Constructors

StrategyCamera(double, double, float, float, Func<DoubleVector3, double>)

Creates a new strategy camera.

public StrategyCamera(double minRadius, double maxRadius, float minAngle, float maxAngle, Func<DoubleVector3, double> heightController)

Parameters

minRadius double

The minimum radius allowed. Also used as the initial radius

maxRadius double

The maximum radius allowed.

minAngle float

The minimum vertical angle in degrees. Effective when Radius is equal to MinRadius.

maxAngle float

The maximum vertical angle in degrees. Effective when Radius is equal to MaxRadius.

heightController Func<DoubleVector3, double>

This delegate is called to control the minimum height of the strategy camera based on its 2D coordinates.

Properties

HorizontalRotation

The horizontal rotation in degrees.

public float HorizontalRotation { get; set; }

Property Value

float

Remarks

Must be a real number.

MaxAngle

The maximum vertical angle in degrees. Effective when Radius is equal to MaxRadius.

public float MaxAngle { get; set; }

Property Value

float

Remarks

Must be a real number.

MaxRadius

The maximum radius allowed.

public double MaxRadius { get; set; }

Property Value

double

Remarks

Must be a positive real number.

MinAngle

The minimum vertical angle in degrees. Effective when Radius is equal to MinRadius.

public float MinAngle { get; set; }

Property Value

float

Remarks

Must be a real number.

MinRadius

The minimum radius allowed.

public double MinRadius { get; set; }

Property Value

double

Remarks

Must be a positive real number.

Radius

The distance between the camera and the center of the focues object.

public double Radius { get; set; }

Property Value

double

Remarks

Must be a positiv real number.

Target

The position the camera is looking at.

public override DoubleVector3 Target { get; set; }

Property Value

DoubleVector3

Exceptions

ArgumentOutOfRangeException

The coordinates lie outside the range of the height-controlling terrain.

Methods

PerspectiveChange(float, float, float, float)

Called when the user changes the view perspective.

public override void PerspectiveChange(float panX, float panY, float rotation, float zoom)

Parameters

panX float

The number of pixels panned along the X-axis divided by the number of pixels of the longest side of the viewport.

panY float

The number of pixels panned along the Y-axis divided by the number of pixels of the longest side of the viewport.

rotation float

Horizontal rotation in degrees.

zoom float

Scaling factor; 1 for no change, must not be 0.

UpdateView()

Update cached versions of View and related matrices.

protected override void UpdateView()
