The process of creating 3D visualization in milestones looks similar for each project. It does not matter if we make the interior visualization, architectural (external) visualization or visualization of the product in the form of, for example, a packshot. In this text, I will focus on these three types of visualization.
I will try to make this text also a kind of a glossary of terms used by 3D graphic designers. So, let’s begin. I hope that I will be able to make this post reader-friendly.
You are welcome!
Conversation – determining needs
Contrary to appearances, the first stage in the process of creating 3D visualization is not modeling, lighting or rendering, it is not even post processing. It is a conversation with a client. Probably many of you now feel like closing the tab with this text, but wait, please. After all, in 90% of cases, visualization is performed for someone, for a certain recipient, with a certain purpose, which is the reason why the need for such a visualization is created and thus, this is the first stage that is the most important one.
At this stage, I always try to explore the needs of the other side, get to know what is this person’s concept of the graphic, which is to be used to promote the service, product or investment. After all, not everyone needs 100% photorealistic visualization with high specificity. I propose other solutions for a production company, and other for architects. It all depends on the time we have for the task and, of course, on the budget. After exchanging usually a dozen or so e-mails, or a few phone calls and setting a few details, we can move to the next stage.
Completing the source material
Indeed, we have not launched the 3D graphics program yet
The best source material is a project carried out in the CAD program, there is no doubt that on the basis of a detailed design, it is possible to make an exact model, which would later look beautiful as a render or ready visualization (I will explain what a render is later). Some of these programs even allow you to export a 3D model in a suitable format that can be directly imported. This does not mean that it is enough to take such a model, import and press “render” – I suppose that such a graphic would not satisfy anyone.
Another source material may be a sketch (indeed, a sketch on a piece of paper). It is very often the case that manufacturers do not carry out comprehensive documentation since it is not needed by anyone. I have performed many 3D models on the basis of sketches, although it is not a form as convenient as technical drawings, but it does not prevent the task from being completed.
Necessary information can be provided by a product. It transfers the real product into a virtual space of polygons, points and edges by means of a caliper, meter and other measuring instruments.
It is only in the third section that the program is turned on and we start creating 3D visualizations.
Modeling is nothing more than the process of creating a virtual model of a real object in a 1: 1 scale (3D programs have a system of units that makes it easier to maintain the ratios of the model). This stage is the most arduous and mechanical one.
Raw 3D model, wireframe.
The 3D model must have a defined material in order to look realistically. What are materials in the meaning of 3D graphics? To answer this question I have to use a few simplifications since no regular reader would be able to get through a boring explanation of what is the IOR, specular, bump map, etc. I’ll try to explain it simply.
The material defines what color the object should be (white, black, red) or what texture it should have (e.g. wood). In addition, we can determine bump mapping, which gives us the impression of a rough surface of the model (rocks, bricks). We can also determine whether it should be glossy or matte.
It’s nothing like retouching the final shot rendered by the program, we improve the image, contrast, color. Sometimes, additional elements of the photos or backgrounds are added.

What a relief! We managed to reach the end of the post about the process of creating 3D visualization. Thank you for your patience while reading and I hope I didn’t bore you too much.
I strongly encourage you to familiarize with the portfolio of our studio!
