A guide to 3D CGI and how it can help you

Table of Contents

CGI is the application of computer graphics used to design still or animated visual contents. What is the full form of CGI? CGI is the abbreviation for Computer-Generated Imagery. It has wide applicability in films, ad commercials, television programs, videos, and 3D images.

CGI is way cheaper than the physical way of creating miniatures, as it does not require extra resources. Plus, it is also not safe to shoot in remote locations and possible to create such visuals. CGI enables 3D image creation that is otherwise not possible to do using any other technology.

CGI is a young art form used to create 3D pictures, animation, and visual art. With CGI, anyone can create high-quality product images and graphics to make their products gain a 360 view. Not just that, artists can add extended realities and interactivity through AR and VR to offer next-gen consumer experiences.

The combo of CGI and 3D rendering is a great pick. It helps in creating 3-dimensional product imagery that is a perfect fit to boost your brand across digital and e-commerce platforms.

CGI can be used to create many such 3D models of buildings, cars, humans, and far-off locations. The created 3D models are then connected to a real-life scenario to build engaging products.



CGI is executed in various ways. It uses algorithms to build fractals that help create sophisticated visual patterns. The other methods include drawing in a 2D pixel-based image editor and designing shapes to create images.

CGI allows easy assembling of 3D shapes and images. It only takes seconds or minutes to render a single frame that results in the creation of naturalistic photos.

The 3D graphics are also put to use to create computer-generated images. It works by ray tracing or vector 3D graphics. Ray tracing influences the way light shades fall upon the surfaces making them extremely flexible.

While rasterized 3D exclusively deals in the real-time display of animated images. It uses polygons and other shapes to add superior textures that help in defining the color, surface texture, and glow of a 3D image.

With CGI, a single artist can produce content without any use of actors, costly set pieces, or props.



You might have seen a 3D rendered image in recent times. Well, it is quite popular in the digital world of today.

Whether you are gazing at animated caricatures, tossing magazine pages, or scrolling through social media on your smartphone, you are likely to see digital images designed by the process of 3D rendering. In reality, 3D rendered images have become a new norm of the visual content industry for content creators, marketers, and many others.

Although 3D rendered images have become a common part of your daily life, they are just simple images created with artistic skills and graphics software. Let’s dive in to see what 3D rendering is and how it works in the domain of advertising and marketing.

What is 3D rendering?

3D rendering is the method of creating an image relying on the three-dimensional data stored in a computer. It is basically a method of turning a 3D model into a 2D image to make it viewable for common people. It can be used to create an array of images, anything from unrealistic to photorealistic.

The 3D rendering undergoes so much detailing that most consumers are unable to spot a difference between a captured snap and a 3D rendered image. The process of designing a 3D rendering image starts with 3D modelling which we will look into in detail in the next section.

The initial days of 3D rendering were limited to a handful of big organizations with deep pockets and plenty of resources. Just think of the big-budget films like the Harry Potter series and Tron that was produced by big studios.

But, it is easily accessible in today’s times. Even the software and tools that were earlier missing to render a 3D image have improved a lot and are widely available now. Today, companies of any size can come up with 3D rendered images without spending any hefty amount. Let’s dig in a little more to see how a 3D rendering works.

How does a 3D rendering process work?

The 3D rendering involves a fusion of planning, software, and artistic skills. Just the right strategy is not enough, what you require is the blend of the right tools and experience to create an appealing product that talks to viewers.

Step 1: Working on The Client’s Vision

The first step is to understand the client’s expectations. A 3D artist looks for the plans, sketches, and reference images shared by the client. The artist then visualizes the project and envisages the camera angles for a 3D image.

Step 2: 3D Modelling

The artist creates a virtual model using 3D modelling software. The 3D modelling process undergoes an array of steps to come up with a 3D image.

