MutableParallelogram

public MutableParallelogram()

Constructs an empty MutableParallelogram with a center at the origin, a zero width, a zero height, zero rotation, and zero shear factor. This is intended for subsequent population with one of the populateFrom methods.

public float getHeight()

A Parallelogram may have a positive or negative height; a positive height indicates that the angle from the first semi-axis to the second will also be positive.

public float getShearFactor()

A Parallelogram] may have a positive or negative shear factor; a positive shear factor indicates a smaller absolute angle between the semi-axes (the shear factor is, in fact, the cotangent of that angle).

public @FloatRange(from = 0.0) float getWidth()

A Parallelogram may not have a negative width. If an operation on a parallelogram would result in a negative width, it is instead normalized, by negating both the width and the height, adding π to the angle of rotation, and normalizing rotation to the range [0, 2π).

public final @NonNull MutableParallelogram populateFrom(@NonNull Parallelogram input)

Fills this MutableParallelogram with the same values contained in input.

Returns the modified instance to allow chaining calls.

public final @NonNull MutableParallelogram populateFromCenterAndDimensions(
    @NonNull MutableVec center,
    @FloatRange(from = 0.0) float width,
    float height
)

Populates a MutableParallelogram to have a given center, width and height. The resulting Parallelogram has zero rotation and shearFactor. If the width is less than zero, the Parallelogram will be normalized.

public final @NonNull MutableParallelogram populateFromCenterDimensionsAndRotation(
    @NonNull MutableVec center,
    @FloatRange(from = 0.0) float width,
    float height,
    @AngleRadiansFloat float rotation
)

Populates the MutableParallelogram to have a given center, width, height and rotation and zero shearFactor. If the width is less than zero or if the rotation is not in the range [0, 2π), it will be normalized.

public final @NonNull MutableParallelogram populateFromCenterDimensionsRotationAndShear(
    @NonNull MutableVec center,
    @FloatRange(from = 0.0) float width,
    float height,
    @AngleRadiansFloat float rotation,
    float shearFactor
)

Populates the MutableParallelogram to have a given center, width, height, rotation and shearFactor. If the width is less than zero or if the rotation is not in the range [0, 2π), it will be normalized.

public final @NonNull MutableParallelogram populateFromSegmentAndPadding(@NonNull Segment segment, float padding)

Populates the MutableParallelogram to be aligned with the segment with its bounds padding units away from the segment and shear of zero.

public void setHeight(float height)

A Parallelogram may have a positive or negative height; a positive height indicates that the angle from the first semi-axis to the second will also be positive.

public void setShearFactor(float shearFactor)

A Parallelogram] may have a positive or negative shear factor; a positive shear factor indicates a smaller absolute angle between the semi-axes (the shear factor is, in fact, the cotangent of that angle).

public void setWidth(float width)

A Parallelogram may not have a negative width. If an operation on a parallelogram would result in a negative width, it is instead normalized, by negating both the width and the height, adding π to the angle of rotation, and normalizing rotation to the range [0, 2π).
