MutableParallelogram

fun fromCenterAndDimensions(
    center: MutableVec,
    width: @FloatRange(from = 0.0) Float,
    height: Float
): MutableParallelogram

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.

fun fromCenterDimensionsAndRotation(
    center: MutableVec,
    width: @FloatRange(from = 0.0) Float,
    height: Float,
    rotation: @AngleRadiansFloat Float
): MutableParallelogram

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.

fun fromCenterDimensionsRotationAndShear(
    center: MutableVec,
    width: @FloatRange(from = 0.0) Float,
    height: Float,
    rotation: @AngleRadiansFloat Float,
    shearFactor: Float
): MutableParallelogram

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.

open var height: Float

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.

open var shearFactor: Float

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).

open var width: Float

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).
