Functions

operator fun contains(point: Vector2): Boolean

Returns true if given point lies inside the Shape.

open operator override fun div(scale: Double): Circle

open operator override fun minus(right: Circle): Circle

open override fun movedBy(offset: Vector2): Circle

Creates a new shape with the same size but the current position offset by the given amount.

open override fun movedTo(center: Vector2): Circle

Creates a new Circle with center at center.

open operator override fun plus(right: Circle): Circle

open override fun position(u: Double, v: Double): Vector2

Returns a position in the bounding box for parameterized values u and v between 0.0 and 1.0 where (0.5, 0.5) is the center of the bounding box.

open fun position(uv: Vector2): Vector2

Returns a position in the bounding box for a parameterized uv value between (0.0, 0.0) and (1.0, 1.0) where (0.5, 0.5) is the center of the bounding box.

open override fun scaledBy(scale: Double, uAnchor: Double, vAnchor: Double): Circle

Creates a new shape with dimensions scaled by scale.

open override fun scaledTo(radius: Double): Circle

Creates a new Circle at the same position with the given radius.

fun tangents(point: Vector2): Pair<Vector2, Vector2>

Calculates the tangent lines through an external point.

fun tangents(other: Circle, isInner: Boolean = false): List<Pair<Vector2, Vector2>>

Calculates the tangent lines between two Circles.
