Class ParametricSurfaceFactory.DefaultImmersion

java.lang.Object

de.jreality.geometry.ParametricSurfaceFactory.DefaultImmersion

All Implemented Interfaces:

ParametricSurfaceFactory.Immersion

Enclosing class:

ParametricSurfaceFactory

public abstract static class ParametricSurfaceFactory.DefaultImmersion
extends Object
implements ParametricSurfaceFactory.Immersion

An abstract implementation of the interface Immersion for a map of two variables into 3-space. Override the abstract method evaluate and assign the protected variables x, y, and z there depending on the given u, v values.

Modifier and Type	Method and Description
abstract void	evaluate(double u, double v) Assign the protected variables x, y, z here.
void	evaluate(double u, double v, double[] xyz, int index) The implementation of the formula.
int	getDimensionOfAmbientSpace() The dimension of the target space.
boolean	isImmutable() Mutable immersions are always recalculated when the update method is called; immutable immersions are only recalculated when the parameter domain changes.

Method Detail

isImmutable

public boolean isImmutable()

Description copied from interface: ParametricSurfaceFactory.Immersion

Mutable immersions are always recalculated when the update method is called; immutable immersions are only recalculated when the parameter domain changes.

Specified by:

isImmutable in interface ParametricSurfaceFactory.Immersion

getDimensionOfAmbientSpace

public int getDimensionOfAmbientSpace()

Description copied from interface: ParametricSurfaceFactory.Immersion

The dimension of the target space.

Specified by:

getDimensionOfAmbientSpace in interface ParametricSurfaceFactory.Immersion

evaluate

public void evaluate(double u,
                     double v,
                     double[] xyz,
                     int index)

Description copied from interface: ParametricSurfaceFactory.Immersion

The implementation of the formula. If in mathematical notation (f1(u,v), ..., fn(u,v)) is your Rⁿ valued map, where n is the dimension of the ambient space. Then your implementation of evaluate should read

                xyz[3*index]=f1(u,v);
                xyz[3*index+1]=f2(u,v);
                   ...
                xyz[3*index+n-1]=fn(u,v);
  

Specified by:

evaluate in interface ParametricSurfaceFactory.Immersion

Parameters:

u - coordinate of the requested value

v - coordinate of the requested value

xyz - an array to put the result of the evaluation into

index - at which to put the result into xyz.

evaluate

public abstract void evaluate(double u,
                              double v)

Assign the protected variables x, y, z here.

Parameters:

u -

v -
