3D rendering is a powerful tool used to capture 3D scene information from a particular viewpoint through the assistance of a computer. The scene can then be used to create a photo-realistic image that can then be used for multiple scenarios. 3D rendering has become an increasingly popular tool with architects, event planners, and marketers.

In this article, we discuss the process of 3D rendering helping you get a better understanding of how 3D rendering works, and how it can help your business.

1.   Understanding the Client’s vision

The first step in the 3D rendering process is understanding the purpose and vision of the project. Many 3D rendering businesses will sit down with their clients and listen to their story to reach a better understanding of their needs and goals.

2.   Analyze and Design the Project

The second step is to analyze and design the project. This step requires the 3D render artist to work with the client to determine which aspects of the project should be highlighted and from which viewpoint. The chosen feature points of the project will influence the camera angle, ensuring project design meets the client’s goals.

For example, an event planner is wanting to see how many tables they can accommodate in an event space. The 3D render artist will likely decide that an overview of the event space from above will provide the best viewing angle for their client.

3.   3D modelling

The 3D render artist will then begin to use computer-assisted software to generate a 3D model of the project. The use of geometric shapes will be used to create an outline of the project in its most basic form, digitally. This is referred to as a “sketch,” as the 3D model can be altered easily to fit the client’s needs.

4.   Materials and Texturing

Once the 3D modelling “sketch”” is completed, the 3D render artist can add materials and texture to create a photorealistic image. The process involves adding images to the 3D model to make the model appear as realistic as possible; just as you would glue photographs to a collage or paint a model. This step can add a matte or glossy finish to each material, a soft or rough texture, adding color and dimension to the 3D model.

5.   Lighting

Lighting, shadows, angles, and reflections are added to create a hyper realistic model that represents real-world lighting. Just as a photographer manipulates lighting to create a desired effect, a 3D render artist will use lighting to create ambience or desired look of the 3D model.  This step requires creativity, research, and consideration to create a seamless look.

6.   3D Rendering

Depending on the complexity and desired end-quality of the project, this step is the most complex – it can take anywhere from a few moments to several days. Computer software is then used to sculpt the 3D render through multiple techniques, bringing the project to life.

7.   Refining

Refining the final 3D render will consider the client’s feedback and suggestions. Ultimately, the 3D render must suit the client’s needs, ensuring that the final project meets their goals and expectations. Once the feedback has been received and implemented into the 3D render, the artist will then add the final touches and details. This process refines the final project, adding high-end finishes and details to create the final masterpiece.

8.   Final Delivery

Once all the final details are in place, the 3D artist will hand over the final project to the client. The prior agreed-upon 2D images of the project will be sent to the client in the preferred format. The image file type will be given dependent on the needs of the client, either for web or print.
