Current technology and available software has elevated rendering from an industry once reserved only for computer geeks to a rapidly expanding field that includes artists, architects, engineers, developers and pretty much everything else under the sun. But, there are limits to that technology that have those professionals running into walls when it comes to making the next big leap into mainstream rendering and visualization.
Real Time Rendering is pretty much exactly what it sounds like: animations that are rendered so quickly they appear to be being generated in absolute real time. The pipeline represents the foundation of any visualization or rendering engine. It is where the rendering of all 3D objects, light sources, lighting models, textures, cameras and more happens. Specifically, the real-time rendering pipeline consists of three conceptual stages: the application stage, the geometry stage, and the rasterizing stage.
Now, real-time rendering is nothing new. The videogame industry has been implementing real-time rendering in games for decades, but only recently have designers and architects started using some of those techniques to present their ideas. Sounds like a no-brainer right? The ability to hand your client a PS4 controller and give them an interactive virtual tour of where their money is about to be poured into is on a whole other level of multimedia presentations.
But why has it take so long for the design and architecture industries to adapt this technology? Why are so many firms stuck in the stone age with static images and spliced together animations that read more like diagrams than immersive representational experiences?
Developing even a simple scene that can be interacted with at the most fundamental level is expensive and time consuming. This price of admission is an immediate turn-off to most architecture and design firms who have a limited amount of time and money to put together a design presentation, and will almost never spend it on something so extravagant. The other answer - the answer I believe to be more true than simply money - is that architects have no idea how to implement this type of experience.
In a profession where control is often your only ally, relinquishing that control to someone who might not understand the design on a fundamental or even surface level is as ludicrous as not wearing a black turtleneck to work today. Due to the limitations of the static rendering image, this process can be slow, requiring a lot of back and forth. Real-time rendering makes this process easier by generating the images in less than a second. Real-time rendering is an important stepping stone in making the design process better, by providing major control to the client during the presentation and breaking the continuous chain of just trial and feedback without satisfaction and running out of resources, time and money.
The feedback goes from being a preconceived judgment of a static object to an unpredictable emotional and physiological response to something that assaults the senses with information regarding light, space, material, and procession simultaneously. Real-time rendering has the potential to add layers of depth and output that will have designers reacting and making design decisions based on an almost analogous experience.

With Real-time 3D rendering now becoming a commonplace in TV shows and feature films, clients expect the same level of quality in their architectural presentations. Advances in rendering technology have not only made real-time renderings possible but also have cut short the time taken by this process to more than half. Simply taking each part of your workflow that uses traditional rendering and replacing it with real-time rendering will save time.
That alone is attracting many designers toward real-time rendering. Real-time rendering provides additional benefits such as the ability to iterate and collaborate more effectively, leading to greater freedom of creativity. For companies and professionals looking to gain a competitive advantage, real-time rendering can make all the difference.
This has become an integral and effective part of their workflow. However, there are certain aspects that need to be kept in mind while opting for real-time 3D rendering.
