OPENRNDR. A Kotlin/JVM library for creative coding, real-time and interactive graphics

Last update: Dec 29, 2022

Overview

OPENRNDR 0.4

A Kotlin/JVM and Kotlin/JS library for creative coding, real-time and interactive graphics. Can currently be used on Windows, macOS and Linux/x64 to create standalone graphical applications.

Basics and use are further explained in the OPENRNDR guide.

Using OPENRNDR

You are advised to use the OPENRNDR template which provides a quick start to using the library.

OPENRNDR's Javascript/WebGL is still experimental and under development. However, if you feel like trying it you should use the OPENRNDR JS template.

Building OPENRNDR

On a system that has JDK 1.8.x or more recent installed one can run the following commands from a terminal:

cd <path-to-checkout>
./gradlew build

This should start the build process, which will take some time to complete.

Note that OPENRNDR does not depend on anything that is not on Maven Central, builds should be easy and predictable.

Installing OPENRNDR as Maven artifacts

In order to use the OPENRNDR build from your applications one has to install OPENRNDR's Maven artifacts in the local Maven repository.

./gradlew -Prelease.version=0.5.1-SNAPSHOT publishToMavenLocal

Color manipulation
Hello !

When working with color on others langs like JS or Dart you'll find some libraries like

https://gka.github.io/chroma.js

https://github.com/bgrins/TinyColor

I'm looking for an equivalent or recommandation when working with OpenRNDR.

add feature DrawRate
Feature Drawrate() is an extension that allows finer control of the draw loop between the extremes of AUTOMATIC and MANUAL presentation modes.

This is under active development. It currently works for the base general case i.e. DRAWRATE and one special case viz. MINIMISE.

The ffg. key issues still need discussion/resolution.

The context of the coroutine. (program.launch is problematic and GlobalScope.launch is not recommended.)

Special Case UNFOCUS. (use case needs detailing)

Special Case SIZE. (use case needs detailing)

(@edwinRNDR Do you want me to initiate this discussion on the Slack-Development Channel or here?)

I will attach some documentation and example code to this PR for now (it will be the basis of what goes into the Guide when Dokgen becomes available to collaborators!)

P.S. This requires v0.3.31 at minimum.

Creating a ShapeContour .offset() may produce a first segment with NaN value

Describe the bug Calling .offset() on a ShapeContour produces an invalid curve in some cases

To Reproduce

    program {

        val curve = contour {
            moveTo(Vector2(0.1 * width, 0.3 * height))
            continueTo(Vector2(0.5 * width, 0.5 * height))
            continueTo(Vector2(0.9 * width, 0.3 * height))
            continueTo(Vector2(0.1 * width, 0.3 * height))
            close()
        }

        val curve2 = curve.offset(20.0, SegmentJoin.ROUND)

        println(curve2.segments[0])
        println(curve2.segments[1])
        println(curve2.segments[curve2.segments.size-2])
        println(curve2.segments[curve2.segments.size-1])

        extend {
            drawer.contour(curve)
            drawer.contour(curve2) // <-- crash

            drawer.fill = null
            drawer.rectangle(curve.bounds)
            drawer.rectangle(curve2.bounds)
        }
    }

Expected behavior Drawing two offset curves.

Text appears blurred

Describe the bug Text appears blurrier than the characters in the font texture buffer

To Reproduce

import org.openrndr.KEY_ARROW_DOWN
import org.openrndr.KEY_ARROW_UP
import org.openrndr.application
import org.openrndr.draw.loadFont
import org.openrndr.draw.shadeStyle

fun main() = application {
    var fontSz = 8.4
    configure {

                fragmentTransform = """x_fill.gb = vec2(x_fill.r);"""
            }
            drawer.image(font.texture)
            drawer.fontMap = font
            drawer.text("Hello there! #tags @mentions then 3+4*5-6/7...", mouse.position)
        }

        fun changeFontSize(inc: Double) {
            fontSz += inc
            font = loadFont(
                "file:/home/funpro/src/OR/openrndr-template/data/fonts/slkscr.ttf",
                fontSz
            )
            println(fontSz)
        }

        keyboard.keyDown.listen {
            if (it.key == KEY_ARROW_UP) {
                changeFontSize(0.01)
            }
            if (it.key == KEY_ARROW_DOWN) {
                changeFontSize(-0.01)
            }

    }
}

Expected behavior Text should appear as sharp as in the font texture (shown in the image as a grid) but it actually looks quite different.

Fix scaling when using withTarget() and isolatedWithTarget()

If the render target's size was different to the application, the scaling would be incorrect because the projection matrix wasn't adjusted for the render target's size. This should fix that and restore the original matrix when done.

IllegalArgumentException when using ScreenRecorder

Describe the bug A program fails to start with an IllegalArgumentException when the app is extended with ScreenRecorder with some window sizes.

