Constructors

RotationF

public RotationF(float horizontal, float vertical)

Create a new set of rotation angles.

Parameters:

horizontal (float)
vertical (float)

RotationF

public RotationF(PointF from, PointF to)

to (PointF)

Properties

Empty

public static RotationF Empty { get; }

Gets an empty rotation, which represents the topdown view.

Horizontal

public float Horizontal { get; }

Gets the horizontal rotation factor.

IsEmpty

public bool IsEmpty { get; }

Gets whether this rotation is empty.

IsValid

public bool IsValid { get; }

Gets whether this rotation is valid.

Standard

public static RotationF Standard { get; }

Gets a standard rotation with a decent 3d projection.

Unset

public static RotationF Unset { get; }

Gets an unset rotation.

Vertical

public float Vertical { get; }

Gets the vertical rotation factor.

Methods

ToTransform

public Transform ToTransform()

Create a Rhino transformation matrix based on this rotation.

ToTransform

public Transform ToTransform(Function angleMap, double perspective = 0)

Create a Rhino transformation matrix based on this rotation.

Parameters:

angleMap (Function)

Angle mapping function.

perspective (double = 0)

Perspective strength.

0.0 = no perspective.

0.15 = subtle perspective.

0.3 = weak perspective.

0.6 = medium perspective.

1.0 = full perspective.

ToTransform

public Transform ToTransform(Function angleMap, RectangleF frame, double diagonal, double perspective = 0)

Create a Rhino transformation matrix based on this rotation and a dilation/translation into a target frame.

Parameters:

angleMap (Function)	Angle mapping function.
frame (RectangleF)	Frame for object display.
diagonal (double)	Length of object boundingbox diagonal.
perspective (double = 0)	Perspective strength. 0.0 = no perspective. 0.15 = subtle perspective. 0.3 = weak perspective. 0.6 = medium perspective. 1.0 = full perspective.

ToTransform

public Transform ToTransform(int minimumAngle, int maximumAngle, double perspective = 0)

Create a Rhino transformation matrix based on this rotation.

Parameters:

minimumAngle (int)

Lowest allowed angle in degrees (0=straight down, 90=horizontal, 180=straight up).

maximumAngle (int)

Highest allowed angle in degrees (0=straight down, 90=horizontal, 180=straight up).

perspective (double = 0)

Perspective strength.

0.0 = no perspective.

0.15 = subtle perspective.

0.3 = weak perspective.

0.6 = medium perspective.

1.0 = full perspective.

ToTransform

public Transform ToTransform(int minimumAngle, int maximumAngle, RectangleF frame, double diagonal, double perspective = 0)

Create a Rhino transformation matrix based on this rotation and a dilation/translation into a target frame.

Parameters:

minimumAngle (int)	Lowest allowed angle in degrees (0=straight down, 90=horizontal, 180=straight up).
maximumAngle (int)	Highest allowed angle in degrees (0=straight down, 90=horizontal, 180=straight up).
frame (RectangleF)	Frame for object display.
diagonal (double)	Length of object boundingbox diagonal.
perspective (double = 0)	Perspective strength. 0.0 = no perspective. 0.15 = subtle perspective. 0.3 = weak perspective. 0.6 = medium perspective. 1.0 = full perspective.
