Imaging a project in 3D: the steps

Imaging a project in 3D: the key steps

Reading time : 5 minutes

Visualizing a project in 3D means giving shape to an idea, evolving it from an abstract concept to a concrete visualization. This process relies on several essential steps, from the initial 3D modeling to the final 3D renderings. Today, 3D visualization companies such as GOCAM 3D™ produce high-quality 3D renderings that allow architects, designers, contractors, engineers, and inventors to accurately visualize their buildings, products, or inventions before the project physically comes to life in the real world.

1. Project definition and specifications

It all starts with an idea, a sketch, plans, and measurements. This could be a building, a product, or a design object. The idea is then structured and framed through a precise specification document: What is the final use? (print, web) What presentation style is desired? How many 3D visuals are needed? What are the technical constraints? What deadlines must GOCAM 3D™ meet to deliver the outputs? This preliminary and exploratory step is fundamental, as it guides and sets the direction for the entire production process up to the delivery of the realistic 3D renderings.

2. Collection of technical information

Before starting the production process of a project or a 3D product, GOCAM 3D™ first collects information such as plans, elevations, technical drawings, sketches, materials, and finishes. In cases where this information is unavailable, manual sketches are often created, with annotations, colors, and their placement. Next, the desired viewing angles are established. This crucial information sets the 3D artistic direction of the project, establishes the initial presentation and finishing guidelines, and defines proportions. Once these guidelines are set, production of the first 3D visuals can begin.

3. 3D modeling

3D modeling is the heart of the process. It is at this stage that GOCAM 3D™ brings objects, structures, and products to life virtually, crafted by experienced 3D artists. Using specialized software (such as Maya, 3ds Max, SketchUp, Rhino, SolidWorks), 3D models are created to scale and with high fidelity, preparing them for visualization. Once the 3D models are completed, the first validation 3D visuals are sent to the client to approve the shapes. At this stage, the 3D images are representations without textures or lighting and are a skeleton of the project or product. This forms the essential foundation for generating realistic 3D renderings.

4. Applying materials and adding textures

It is at this stage that GOCAM 3D™ 3D artists apply textures and materials to the previously created 3D models. Wood, glass, metal, fabrics, each surface is carefully treated to react to light as it would in reality. This is where the first 3D visuals take shape, and realistic 3D renderings can be generated. Using 3D rendering engines such as V-Ray, Arnold, Corona, or Lumion, we achieve 3D renderings with striking realism.

5. Lighting, composition, and framing

Lighting plays a crucial role in the quality of 3D renderings. The experienced 3D artists at GOCAM 3D™ carefully configure each light source to simulate natural or artificial lighting. Optimal camera angles are chosen to compose the 3D visuals as a photographer would. These settings greatly influence the realistic 3D renderings, which should look like a photograph rather than a virtual simulation.

6. Intermediate 3D renderings

Before reaching the final versions, the 3D artists at GOCAM 3D™ generate a second set of 3D renderings to validate everything with the client. These tests allow verification of proportions, colors, lighting, materials, and the composition of the 3D visuals. At this stage, back-and-forth adjustments between modeling, lighting, textures, and materials are frequent. GOCAM 3D™ fine-tunes everything until achieving realistic 3D renderings that exceed the client’s expectations.

7. Postproduction and retouching

Once the realistic 3D renderings are produced, all 3D visuals go through a postproduction phase. Using software such as Photoshop or After Effects, the 3D artists at GOCAM 3D™ retouch colors, add visual effects, or integrate the 3D models into a real environment by overlaying a photo onto the 3D visual. This step further enhances realism and produces stunning realistic 3D renderings, which can now be used online or printed for presentation to clients, partners, or investors.

8. The first project presentation

The realistic 3D renderings produced are used to sell an idea, convince an investor, get a project approved by the city and planning council, obtain a building permit, or launch a marketing campaign. Realistic 3D renderings allow the target audience to fully immerse themselves in the project. A well-executed 3D visual evokes emotion and supports decision-making.

9. Subsequent modifications and project maturity

A project is never truly complete. Clients of GOCAM 3D™ often get back in touch to request additional views or make minor changes once the project is delivered and the final 3D renderings are provided. Based on feedback, modeling can be adjusted, textures modified, or 3D renderings redone. This ability to iterate quickly using realistic 3D renderings is a major advantage during development phases.

10. Creating 3D animations and 3D videos

Some projects by GOCAM 3D™ go beyond realistic 3D renderings. We can create 3D animations, 360° 3D videos, 3D videos, and 3D virtual tours. The 3D visuals come to life, and these deliverables take less time to produce since the sets, objects, and buildings are already modeled and ready to be rendered again. These technologies, which are still based on the same foundations of 3D renderings, greatly expand presentation possibilities.