  • Lighting: In this step, an artist uses software algorithms to reproduce natural lighting. The lighting effects are added within the 3D modelling software to amplify the image in all three dimensions. Lighting also helps to create a 3D image perception for 2D images.
  • Texturing: The software reads the surface texture that is already present in the 3D model. Well, it does so by tracking the light and colour variations present in it. Texturing plays a key role in the creation of a photorealistic 3D rendered image.

Step 3: Rendering

Rendering is the actual process of image creation. What 3D modelling software does is convert a model into a high-resolution image. It then applies to plenty of visual content.

Step 4: Refining

The final process of a 3D image development is high-quality editing. The editing undergoes lighting, texturing, and various other editing programs to deliver a polished image. The 3D artists arduously work on the images to fine-tune the appearance of the image that matches well with the client’s expectations.

After the final rendering of the image has been refined and completed, it can then be applied across applications of the client’s choice.

How Much Time 3D Rendering Take?

The time taken to render a 3D image depends on the context and the starting point. Let’s go through some examples to understand it.

Example 1: 3D rendered images for a product catalogue

Suppose, a B2C brand wants to expand its e-commerce photography. Well, it is possible to create natural images for its entire catalog with the use of rendering software.

A brand can create a million high-resolution images in a week. The brand then replaces the traditional product photos with these 3D images. 3D rendering is way faster than traditional product photography.

Example 2: 3D rendered images for product customization

A 3D rendering application also allows shoppers to view product customizations in real-time while shopping on your website. With an interactive 3D application, it is quite possible to develop 3D renderings in real-time.

For instance, a shopper can make color changes and view extra features instantly.

Example 3: Start fresh to create 3D rendered images

Both of the above examples considered the 3D product file to be ready with you.

When you start from scratch, the process of creating a rendering will take time. Developing a basic model takes time on which a 3D image is created.



3D modeling is all about creating a 3D illustration of any object or a surface by exploiting simple shapes, polygons, and edges in simulated 3D software. Well, you can see all of that in current movies, animations, and the unstoppable video games teens are crazy about.

Based on the modeling format, real-life objects are fed into 3D software through a 3D-scanning device. You can then create a final 3D model using these digital objects. After that, you can exploit these objects the way you want to use them.

3D Modelling Uses

Let’s look at a few industries where 3D modeling finds its use extensively.

  • TV/Films – 3D modeling is the key to create CGI characters, objects, animations, and creative titling for movies and commercials.
  • Video Game Development – It helps create the whole 3D elements of video games. These video elements are pretty much the same as the animations being used in any film or TV commercial.
  • Architecture – The 3D CAD models are a great help to create real-life fabrics. A 3D modeling can build engaging renderings of buildings and structures.
  • Engineering – It comes with various techniques to create designs and models to ensure engineering masterpieces. The 3D way of doing things has replaced manual fabrication and offered a quicker solution to build things.

How Does 3D Modeling work?

A 3D artist starts by creating some primitive shapes like a cube, or a plane. Well, it’s just a start to modeling.

The artist creates a basic form and then exploits the basic forms with the help of modeling tools. To get started, it’s always better to make simple forms and then head for complex forms and shapes.

3D modeling is all about following an outline to place the individual vertices to get the right contours for a specific object.

The mesh exteriors comprise polygons that can be divided into short forms to design more details. These small forms play a key role to create a 3D animation.

When creating delicate models like creating a character’s knee or elbow bends, it needs extra polygons to establish dynamic motion.

Well, various tools help you hasten your modeling process. All such programs have a mirroring technique that aids an artist to create a symmetrical model. You can create such well-formed designs by working on even a quarter part of the object.

It offers great help to design creative characters. What an artist need is to work on one side of the character and the 3D software aligns the desired axis on the second half to create a perfect model.

This way an artist can create an appealing model, they can even design more complex models than it is. These kinds of techniques come to great help for creating complex video games.

A Look into 3D Modelling Softwares You Must Have

3D modeling software offers wings to an artist to create 3D objects and design characters. The tools are an inescapable way to pour your creative art into adding realistic details to your designs. Here is some 3D modeling software in high use among 3D artists.

