF_INTERSECTIONS

Smooth but avoids self intersections caused by large curvature radius of the spine. When the spine has curves with a large curvature radius compared to the radius of the extrusion section, SMOOTH generation might produce self intersections. Use this mode to avoid self intersections at the cost of some localized violation of the extrusion smoothness. (Section parts at spine joints may not be constant where self intersections were present.) This mode is useful to avoid artifacts in boolean results when SoBaseExtrusion derived objects are used as operands for CSG operations.

Method Detail

values

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

Returns:

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

valueOf

public static SoBaseExtrusion.ExtrusionModes 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

valueOf

public static SoBaseExtrusion.ExtrusionModes 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.
