API

Property Type Default Description
audioSource selector/attribute * A-Sound element.
fftSize int 256 A non-zero power of two up to 2048, representing the size of the FFT.
colors array '#f4ee42', '#41f468', '#41dff4' Array of colors used to describe the frequency.
points int 100 Number of points to be plotted.
pointSize int 1 Size of individual points.
detail int 100 How many material objects to use.
scale int 1 The coordinates of each point will be multiplied by this number.
logValues boolean false Set to true to log the x, y, and z values of the points to the console.
x string/javascript t The function used to determine the x axis of each point based on t.
y string/javascript t The function used to determine the y axis of each point based on t.
z string/javascript t The function used to determine the z axis of each point based on t.

Example

<a-sound src='src: url(../music/song.mp3)' position='0 0 -10' id='audio' autoplay='true'></a-sound>
 
<a-entity audioSource='#audio' fractal='points: 200; x: Math.sin(t) * (t^2); z: Math.sin(t^2);' position='0 140 0' rotation='0 0 180'></a-entity>

Instructions

To plot a set of points, you have define f(t) for x, y, and z. In the example at the top of this page I defined f(t) for z as Math.sin(t^2). For each 200 points, it will increment t by 1 and return the value of f(t) in the case of z.

Previous points

Most attractors determine their values based on the coordinates of the last point. To access the last point that was plotted, simply include prev.x, prev.y, or prev.z in your f(t) function.
