Method Detail

compute

boolean compute(double u,
                double v)

Compute the interpolation / approximation (front-end only).

Parameters:

u - U parameter.

v - V parameter.

Returns:

true if this service is implemented.

interpolate

double interpolate(double u,
                   double v)

Compute scalar interpolation / approximation.

Parameters:

u - U parameter.

v - V parameter.

Returns:

Interpolated value.

interpolate

boolean interpolate(double u,
                    double v,
                    double[] res)

Compute vector interpolation / approximation.

Parameters:

u - U parameter.

v - V parameter.

res - Pre-allocated result array.

Returns:

true if this service is implemented.

getDomain

boolean getDomain(double[] dom)

Returns domain of the [U,V] parameters.

Parameters:

dom - Domain array (dom[0] = Umin, dom[1] = Umax, dom[2] = Vmin, dom[3] = Vmax).

Returns:

true if this service is implemented.

setDomain

boolean setDomain(double[] dom)

Sets domain of the [U,V] parameters.

Parameters:

dom - Domain array (dom[0] = Umin, dom[1] = Umax, dom[2] = Vmin, dom[3] = Vmax).

Returns:

true if this service is implemented.

setAttribute

boolean setAttribute(double u,
                     double v,
                     double[] attr)

Sets a knot attribute (whatever it is) for value of [U,V].

Parameters:

u - U parameter.

v - V parameter.

attr - Attribute array (semanthics is not defined).

Returns:

true if this service is implemented.
