7 Stages Of 3D Interior Design Rendering

3D rendering for interior design made by a professional 3D visualization company is a perfect way to get atmospheric, photorealistic and accurate materials for presentations. Even the most difficult concepts and minute details are brought to life exactly the way the author wanted them to look. Every piece of furniture, important decor element, stunning visual trick and designer’s touch is replicated to the tee. How are these masterpieces created? Today we lift the curtain from residential 3D render creation process, using our recent 3D visualization for a Boston living room project as an example. Join us as we showcase 7 stages of every 3D interior rendering project in detail!

3D Rendering For Interior Design: 7 Stages

#1. Collecting References

Every 3D rendering for interior design project starts with gathering physical references: blueprints, sketches, props or photographs. Verbal explanations should be avoided, since it’s much more difficult to transfer words into 3D models. Thus interior rendering project speed and number of corrections depends a lot upon the materials 3D Artists get.

#2. Creating Foundation For A Scene

After the references are passed to 3D artists, they begin their work by creating the room from basic shapes: blank walls, floor and ceiling as well as guidelines for further object placement and textures. A single base light source is established, usually the “sun”. After the basic shapes are placed, more details are added: doors, windows, patterns, etc. The scene is set.

#3. Adding Furniture And Decor

But 3D rendering for interior design is not about blank space, it’s about the content. The empty room is then filled with 3D furniture and decor models, which are either chosen by the customer or custom-made from scratch. At first the objects are plain polygons, with definite shape but only a vague semblance of material visible. The items are carefully placed according to references. Contextual decor is not always chosen by clients, sometimes 3D artists choose it themselves, making sure that it matches the furniture and organically fits the composition.

#4. Adjusting Camera Angles

One of the biggest reasons to choose 3D interior rendering is the ability to pick any camera angle for the 3D visualization, and not be limited just to one or two. Remember, interior design renderings are whole spaces, not just separate shots, so it’s technically possible to show their every nook and cranny. But there is no need to do that for design presentations and promotional materials, 3-5 good POVs are more than enough.

#5. Adding More Light Sources And Editing Lighting, Shadows And Reflections

Realistic lighting is the thing that makes or breaks 3D rendering for interior design, so it’s vital to do it right. In real world there is never one source of light, unless we’re talking about some concrete box with one hole in it. Lamps, light fixtures, chandeliers – the list can go on, and all of them produce different types of lighting – and they all have to be accounted for. Finally, a 3D artist has to meticulously edit shadows and reflections to avoid uncanny valley and ruin a perfect shot.

#6. Testing The Render

After main stages of 3D rendering for interior design are done, the render needs testing. For that interior visualization software like 3DS Max runs various checks and specialists review the results. If glitches, clipping or lighting errors are detected, they are immediately fixed. This is by far the most important and time-consuming part of the process.

#7. Final Rendering

7 Stages Of 3D Interior Design Rendering: Post-Production

3D rendering for interior design is finished, everything is checked and there is nothing that can go wrong – which means it’s time for post-production and rasterization. Using graphical editors like Photoshop specialists retouch the image and add subtle effects like bloom and chromatic aberration. Voila – the set of gorgeous pictures is done and sent to the customer, all within 24 hours!

And there you have it – this is how 3D rendering for interior design is done. There is no magic behind this process but tremendous skills of 3D artists and hours of relentless hard work. Put together, these ingredients ensure the impeccable quality of the imagery so you get perfect marketing materials to present your design to customers.
