Demonstrates the use of Arrangement to create a 2D arrangement of shapes.
|

|

The Arrangement constructor takes as arguments instances of [org.openrndr.shape.ShapeProvider]s.

Once constructed, we can request `originFaces`, `edges`, `vertices`, `boundaries` and `holes`,

to render or manipulate them further as needed.

Demonstrates the use of Arrangement to create a 2D arrangement of shapes using a self-intersecting curve.
|
||||
|

For self-intersections we need to pass the same curve twice as arguments to Arrangement.
|
||||
The specific curve used results in 4 intersection points.
|

|

This demo shows how we can query and visualize the neighborhoods of those 4 vertices.

`boundedFaces` elements have a `contour` property, while `unboundedFaces` do not.

In this example, `faces` contains 25 items: 24 `bounded` and 1 `unbounded` faces.

Demonstrates how to draw a bezier patch and its corresponding contours.
|

The bezier patch is generated from a circular shape and is assigned colors

for each control point. The patch is subdivided into horizontal and vertical
|

contours, which are rendered to visualize the structure of the bezier patch.
|

The bezier patch constructor expects a contour with 4 segments, for example

a rectangular contour or a circle, which in OPENRNDR is made out of 4 segments.

|

|

Demonstrates how to render a grid of bezier patches that morph between a rectangle and
|
||||
a rotated circle contour.
|
||||
These shapes are transformed into bezier patches, and their colors are interpolated through a blend
|
||||
factor calculated for each cell in the grid.
|
||||
|
||||
The grid layout contains 4 columns and 4 rows with margins and gutters.
|

Each cell's center serves as the drawing position for a blended bezier patch.

Demonstrates how to create and render a bezier patch with randomized control points

Animated demonstration of uniform contour blending. Once a `ContourBlend` between two

Demonstration of non-uniform contour blending
|
||||
|
||||
The `mix` method of a `ContourBlend` does not only accept a Double, but also a function.
|
||||
This function should take one Double argument, which specifies the normalized `t` value between
|
||||
the start and the end of the contour, and should return a normalized value indicating the
|
||||
morphing state between the first contour and the second contour, for that specific t value.
|
||||
|
||||
This allows us, for instance, to morph one part of the shape first, then have other parts follow.
|
||||
|
||||
This demo shows a grid of 9 contours which are part circle and part 5-point start.
