Google's Tilt Brush is a virtual reality tool that allows a person to paint with light that stays where that person puts it for viewers to see wearing a Virtual Reality Headset, according to a report by New York Times. It was released as a free add-on to the HTC Vive.

The Tilt Brush was created by Drew Skillman and Patrick Hackett, both were video game developers and later turned into virtual reality enthusiasts. They were developing a 3-D chess application when they noticed that as they move the chess pieces around the virtual space, it left trails of light behind. Skillman and Hackett abandoned the chess idea and started to focus on that trail of light, hoping they can develop a tool with it for drawing in 3-D.

A few months later, Google bought Skillman and Hackett's company for an undisclosed amount. With Google supporting the project, it attracted other developers and evolved the Tilt Brush into a refined tool for drawing, painting and sculpting in virtual reality.

The tool got its name from earlier versions wherein a user must draw on a two-dimensional surface that has to be tilted in any direction in virtual space. However, with the help of HTC Vive with a pair of hand-held controllers, the user may now able to draw anywhere within a room-sized area.

According to Digital Trends, the Tilt Brush is used in Google's initiative to help artists create in 3-D called the Tilt Brush Artist in Residence Program (AiR). Artists from different fields including painters, illustrators and even graffiti artists use the Tilt Brush as their primary tool. Google wants to include more artists in their program and add their art to its showcase.
