What is 3D Rendering Used For?

We are surrounded by CG images all day long. They come in all shapes and sizes–from advertisements to social media posts or even cartoons on TV. The way these pictures appear can be astonishingly different; some have a depth that makes them feel almost lifelike while others seem flat despite being three-dimensional. Why are these everywhere? It’s simply because leading professionals in every field recognize the value of 3D rendering in all its varied uses.

What is 3d Modeling and Rendering?

Visual marketing has taken the world by storm. The process of creating these images can be divided into two broad categories: 3D modeling and 3D rendering.

3D Modeling

3D modeling is the process of creating three-dimensional objects on a computer. There are a number of techniques for creating 3D models. Some people start with a simple three-dimensional object (sometimes called a “primitive”) like a cube or sphere and extrude or deform it to create the desired shape. Others use polygonal modeling, where objects are built up from smaller faces.

3D rendering

Where 3D modeling defines the mass, or shape of the object, 3D rendering is concerned with properly depicting it graphically. To accomplish this, the designer will add texture to the objects, add lights to the scene, and instruct the rendering software on which techniques should be used in calculating the final image.

What are the Best 3D Rendering Examples?

3D rendering is an essential part of our everyday life. It can be used in a variety of fields to boost business and people’s lives, which makes it popular among many professionals today. Here are just a few:

  • Architectural and Building Design
  • CGI (Computer Graphic Imagery) in Movies
  • Medical Imaging
  • Staff Safety Training
  • Environment and Driving Simulations
  • Product Modeling and Prototyping
  • Civil and Structural Engineering
  • 3D Video Games

How You Can Learn 3d Rendering Free

3D Rendering is used everywhere these days. And now, VR (virtual reality) and AR (augmented reality) are adding to the need for qualified technicians. And this is a great time to learn! There are many affordable options such as Lynda, Udemy, and Pluralsight. There are free ones as well. YouTube is a great option for getting started or for learning tips about a particular skill. In addition, look into online forums to get your questions answered.

On the software side of things, SketchUp and Blender are great places to start. Both are very capable 3D modeling programs, and each has free options. There are rendering options in these programs, though you’ll likely want to research add-on render engines at some point. Cycles is a very popular engine for Blender, and it’s free. For SketchUp, there are many great renderers available as plugins, including Twilight Render (also free).

As you can see, learning 3D rendering doesn’t have to be expensive. And with the current demand for these skills, it’s a great time to get started. So what are you waiting for? Start learning today!


Hopefully, even in this short overview, you have seen a bit of what 3D rendering is and what it is used for. There are many applications for it in a variety of fields, and the demand for qualified professionals is high.
