## Demos
### adjust/DemoAdjustContour01

Demonstrates how to use `adjustContour` to select and modify three vertices
in a circular contour. In OPENRNDR circles contain 4 cubic bézier
segments connecting 4 vertices.

On every animation frame the circular contour is created and transformed
using sines, cosines and the variable `seconds` for an animated effect.

### adjust/DemoAdjustContour02

Demonstrates how to use `adjustContour` to select and remove vertex 0
from a circular contour, then select and animate the position and scale the new vertex 0.

### adjust/DemoAdjustContour03

Demonstrates how to select and alter the edges of a rectangle.

The rectangle is a scaled-down version window bounds.

By default, the edges of a rectangular contour are linear, so the `edge.toCubic()` method
is called to make it possible to bend them.

Then various edges are selected one by one and transformed over time using operations like
scale, rotate, splitAt and moveBy.

[source code](src/jvmDemo/kotlin/adjust/DemoAdjustContour03.kt)

### adjust/DemoAdjustContour04

Demonstrates an `adjustContour` animated effect where edge 0 of a contour
is replaced by a point sampled on that edge. The specific edge point oscillates between
0.0 (at the start of the segment) and 1.0 (at the end) using a cosine and the `seconds` variable.

The base contour used for the effect alternates every second
between a rectangular and a circular contour.

[source code](src/jvmDemo/kotlin/adjust/DemoAdjustContour04.kt)

### adjust/DemoAdjustContour05

Demonstrates animated modifications to a circular contour using `adjustContour`.

The application creates a circular contour and dynamically alters its edges
based on the current time in seconds. Each edge of the contour is selected
and transformed through a series of operations:

- The currently active edge (based on time modulo 4) is replaced with a point at 0.5.
- All other edges are reshaped by reducing their length dynamically, with the reduction
calculated using a cosine function involving the current time in seconds.

The resulting contour is then drawn with a red stroke color.

[source code](src/jvmDemo/kotlin/adjust/DemoAdjustContour05.kt)

### adjust/DemoAdjustContour06

Demonstrates the use of `adjustContour`
to create an animated effect where edges are split, vertices are selected,
and transformations such as scaling are applied.

The program creates a circular contour which is modified on each animation frame.

- Edges of the circular contour are split dynamically based on a time-based cosine function.
- Newly created vertices are selected and scaled around the center of the contour
using time-dependent transformations.

The selection of vertices happens automatically thanks to
`parameters.clearSelectedVertices` and `parameters.selectInsertedVertices`

The modified animated contour is finally drawn.

[source code](src/jvmDemo/kotlin/adjust/DemoAdjustContour06.kt)

### adjust/DemoAdjustContour07

Demonstrates how to create and manipulate a contour dynamically using the `adjustContour` function.

The program initializes a simple linear contour and applies transformations to it on each animation frame:
- The only edge of the contour is split into many equal parts.
- A value between 0 and 1 is calculated based on the cosine of the current time in seconds.
- That value is used to calculate an anchor point and to select all vertices to its right
- The selected vertices are rotated around an anchor, as if rolling a straight line into a spiral.

[source code](src/jvmDemo/kotlin/adjust/DemoAdjustContour07.kt)

### adjust/DemoAdjustContour08

Demonstrates how to adjust and manipulate the vertices and edges of a contour.

This method shows two approaches for transforming contours:

1. Adjusting vertices directly by selecting specific vertices in a contour and modifying their control points.
2. Adjusting edges of a contour by transforming their control points.

For each approach, a red line is drawn representing the transformed contour.

[source code](src/jvmDemo/kotlin/adjust/DemoAdjustContour08.kt)

### adjust/DemoAdjustContour09

Demonstrates how to manipulate a contour by adjusting and transforming its vertices
and edges, and subsequently visualizing the result using different drawing styles.

The program creates a rectangular contour derived by shrinking the bounds of the drawing area.
It then applies multiple transformations to selected vertices. These transformations include:

- Averaging tangents for selected vertices
- Scaling and rotating vertex positions based on the horizontal mouse position
- Switching tangents for specific vertices

The resulting contour is drawn in black. Additionally:

- Control line segments are visualized in red, connecting segment endpoints to control points.
- Vertices are numbered and highlighted with black-filled circles.
- Tunni lines, which represent optimized control line placements, are visualized in cyan.
- Tunni points, marking the Tunni line's control, are emphasized with yellow-filled circles.

[source code](src/jvmDemo/kotlin/adjust/DemoAdjustContour09.kt)

### adjust/DemoAdjustContourContinue01

Demonstrates how to adjust and animate contour segments and vertices.

The method initially creates a contour by offsetting the edges of the window's bounds. A process is
defined to sequence through various transformations on the contour, such as selecting edges, selecting
vertices, rotating points, or modifying segment attributes based on mathematical transformations.

The adjusted contour and its modified segments and vertices are iterated through a sequence
and updated in real time. Rendering involves visualizing the contour, its control points, the
Tunni lines, Tunni points, as well as the selected segments and points with distinct styles
for better visualization.

The complex animation sequence is implemented using coroutines. Two loops in the code alternate
between rotating vertices and adjusting Tunni lines while the `extend` function takes care of
rendering the composition in its current state.

The core elements to study to in this demo are `adjustContourSequence` and `launch`.

### alphashape/DemoAlphaShape01

Demonstrates the use of [AlphaShape] to create a [org.openrndr.shape.ShapeContour] out
of a collection of random [Vector2] points. Unlike the convex hull, an Alpha shape can be concave.

More details in [WikiPedia](https://en.wikipedia.org/wiki/Alpha_shape)

### alphashape/DemoAlphaShape02

Demonstrates the use of [AlphaShape] to create ten
[org.openrndr.shape.ShapeContour] instances out of a collection of random [Vector2] points.

The same points are used for each contour, but an increased alpha parameter
is passed to the AlphaShape algorithm. Higher values return more convex shapes
= shapes with a larger surface.

The list of shapes is reversed to draw the smaller contours on top, otherwise only
the last one would be visible.

An instance of [Random] with a fixed seed is used to ensure the resulting
random shape is always the same.

of rectangles, which are generated and manipulated based on time and random parameters. The application
follows these steps:

1. Initializes a random generator seeded with the elapsed seconds since the start of the program.
2. Creates a sequence of rectangles using the `uniformSub` function to generate random sub-rectangles
within the bounding rectangle of the canvas.
3. Distributes the generated rectangles horizontally within the canvas using the `distributeHorizontally` method.
4. Aligns the rectangles vertically according to their position in relation to the bounding rectangle
and a dynamic anchor point derived from the cosine of elapsed time.
5. Renders the rectangles on the canvas in the output window.