  • AutoCAD: AutoCAD is into the 3D world way before people came to know about it. The commercial software was released in 1982 and designers reckon it as the gold standard of 3D designing. It is available for Windows and macOS users.
  • ZBrush: ZBrush displays clay sculpting tools into practice and is very much there in its pro-level software. The process does take hours to execute and is not a great fit for newbies. Sculptris also comes from the same bunch of developers, which is similar but more of a simple choice to make.
  • SketchUp: SketchUp offers a 3D program for designers having basic know-how of 3D modeling. The tool helps to create architectural structures and is even used to visualize interior designs, engineering, construction, and urban planning.
Model to CGI


Photorealistic rendering is the magical realm of transforming a crude image into a real-life photograph. Well, it is a branch of 3D rendering to create a final image that is hard to differentiate from reality.

These images find extensive use in the domain of architecture and interior design. It creates basic know-how of how a project will look like at its final stages.

Photorealistic renderings also channelize real estate marketing to build an emotional connection between the client and the property, even before its construction.

Furniture catalogues also use photorealistic rendered images to put up furniture in real life setup. That too, with no need for physical setups.

They come to great help even into product design and prototypes along with a wide variety of areas.

Steps to create a Photorealistic 3D image

#1 3D Modelling: 

It starts with creating an object’s geometry predefined measurements. We have plenty of tools to design 3D models such as Google SketchUp, ZBrush, and a few more. If you want a free tool, try your hands out of Blender.

#2 recreating physical attributes using materials to design realistic images

The tools already come with materials in all colours and surfaces. These surfaces and objects you work to reflect and absorb light. So, it is important to tune up a few traits like transparency, object texture, and a few more.

#3 picking up light sources

The lighting has a key impact on your model object. It can be both artificial and natural. For an artist, choosing the brightness and depth of light matters the most in creating a real object. Even the shadow work plays a significant role to design a dynamic 3D model.

#4 ideal placement of virtual cameras

For a 3D artist, placing the virtual cameras keeping the right angles in mind is very important.

#5 rendering

3D rendering or portraying the image onto a 2D surface is a key part of 3D modelling. PRMan, Corona Render, Maxwell Render are some popular rendering tools in wide use among artists.

#6 adding special effects

Processing of handy images by the use of special effects tools like Adobe After Effects Pro, Adobe Photoshop, Adobe Premiere Pro. An artist can explore wide horizons of artwork by feeding special effects like surroundings, extra shades & effects to create atmospheric images.

You can pour your vision onto 3D digital software to create something meaningful either for yourself or your clients or even your personal business.

A 3D model can even be reused after its final construction. This has made possible the availability of ready-made models into the market. Now. Designers can pick such models as per their project needs and lower their overall expenses.

Benefits of Photorealistic renderings

These images offer plenty of benefits to a wide audience looking to scale their businesses, enhance their personal profile, and create unimaginable stuff.

  • Help developers and real estate agencies sell their products

Developers and realtors are leaving no stone unturned to connect better with their target audience. They are using content marketing (blogs & social channels) to create brand awareness, engage with their audience, raise their brand reputation, and boost their sales.

There are ample ways to do that.. Photorealistic rendering is one of them. It is a great way to make your brand stand out from your rivals.

It does the most important job for real estate developers and realtors. That is building an emotional connection with people.

The only thing they need to take care of is producing a refined image to maximize their marketing goals. As a realtor, you can even test the market before construction to check if people are actually interested in buying something that you are willing to offer.

  • Allow architects and designers to make an impact

As a designer, you would spend a lot of time preparing a project for an architectural bout. So, why not give your best to it?

The best sane advice we would give is to heed the visual quality of your proposal.

Imagine the jury being shown plenty of project boards. Now, which one do you think will excite them? The project board with amazing visuals. Isn’t it!

Before submitting your project, make sure that your project boards create an instant connection with the jury and stand out from the rest.

Not every idea demands quality visuals. Quite often, you only need to have a visualization of how space would look after it’s built. So, it’s enough to create a basic 3D model in the design phase.
