Enum Constant Summary

Enum Constants

Enum Constant and Description
Cubic Values are set by cubic Catmull interpolation between the surrounding knot points.
CubicStep Values are set by cubic hermite interpolation between the surrounding knot points.
Linear Values are set by linear interpolation of the closest surrounding knot points.
Parabolic Values are set by quadartic interpolation of the surrounding knot points.
SphericalCubic Where appropriate, 3D rotation values are set by spherical cubic interpolation (i.e., "slerp", as described by Shoemake's 1985 SIGGRAPH paper).
SphericalLinear Where appropriate, 3D rotation values are set by piecewise spherical linear interpolation (i.e., "slerp", as described by Shoemake's 1985 SIGGRAPH paper).
Step Values are set to the values of the closest previous knots points.

Enum Constant Detail

Step

public static final Interpolation.Order Step

Values are set to the values of the closest previous knots points.

Linear

public static final Interpolation.Order Linear

Values are set by linear interpolation of the closest surrounding knot points.

Parabolic

public static final Interpolation.Order Parabolic

Values are set by quadartic interpolation of the surrounding knot points.

Cubic

public static final Interpolation.Order Cubic

Values are set by cubic Catmull interpolation between the surrounding knot points.

CubicStep

public static final Interpolation.Order CubicStep

Values are set by cubic hermite interpolation between the surrounding knot points. Slopes are set to zero.

SphericalLinear

public static final Interpolation.Order SphericalLinear

Where appropriate, 3D rotation values are set by piecewise spherical linear interpolation (i.e., "slerp", as described by Shoemake's 1985 SIGGRAPH paper). Otherwise, interpolation is linear.

SphericalCubic

public static final Interpolation.Order SphericalCubic

Where appropriate, 3D rotation values are set by spherical cubic interpolation (i.e., "slerp", as described by Shoemake's 1985 SIGGRAPH paper). Otherwise, interpolation is cubic.

Method Detail

values

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

Returns:

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

valueOf

public static Interpolation.Order 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

fromString

public static Interpolation.Order fromString(java.lang.String str)
