MutableParallelogram

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

Constructs a MutableParallelogram with 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 static final @NonNull MutableParallelogram fromCenterDimensionsAndRotation(
    @NonNull MutableVec center,
    @FloatRange(from = 0.0) float width,
    float height,
    @AngleRadiansFloat float rotation
)

Constructs a MutableParallelogram with a given center, width, height and rotation. The resulting Parallelogram has zero shearFactor. If the width is less than zero or if the rotation is not in the range [0, 2π), the Parallelogram will be normalized.

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

Constructs a MutableParallelogram with 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), the Parallelogram will be normalized.

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 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).
