Real-time rendering in future 3D games

Updated: Sep 22

Creating an image from three-dimensional data stored on your computer is known as 3D rendering. It is also considered a creative process, similar to photography or cinematography because it uses light to create images.



Market research shows how quickly interest in real-time 3D is growing. The 3D rendering market was worth $1.5 billion in 2018, but it is expected to grow to $6 billion by 2025.

Furthermore, if you've ever had to look at a 2D drawing and visualise a 3D product, you understand how difficult it is. Real-time 3D allows viewers to see and interact with 3D images or scenes that appear to move in real-time, such as in video games.


Computers work in real-time 3D rendering to photo-realistically convert 3D models into 2D images. Real-time 3D allows viewers to see and interact with 3D images or scenes that appear to move in real-time, such as in video games. Real-time 3D imaging simplifies everything by placing designs in their final locations.


However, rendering is the process of creating an image from your 3D scene in a 3D software package (Maya, 3Ds Max, Unreal Engine etc.). When you render a scene, the computer calculates the shading (reflections, diffuse, speculate, transparency, refraction, etc.) and lighting (light, shadows, etc.) to produce a 2D image or set of images that can now be viewed independently of 3D software.


The primary goal is to achieve the highest level of photorealism possible while maintaining an acceptable minimum rendering speed, which is typically 24 frames/sec. That's all the human eye needs to create the illusion of movement. Even though rendering is based on a wide range of complex calculations, modern software can provide some relatively simple parameters for you to understand and work with. A rendering engine is typically included in a modern 3D game engine and can produce truly stunning graphics.
