Real-time rendering is the future of computer animation

Epic Games, the company behind Unreal Engine 4, is showing off its brand-new real-time rendering technology, and with it the future of game and animation development. The company is set to unleash two real-time production videos next week at SIGGRAPH, a computer graphics event.

You might not be familiar with Unreal Engine 4, but you’re probably aware of it’s work. Video games like Fortnite, Kingdom Hearts III, and Sea of Thieves are built with it. Movies like War For The Planet of The Apes , and Emmy Award-winning TV shows like Disney’s Amigo use it as well.

Epic Games will use the free game engine to show off a high-fidelity trailer for the video-game Fortnite. The trailer is one of two videos Epic Games will present that feature real-time production. Co-directors Michael Clausen and Gavin Moran said:

We had this mandate to showcase all these things with Unreal Engine 4 and Fortnite, we wanted to touch on all the important aspects of the game-play, and focus on the characters, all in engine. We also had to make it a compelling story in three-minutes, and all of it had to be done with real-time production.

The real-time production aspect is the result of new technology that affects every aspect of development in the engine. Once the designers created the characters and props that would be used in the trailer they were able to import and then experiment without having to constantly stop for rendering.

This new process is far more interactive. Traditionally time-intensive actions like camera placement, lighting, and color effects can be rendered in real-time. This allows the director – or co-directors in this case – to work more like a film director would on a set.

The upgrades to Unreal Engine are further inroads to creating photo-realistic games with characters that appear to live and breathe. The trailer for Kingdom Hearts III features a Toy Story world that looks better than the one Pixar created…
