3D Modeling vs Rendering: The Ultimate Comparison

3D modeling and 3D rendering bring an object a more realistic look. The question is, “3D modeling vs rendering, what are the differences?” It is easy to answer when looking at their output: 3D modeling gives real 3D objects while 3D rendering creates 3-dimension 2D images. The other elements separating these terms include the usage, technique (software), and process. Through this article, let’s look at the similarities and differences between 3D modeling and 3D rendering.

What is 3D Modeling?

What is 3D Modeling

3D Modeling is the process of designing and producing to create a three-dimensional representation of any object or surface. It stimulates a real or virtual reality object’s polygons, edges, and vertices. 

3D modeling often appears in video games and movies. You can also easily capture 3D physical models in architectural visualizations, real estate, product design, medical diagnostics and treatment, video games, etc.

What is 3D Rendering?

What is 3D Rendering

3D rendering is a process of transferring an available 3D object, model, or scene into a 2D image. Length, width, and height are proportional to the actual size to give the most realistic look.

These 2D images are beneficial for presentations, illustrations of interior designs, product designs, entertainment, etc. You don’t have to bring a real model to show and persuade your customers.

3D Modeling vs Rendering: The Similarities

3D modeling vs 3D rendering have some same features and requirements. So, what are they?

  • Computers are must-have equipment: They are both created on a computer. Although the results are dissimilar, the processes require specific software.
  • High requirement: Producing 3D models and 3D images is not as easy as squeezing clay. Each object or surface has specific features, materials, and details. Engineers who don’t know or skip cannot make it realistic. Besides, success often doesn’t come on the first few attempts. They have to try and try again to accumulate experience. Engineers should be high-education, high-attention to detail, and patient.
  • Engineers should be good at making decisions: After analyzing tasks, they have to design the correct dimensions, colors, lighting, and materials for the blueprint.


Can you start rendering without 3D models?

You can only start rendering with 3D models. The mission of 3D rendering is transforming a 3D model into a true-to-life and easy-to-imagine image. All the ideas of rendering are from 3D models.

Does 3D modeling require coding?

You don’t need to have coding skills to practice 3D modeling. To become a 3D modeling master, you should have strong 3D knowledge and be fluent in using software and techniques.


To sum up, 3D rendering comes after 3D modeling in a process. Each stage requires different software, techniques, time, and effort. The outputs can be used for many purposes, including marketing, business, or entertainment. 3D modeling vs rendering is complementary to help you achieve the best performance.
