What is real-time technology and how it improves projects?

Real-time rendering is a process that is rendering and displaying frames on the fly. It's like watching the frame of a movie being rendered as you're making it, rather than waiting until the end to see how everything turned out.

The technology has been around for a while—it first came about with video games and CGI movies in the '90s. But now it's become much more accessible for artists and animators who want to see their work as it's happening, without waiting hours or days before seeing their results.

What is real-time?

Real-time rendering is the process of creating a visual representation of a scene from a model or description, in real time. The real-time aspect of this can be experienced when you run a video game and move your character around the world, or when you see an animation on your smartphone that responds to your touch.

The idea is that you can use it to create anything from a simple animation to a full-blown video game. The process is similar to pre-rendering, but it allows for dramatic changes and improvements in the quality of your videos.

Why use real-time?

You can see how your work will look faster, and experiment with different options quickly.

It allows for more experimentation, so you can get feedback from clients and stakeholders before committing to any final decisions. This makes it easier to make changes on the fly during an iterative process, which in turn helps keep costs down because you're not wasting time or money on unnecessary rework.

Benefits:

  • Possibility of creating photorealistic images in real-time.
  • Full creative control of the final quality of the image on the fly.
  • The results are deliverable faster.
  • It's a great opportunity for filmmakers with virtual production.

Does it replace traditional rendering?

Real-time is used for visual effects, game development, and other applications that require high-quality visuals. It is also very flexible and can be used for a wide variety of applications.

Traditional rendering has been the standard in creating high-quality content for many years now. This process involves capturing an image from each angle of the subject being rendered, and then outputting a final product that looks exactly like you want it to look. It can take hours or even days to render out your project, which makes it difficult if you need something done quickly or if you want multiple versions of your project rendered at once (for example, different lighting conditions).

Real-time allows us to create images comparable in quality to traditional rendering but without all the time-consuming steps involved with traditional methods of producing graphics such as changing lights, shadows, reflections etcetera.

Is real-time rendering expensive?

Real-time projects are not necessarily more expensive than offline ones. It all depends on your needs and what kind of software are you using.
Working on projects in a real-time tool like Unreal Engine could be more expensive than offline ones, but offline rendering has some disadvantages:

  • Waiting for previews and final material.
  • Costs of rendering—you have to own a really expensive graphic card or spend money on render farms to do it quickly (but still it could be hours or days).
  • It takes more time to do minor changes.

Our clients benefit greatly from working with real-time software. Making corrections, deliveries and even collaborating together in live sessions increases productivity while allowing everyone to see the results immediately.
There's no limit to what can be achieved with this technology, giving you the potential for a major edge over your competitors.

Conclusion

It's an incredible tool for bringing technology to life. It gives us the ability to create vibrant, captivating visuals and interactive simulations that range from games and animated effects all the way up to virtual production in the film—giving any storyteller more options than ever before!

With Unreal Engine at your disposal, it's time to push the boundaries of what we think computers can do!
