WHAT IS 3D RENDERING?
Definition.
Put simply, 3D rendering, also known as image processing or CGI rendering, is the use of computer rendering programs to create CGI (computer-generated imagery). These images can be photorealistic or non-photorealistic. It is a creative process where 3D artists use computer graphics to convert 3D models into images. These images can be used for many reasons, mostly as marketing assets for advertising campaigns. They may include photorealistic or non-photorealistic images. It is the final process of creating the actual 2D image or animation, which may be used for various things, from conceptualisation to marketing.
In comparison, you can get the same results as taking a picture or video in real life. The difference is that the output will be created digitally. It is a powerful tool with more flexibility than professional photography or videography.
THE HISTORY OF 3D
History.
The history of 3D CGI rendering is a fascinating journey with significant advancements. Here’s a brief overview of the history of 3D:
Early beginnings (1960s – 1970s)
People started making 3D graphics when computers began. They were testing basic 3D images on big computers. They made simple wireframe models back then.
Introduction of ray tracing (1980s)
In the 1980s, there was a big step forward in 3D graphics. They started using ray tracing, which made lighting and shading look more authentic. But it needed a lot of computer power and was used primarily for science and research.
Emergence of 3D graphics cards (1990s)
The 1990s marked a turning point with the emergence of dedicated 3D graphics cards. Companies like NVIDIA and ATI (now part of AMD) began producing graphics hardware that accelerated 3D rendering, making it accessible to consumers and gaming enthusiasts.
The rise of 3D animation (late 1990s – early 2000s)
The late 1990s and early 2000s witnessed a boom in 3D animation in movies and video games. Pixar’s “Toy Story” in 1995 was a ground breaking example of computer-generated 3D animation.
GPU advancements (2000s – present)
As Graphics Processing Units (GPUs) improved, they made it possible to show 3D images instantly in video games and interactive stuff. This time also saw more use of 3D in things like designing buildings, products, and virtual reality.
Global impact (present)
Nowadays, 3D render service is vital in many industries like entertainment, advertising, architecture, and healthcare. It helps show and explain tricky ideas and designs.
Ray tracing renaissance (present)
Since hardware-accelerated ray tracing came along for GPUs, it became popular even though it used to need lots of computer power. Now, we get more real-looking and superb 3D graphics because of it.
At XO3D, we’re thrilled to be part of this always-changing field. We use the newest tech and methods to make fantastic 3D pictures for businesses. The story of 3D graphics shows how we’re always trying to make things look more accurate and better with computers.

WHAT TYPES OF FILES ARE NEEDED?
Examples.
To kickstart a project, you’ll need specific types of files that provide the necessary information for our team at XO3D to work on your project effectively. Here are the key file types that may be required:
3D model files
These are the core of any 3D rendering project. Although model files can be built by the 3D rendering firm having your CAD model ready is a great help to begin the project. Common 3D model file formats include:
OBJ: A versatile and widely used format.
FBX: Used for 3D models and animations, especially in the gaming industry.
STL: Often used for 3D printing projects.
3DS: Commonly used in older 3D modeling software.
BLEND: Specifically for Blender software.
Texture maps
These files provide details like colour, texture, and surface characteristics for your 3D model. These files do not need to be supplied by the client and are sourced by the 3D rendering company. These are used to make photorealistic renderings. Common texture map file types include:
JPG: For standard images.
PNG: Supports transparency and is commonly used for textures.
TGA: Offers high-quality image data.
Reference images
Providing reference images or concept art that showcases the desired look and feel of the final render can be immensely helpful.
Scene files
If your project involves complex scenes with multiple objects, lights, and camera setups, scene files specific to your 3D software (e.g., .BLEND, .MAX, .MA) can be essential.
CAD files (if applicable)
For architectural or product rendering, Computer-Aided Design (CAD) files in formats like .DWG or .STEP may be required as a basis for creating 3D models.
Animation files (if applicable)
If your project involves animations, you’ll need animation files in formats like .FBX, .DAE, or others, depending on your software and requirements.
Material descriptions
Detailed information about the materials and their properties can be helpful. This might include specifications for textures, roughness, reflectivity, and more.
Although none of these are essential to begin a project, providing these files allows us at XO3D to understand your project’s scope and requirements, ensuring we can create the stunning 3D renders you envision. Additionally, clear communication about your project goals and any specific preferences will further enhance the quality of the final results.
HOW LONG DOES A 3D RENDERING PROJECT TAKE?
Process.
The duration of a 3D project can vary significantly depending on several factors. At XO3D, we strive to provide efficient and high-quality rendering services. However, the timeline for a project can be influenced by the following key factors:
Here’s a rough idea: a simple project with just one thing to show might take a few days to a week. But it could take weeks or even months if it’s more complicated with many scenes, animations, or detailed models.
For a precise estimate, it’s best to talk to the 3D render service you’ve chosen. Please share all the details about your project, what you need, and when you need it. Then, they can give you a timeline that precisely fits your needs.

How long does 3D rendering take?
Usually images can be turned around in less than a week. Images can be done in 24 hours, depending on the project size it could take longer.
What is a photorealistic rendering?
A photorealistic rendering is a 3D rendering that is life like. It is a style of 3D rendering that allows clients to have a image that looks as good or better than a camera could take. Photorealistic images are created from 3D models.
What is a 3D image render?
A 3D image render is a digital picture created by software to look like a realistic or stylized scene or object. The process starts with building a 3D model, adding materials and textures, and setting up lights and camera angles. Render engines like V-Ray, Blender’s Cycles, or Arnold then calculate how light interacts with the surfaces, creating effects like reflections and shadows to make the image look lifelike. This technique is used in many areas, from architectural and product visualization to character design and animations, allowing artists to produce visually impressive, detailed images.
