A simple OPENRNDR program
Here we show a very simple program written using OPENRNDR.
import org.openrndr.application
import org.openrndr.color.ColorRGBa
import kotlin.math.abs
import kotlin.math.cos
fun main() = application {
program {
extend {
drawer.clear(ColorRGBa.PINK)
drawer.fill = ColorRGBa.WHITE
drawer.circle(drawer.bounds.center, abs(cos(seconds)) * height * 0.51)
}
}
}
