What Is 3D Rendering And How Does It Work?

3D rendering is all around us. From huge action movies to car commercials to previews of upcoming buildings or product designs, 3D visualization has become so widespread and realistic that you probably don’t even know it’s there.

Technically 3D rendering is the process by which the three-dimensional (3D) reality is converted into a 2D visualization – a photograph or a realistic picture is just that. In design, however, 3D rendering is rather the process by which designers and architects visualize what they have in their heads. They put to paper or a screen their creative designs as close to reality as possible.

3D rendering in design may be done manually with the use of elaborate and highly skilled drawings. Today, more often, 3D design rendering is done by the use of some specialized software. Naraci offers powerful Interior Design Software options help to achieve 3D rendering much more easily, quickly and with much more realism.

The Future of 3D Rendering

The future of 3D rendering is starting to happen today with augmented reality (AR) and virtual reality (VR). Here 3D rendering is taken to the extreme and observers are immersed in the realistic image.

As 3D rendering goes forward, the technology is still growing. The initiators of the technology – the designers and architects, remain one of the most ardent users of 3D rendering (even with AR and VR), as it is the best way to visualize their ideas and their work. There is no end to the amazing things you can do with a high-quality render. If you’re looking for innovations for your business, 3D renders are the way to go.

How Does 3D Rendering Work?

Well, one might wonder why they need a computer or software to render an image.  In design and architecture, renders allow creative people to communicate their ideas in a clear and transparent way.

3D rendering software essentially allows a designer to bring their concepts to life within a digital image with excellent detail, and inexpensively compared to real-life prototyping of various scenarios. The client can see how the complete image of the house would look like from all angles. The image can include immaculate details of the home such as the lawn, parking, swimming pool, and garden.

The Major 3D Rendering Techniques

The main techniques used in 3D rendering are scanline, raytracing, and radiosity. All these techniques have their pros and cons, and it is best to make the best use of them in the right proportions.


When you need the speed is most important, this is the best option. It provides real-time rendering based on a polygon by polygon basis in 3D modeling instead of rendering using pixel by pixel.

Ray Tracing

Ray tracing is a technique tracks the exact number of ‘bounces’ of light off the product on a three-dimensional scale. This technique attempts to mimic real-world light properties using processes like diffusion, reflection, shallow depth of field, and soft shadows.


The radiosity method for computing the interreflection of light within diffuse environments is described.  It simulates the diffuse propagation of light starting at the light sources.
