Implements a three-dimensional simplex scalar noise field.

Constructors

SimplexScalarField

#
public SimplexScalarField()
Create a default three dimensional simplex field.

SimplexScalarField

#
public SimplexScalarField(double minimum, double maximum, double wavelength)
Create a scalar noise field within a specific range.
minimum (double)
maximum (double)
wavelength (double)

SimplexScalarField

#
public SimplexScalarField(IReader reader)
reader (IReader)

SimplexScalarField

#
public SimplexScalarField(Plane plane, int layers, double minimum, double maximum, double Δφ, double λ, double Δλ)
Create a new simplex noise field.
plane (Plane)Origin and orientation of noise.
layers (int)Number of noise layers (or 'octaves').
minimum (double)Minimum value.
maximum (double)Maximum value.
Δφ (double)Amplitude decay for every subsequent layer.
λ (double)Wavelength for top-most layer.
Δλ (double)Wavelength decay for every subsequent layer.

Properties

FormatLabel

protected string FormatLabel { get; }
Gets the name of this field condensed into a single word, which is how the name appears in formatted values.
inherited fromField

Maximum

#
public double Maximum { get; }

Minimum

#
public double Minimum { get; }

Name

#
public override string Name { get; }
Field.Name

Type

public override FieldType Type { get; }
inherited fromScalarField
Field.Type

Methods

AnalyticalGradientAt

public virtual Vector3d AnalyticalGradientAt(Point3d point)
inherited fromScalarField
point (Point3d)

Format

#
public override string Format()
Field.Format

ModifierArguments

protected Fragments ModifierArguments(string text)
Reduce modifier notation to just the arguments. The labelled form written by Field.Format() ("ScalarNoise min:0 max:1"), the bracketed form ("Scalar Noise (0, 1)") and a bare list of arguments ("0, 1") are all accepted, so that a displayed value can be edited by changing only the parts which matter.
inherited fromField
text (string)Modifier notation.

ScalarAt

#
public override double ScalarAt(Point3d point)
point (Point3d)
Field.ScalarAt

Store

#
public override void Store(IWriter writer)
writer (IWriter)
Field.Store

ToString

#
public override string ToString()
Object.ToString

Trace

public IEnumerable<Point3d> Trace(Point3d start, Angle maximumAngle, DifferentialSolver solver)
Approximate a trajectory through a vector field.
inherited fromField
start (Point3d)Start point of trajectory.
maximumAngle (Angle)Maximum allowed kink angle between segments.
solver (DifferentialSolver)Differential interpolation scheme to use.
Points along the trajectory.

Trace

public IEnumerable<Point3d> Trace(Point3d start, double stepSize, DifferentialSolver solver)
Approximate a trajectory through a vector field.
inherited fromField
start (Point3d)Start point of trajectory.
stepSize (double)Size of intermediate steps.
solver (DifferentialSolver)Differential interpolation scheme to use.
Points along the trajectory.

Trace

public Polyline Trace(Point3d start, double accuracy, double targetLength, DifferentialSolver solver)
Approximate a trajectory through a vector field.
inherited fromField
start (Point3d)Start point of trajectory.
accuracy (double)Accuracy of intermediate steps. When negative, trajectory is traced backwards.
targetLength (double)Length of trajectory.
solver (DifferentialSolver)Differential interpolation scheme to use.
Point at end of trajectory.

TryModify

#
public override Result<Field> TryModify(string text)
Try and create a new field based on this field and modifier notation.

Only the salient properties of a field are exposed to text, the rest are copied from this instance. That is why there is no way to write a field of a specific type from nothing; there has to be one already to serve as the template. Constant scalar and vector fields are the exception, they are entirely described by a number or a vector.

Implementations are expected to accept whatever their Field.Format() writes, so a value can be edited by changing the text it is displayed as. Field.ModifierArguments(string) deals with the label in front of the arguments.

text (string)Modifier notation.
Result of parsing operation.
Field.TryModify

VectorAt

public override Vector3d VectorAt(Point3d point)
Evaluate the field vector component at a specific point in space. If this is a scalar-field, the returned value is *probably* a vector in the form (0,0,scalar), but this is not guaranteed.
inherited fromScalarField
point (Point3d)The point at which to evaluate the field.
The vector value at the given coordinate
