OUTRUN VR Visuals is a virtual reality (VR) music visualisation. Choosing a real-time music visualisation over a pre-rendered movie demands performance everytime it is played, but allows changes and re-usage of the content, even though a finished movie would run smoothly on nearly every device. There is also no bigger interaction possible with a finished movie. Ignoring the optimization issues on some mobile handhelds, this project shows a daily use case for VR. It also gives the user a new music experience. It technically runs with every kind and type of music.

Generate endless World

Implementation of a chunk generator, fed by a perlin noise generator to build up an endless world as starting point. Subdividing into cached chunks helps to only render seen parts of the world and to improve overall performance.

Differentiate Frequency bands

The implementation of Fast Fourier transform is a major key to audio visualisation. By dividing the 512 scanned frequencies to eight bands, the raw sound data gets more usable.

Making the environment react to music

Injection of the noise generator by using another frequency band’s amplitude for the mesh buildup makes the landscape react to the music.

Particel System

Adding a simple particel system as a ring of fog around the player improves the immersion.

Instantiate objects

The Random-Instantiate script spawns objects depending on multiple set data.