To Reproduce Here is a small snippet of code:

class Demo : Program() {
    override fun setup() {
        extend(ScreenRecorder().apply {
            frameRate = 10
        })

        extend(FunctionDrawer {
            drawer.circle(width / 2.0, height / 2.0, 10.0)
        })
    }
}

fun main(args: Array<String>) {
    application(
            Demo(),
            configuration {
                width = 800
                height = 600
                showBeforeSetup = false
                hideCursor = true
            }
    )
}

If one starts it without modifications, the exception is given:

Exception in thread "main" java.lang.IllegalArgumentException: width (800) and height (599) should be divisible by 2

	at org.openrndr.Application$Companion.run(Application.kt:18)
	at org.openrndr.ApplicationKt.application(Application.kt:56)
	at PostersKt.main(Posters.kt:20)

To fix that one can set height to 601 or disable the ScreenRecorder.

Implement default font so drawer.text can be called directly

Is your feature request related to a problem? If the user calls drawer.text() nothing is visible unless a font is specified earlier

Describe the solution you'd like Maybe text() detects if the font is undefined. In that case it loads a default font. Another option is to load a default font when starting the program, but that would add some start up latency and it's not needed if .text() is never used.

I can try implement it if an approach is suggested.

Bug report: Strokes of primitive shapes are drawn differently compared to contours

OPENRNDR version

32ae9e909d19343df89444de67e43cf7a88a53c9

Java version

Adoptium 17

Describe the Bug

Currently, OPENRNDR is a bit inconsistent when it comes to strokes. This is most apparent when using a semi-transparent stroke color.

When drawing a Rectangle the stroke is drawn over the fill (top-left shape in the screenshot). When drawing a Circle the stroke is drawn outside the fill (bottom-left shape in the screenshot). When drawing a ShapeContour of any kind, the stroke is drawn half-over the fill, leaving the other half outside the fill (top-right and bottom-right shapes in the screenshot). What's more is that Rectangle and Circle are automatically adjusted as to not change their pixels-on-the-screen size when strokeWeight changes, but this is not the case for ShapeContour, where the strokeWeight affects the pixels-on-the-screen size of the shape. This means calling .contour on a Circle and drawing it can create a shape different in size compared to the original Circle (in terms of pixels on the screen).

I believe the ShapeContour currently has the ideal outcome here, as this matches the behavior of strokes in frameworks such as Processing and is most likely how users expect stroke to work. Therefore the drawing of Rectangle and Circle should be changed to be consistent with ShapeContour.

Steps to Reproduce

import org.openrndr.application import org.openrndr.color.ColorRGBa import org.openrndr.draw.isolated import org.openrndr.shape.Circle import org.openrndr.shape.Rectangle fun main() = application { configure { width = 640 height = 640 } program { backgroundColor = ColorRGBa.WHITE val rect = Rectangle(0.0, 0.0, 200.0, 200.0) val circle = Circle(0.0, 0.0, 100.0) extend { drawer.strokeWeight = 8.0 drawer.fill = ColorRGBa.PINK drawer.stroke = ColorRGBa.BLACK.opacify(0.5) drawer.isolated { drawer.translate(100.0, 100.0) drawer.rectangle(rect) drawer.translate(210.0, 0.0) drawer.contour(rect.contour) } drawer.isolated { drawer.translate(200.0, 410.0) drawer.circle(circle) drawer.translate(210.0, 0.0) drawer.contour(circle.contour) } } } }

v0.3.36(Nov 25, 2019)
OPENRNDR 0.3.36

What’s new

A major revamp of VideoPlayerFFMPEG that adds OpenAL based sound support and simple input device listing.

VideoPlayerFFMPEG now has support for seeking.

VideoPlayerFFMPEG will now guess the right FPS when no FPS argument has been passed to VideoPlayerFFMPEG.fromDevice()

VideoPlayerFFMPEG now has draw functions with position and dimension arguments as well as source and target rectangles.

This release uses an OpenGL 4.3 context where available, it will drop back to a 3.3 core context if a 4.3 context can not be created.

The reason for using a 4.3 context is the added support for compute shaders. This release comes with basic (and somewhat experimental) support for compute shaders.

Program has an added deltaTime property that reflects that time (in seconds) since the last screen refresh.

Added support for 3D Beziers through Path3D an Segment3D. Drawer now has added path and segment primitives.

Added a point primitive to Drawer.

A shutdown() function has been added to the Extension class. Shutdown is called whenever an OPENRNDR application exits.

Added support for integer samplers.

Added extra constructors to Vector2, Vector3, Vector4 that allow GLSL like construction. For example one can now write Vector3(2.0) which is a short-hand for Vector3(2.0, 2.0, 2.0)

Added invoke() functions to Vector2, Vector3, Vector4, ColorRGBa, ColorHSVa, ColorHSLa that work exactly like the copy function but should be more convenient to use.

Added a Polar class that works analogous to the Spherical class.

Made the coroutine dispatcher code part of the public API, you can now create public dispatchers in an OPENRNDR program using the Dispatcher class.

Several tweaks and fixes to improve orx-olive

Upgraded LWJGL to 3.2.3 and Bytedeco JavaCPP to 1.5.2
