What is 3D Rendering? General Introduction 

What does 3D rendering mean? 3D product rendering is a method of digital design that has undergone refinement in tune with rapidly advancing technologies. Let’s answer the most commonly asked questions regarding the basics of 3D rendering. 

  • Question 1: What is 3D rendering? 

To fully understand what 3D rendering is used for, we need to start from a more general concept – 3D visualization.

  • 3D visualization vs 3D rendering 

3D rendering is simply one of the last stages of 3D visualization. The entire process constitutes different phases of progress. Let’s go into more detail.

What is 3D visualization? It’s a combination of skills employed for a product demonstration. It’s a multidisciplinary procedure involving concept, modeling, materials, lighting, rendering, refinement and delivery. 

The practice creates a realistic form of a specific visual task to provide a clear digital representation of what your product will look like in real life.

What is the definition of 3D rendering? It’s one of the last stages of 3D visualization. It’s the process of generating detailed and lifelike images from a digital 3D model. 

With the use of advanced illustration software, the designer is able to create a realistic image that can even be superimposed into a digital representation of an actual location.

  • 3D rendering vs 3D modeling

What is 3D modeling? It’s the process of developing a mathematical representation of any object in 3D via specialized software. It’s an indispensable phase for rendering 3D objects in finer detail. 

How does 3D modeling work? A graphic designer uses special software to manage points corresponding to a specific design in a virtual space. As a result, an object is created.

Digital 3D models are presented to clients to show the dimensions of the product before it moves on to the rendering and fabrication phase.

Below, you’ll find a basic comparison for “what is 3D modeling and rendering to comprehend what 3D modeling is used for as opposed to 3D rendering

  • Modeling prepares for rendering; rendering prepares for production.
  • Modeling gives an overall demonstration of a digital 3D object;  rendering shows it with more realistic details.  
  • Modeling helps with the arrangement of hazardous features; rendering shows detailed properties like colors of the object for clients.
  • Modeling identifies general structural issues; rendering depicts 3D images of objects through virtual tours and walk-throughs. 

The above-mentioned points describe the main difference between 3D modeling and 3D rendering where one produces general objects and the other creates a realistic representation of them, respectively.

  • Question 2. How does 3D rendering work? The basic phases

For better application in your industry, a full understanding of how 3D rendering works is critical. Here are a series of phases that are integral for 3D rendering applications.

Phase 1: Understanding the project

The first stage is getting an accurate idea of what’s on your client’s mind. If the product is business signage, for example, you should collect as many details as possible concerning the sign’s dimensions, typeface, colors, shades, location, etc. 

Phase 2: Diving into 3D modeling

As mentioned above, this technique is used to manipulate vertices in virtual space. Created either automatically or manually, 3D modeling produces a digital mock-up of any given object. 

The essential part here is the collection of points in space that are mapped into a three-dimensional grid. All these points have their own positions, and after being placed in those positions, the surface of the product is produced.

Phase 3: Choosing the most representative materials

Creating a life-like rendering relies on accurately depicting the kind of material that will be used. The graphic designer modifies the material settings and appearance, like matte or glossy acrylic, to get a realistic visual representation. 

Other parameters are modified as well, such as the roughness of a given surface or even the hardware used to install it. 

Phase 4: Considering lighting for the right application  

Lights are essential for creating three-dimensional scenes in virtual space. To reproduce true to life lighting, the 3D artist includes digital “lights” in this stage of the illustration process. The software’s light settings aim to recreate the effects of light rays as they bounce off objects in real life.

Phase 5: Rendering a 3D object

After all the previous steps are completed, the rendering process enters into phase. It consists of creating naturalistic 2D images of the 3D object, similar to the method of taking photos in the real world.

Depending on the complexity and specifications of the scene being digitally reproduced, this process can last from seconds to days. Rendering can only be accomplished with the help of highly technical computer software.

Phase 6: Proceeding to the refinement phase

In this stage, the artist provides a digital draft of the rendering to the client, expecting corresponding feedback. After getting comments and suggestions, the artist implements the final changes for the end result. 

Phase 7: Delivering the final result

The client gets the images of the final product as agreed. The images are usually high-resolution with specific characteristics and scales included. This helps the customer determine whether they want to move on to the production phase.
