Introduction to what is a real time rendering
Real-time rendering has become increasingly important in various industries, from video games and virtual reality to film and architecture. Essentially, real-time rendering involves generating visual images on the fly, allowing for dynamic and interactive user experiences. This can be done through the use of specialized software and hardware, including graphics processing units (GPUs) and game engines. In this article, we'll explore what real-time rendering is, how it works, and its applications across different fields.
What does it mean to render in real time?
Rendered in real-time means generating visual images or animations on the fly, allowing for dynamic and interactive user experiences. This is in contrast to pre-rendering, which involves generating images (computer graphics) or 3D animations ahead of time and playing them back later. Real-time 3D rendering is used in a wide range of applications, from video games and virtual reality to film and architecture. It involves using specialized software and hardware, such as graphics processing units (GPUs) and game engines, to handle the complex calculations involved in generating high-quality 3D graphics in a matter of milliseconds. The goal of real-time 3D rendering is to create the illusion of a seamless, responsive environment that reacts to user input in real-time.
Real-time rendering basics
At its core, real-time 3D rendering involves generating high-quality graphics in a matter of milliseconds. This can be done through a combination of techniques such as ray tracing, rasterization, and shading. A powerful GPU is typically required to handle the complex calculations involved in real-time rendering. In addition, specialized software such as game engines (e.g. Unity, Unreal Engine) can provide a framework for real-time rendering in various applications.
Why ray tracing in real time?
Ray tracing in real time is becoming increasingly popular in the field of real-time 3d visualizations because it offers several benefits over traditional rendering techniques.
First, ray tracing is capable of producing highly realistic and accurate lighting and shadows in real-time, which can greatly enhance the visual quality of a scene. Traditional rendering techniques such as rasterization use simpler approximations to simulate lighting, which can result in less accurate and less visually appealing results.
Second, ray tracing can also improve the efficiency of rendering, as it can be used to reduce the number of calculations needed to generate an image. This is because ray tracing can more accurately simulate the way light interacts with objects in a scene, allowing the rendering engine to make better use of available resources.
Finally, ray tracing can also help to simplify the rendering pipeline, as it can be used to replace multiple traditional rendering techniques (such as shadow mapping and environment mapping) with a single, more accurate approach.
While the use of ray tracing in real-time graphics is still relatively new and requires specialized hardware and software, it is expected to become more widespread as technology continues to advance.
Which interactive experiences in real time visualizations?
Real-time visualizations can be used to create interactive experiences that allow users to explore and interact with a design in real-time. Here are some examples of interactive experiences that can be created using real-time visualizations:

Real-time rendering in video games
Video games have been at the forefront of real-time rendering technology for decades. It's what allows players to move around and interact with virtual environments in real-time, with the graphics adjusting and updating as they do so. Over the years, game developers have used various real-time render techniques such as shadow mapping, environment mapping, and global illumination to create more immersive and realistic game worlds.
Real-time graphics in virtual and augmented reality
Real-time rendering is not only important for creating stunning visualizations, but it is also essential for creating immersive virtual and augmented reality experiences. In virtual reality (VR), the user's movements and actions need to be tracked in real-time, with the graphics adapting accordingly to create a sense of presence and immersion. Real-time rendering is what makes this possible by providing instantaneous updates and adjustments to the virtual environment, making the user feel like they are really there.
Similarly, in augmented reality (AR), real-time rendered images can be used to overlay virtual objects onto the real world in a seamless way, creating a mixed reality experience. This requires fast and efficient rendering capabilities to ensure that the virtual objects are aligned and scaled correctly in relation to the real world. With the help of real-time rendering technology, developers can create immersive and engaging AR experiences that blur the lines between the real and virtual worlds.
Real-time images in film and animation
Real-time rendering is also becoming an increasingly popular tool for filmmakers and animators. By using real-time images, filmmakers and animators can preview their work quickly and efficiently, allowing them to make changes and adjustments in real-time. This saves both time and money, as traditional rendering methods can be slow and expensive.
Real-time images can also be used to create stunning special effects and animations in films and television shows. For example, real-time rendering can be used to create realistic explosions, fire, and other complex effects that would be difficult or impossible to achieve using traditional methods. This allows filmmakers to create more immersive and engaging content that keeps viewers on the edge of their seats.
In addition, real-time rendering is also being used to create real-time animations and interactive experiences. This allows viewers to interact with virtual characters and environments in real-time, creating a more engaging and memorable experience. With the help of real-time rendering, animators and filmmakers can push the boundaries of what is possible in film and animation, creating stunning visual content that captivates and entertains audiences.
Real-time rendering in architecture and interior design
Real-time rendering is becoming an increasingly important tool for architects and interior designers. By using real-time rendering technology, designers can create highly realistic and detailed 3D visualizations of architectural structures and interior spaces, allowing them to explore different design options and communicate their ideas more effectively to clients and stakeholders.
Real-time rendering can also help architects and interior designers to streamline their design processes, as it allows for quick and efficient changes and updates to be made in real-time. This saves time and money, as designers can quickly iterate on their designs and make adjustments as needed.
In addition, real-time rendering can help to enhance the overall client experience. With the help of real-time rendered visualizations, clients can get a better sense of how a space will look and feel, allowing them to make more informed decisions about the design. This can lead to higher levels of client satisfaction and increased business for architects and interior designers.
