Both releases pack more than a year’s worth of features, improvements and bug fixes. There is quite a bit to unpack here. I will start listing some of my personal favorites: - Improved quality of the Bezier polygon (Shape) clipper - The new `hobbyCurve` feature - The new `Shape.scatter()` feature I will update this post with images and code! I also invite anyone to showcase their favorite 0.4.0 features! ---

🎉 # 485 commits! That’s the number of commits in this release if I counted them correctly. Big thank you to Edwin for the huge effort and to the RNDR Studio for creating OPENRNDR and making it Free Software 🙂 And thanks to everyone who contributes and uses it. It makes me happy to be part of this growing family. # ⚡ ApplicationPreload This is one feature I enjoy in OPENRNDR 0.4.0. It allowed me to add screenshots, video exporting and pressing ESC to quit to hundreds of programs in a project at once, instead of repeating the code in every program. # ⚡ Video export pause and resume Adding video exporting by default required to actually not export video until I press a key (to avoid filling my drive with video files) and then be able to _start, pause and resume video exporting_. This is possible thanks to the `screenRecorder.outputToVideo` boolean. Both features are described in [Enable Screenshots, ScreenRecorder and more in all programs by default](https://openrndr.discourse.group/t/enable-screenshots-screenrecorder-and-more-in-all-programs-by-default/384) ---

## ⚡ `Rectangle.grid()` now with cell dimensions The `.grid()` method makes it easy to convert a `Rectangle` into a `List>`. Previously one could specify the number of columns and rows by using `Int` arguments, but with ORX 0.4.0 one can also specify the dimensions of the cells by using `Double` values. This makes it easy to define cell sizes with specific aspect ratios (for example, squares). The number of resulting columns and rows is calculated by the library according to the the requested cell dimensions, gutter values and window size. ```kotlin import org.openrndr.application import org.openrndr.color.ColorRGBa import org.openrndr.extra.shapes.grid fun main() = application { configure { width = 750 height = 250 } program { extend { drawer.clear(ColorRGBa.PINK) drawer.fill = ColorRGBa.WHITE drawer.stroke = null drawer.bounds.grid( 100.0, 100.0, 10.0, 10.0, 10.0, 10.0 ).flatten().forEach { drawer.rectangle(it) } } } } ``` ![2022-07-14-162032_750x250_scrot](https://global.discourse-cdn.com/free1/uploads/openrndr/original/1X/ee6a7e5f2d2988bdab99927269123e4a014cc20d.png) Another example using this feature ([source code](https://github.com/openrndr/orx/pull/223/files#diff-3b3b6d8071b7797ccd62c5b26269e0de856faee040e5b18d6e27eb3b7252c47c)). ![image](https://global.discourse-cdn.com/free1/uploads/openrndr/original/1X/ea155ed2c09df1b84a0ee1e9c8a8863fa00df203.png) ---

Here a quick demo showing how `myShapeContour.hobbyCurve()` converts polygonal contours into smooth contours. The bézier control points are made symmetric thanks to John Hobby’s algorithm. ![apps2022.HobbyDemo-2022-08-21-13.14.16](https://global.discourse-cdn.com/free1/uploads/openrndr/original/1X/028e55ad465a8e5c2e523f5a4cf5b1db47e69427.jpeg) > **imports** > > ```kotlin > import org.openrndr.Fullscreen > import org.openrndr.application > import org.openrndr.color.ColorRGBa > import org.openrndr.extra.noise.Random > import org.openrndr.extra.shapes.grid > import org.openrndr.extra.shapes.hobbyCurve > import org.openrndr.math.Polar > import org.openrndr.shape.ShapeContour > > ``` ```kotlin fun main() = application { configure { fullscreen = Fullscreen.CURRENT_DISPLAY_MODE } program { extend { Random.seed = "bkwd" drawer.clear(ColorRGBa.WHITE) drawer.bounds.grid(4, 4, 50.0, 50.0, 50.0, 50.0).flatten().forEachIndexed { i, rect -> val count = i + 2 // points with even angular spacing and randomized radius val points = List(count) { rect.center + Polar(it * 360.0 / count, rect.width * Random.double(0.1, 0.4)).cartesian } val pointyContour = ShapeContour.fromPoints(points, true) val smoothContour = pointyContour.hobbyCurve() drawer.fill = ColorRGBa.PINK drawer.contour(smoothContour) drawer.stroke = ColorRGBa.BLACK.opacify(0.4) drawer.fill = ColorRGBa.BLACK.opacify(0.2) drawer.contour(pointyContour) drawer.fill = ColorRGBa.RED drawer.circles(points, 5.0) } } } } ``` ---

Another new feature mentioned by Edwin above is the `Shape.scatter()` function, which allows to fill shapes with 2D points while keeping the specified distance to other points and to the edge of the shape. ![image](https://global.discourse-cdn.com/free1/uploads/openrndr/original/1X/3500d99643c83abd838a0a9fd7655d179b176e9c.png) > **imports** > > ```kotlin > import org.openrndr.application > import org.openrndr.color.ColorRGBa > import org.openrndr.extra.noise.scatter > import org.openrndr.extra.shapes.hobbyCurve > import org.openrndr.math.Polar > import org.openrndr.shape.ShapeContour > > ``` ```kotlin fun main() = application { program { val star = ShapeContour.fromPoints(List(15) { Polar(it * 360.0 / 15.0, (it % 3) * 100.0 + 100.0).cartesian }, true).hobbyCurve().shape val points = star.scatter(placementRadius = 20.0, distanceToEdge = 30.0) extend { drawer.clear(ColorRGBa.WHITE) drawer.translate(drawer.bounds.center) drawer.stroke = null drawer.fill = ColorRGBa.PINK drawer.shape(star) drawer.fill = ColorRGBa.WHITE drawer.circles(points, 16.0) } } } ```
