The beauty of 3D Modeling & Rendering

Nowadays technology went far enough and people are now able to model and simulate anything through their computers. Inevitably, we use 3D modeling & Rendering as the main tool for validating our design ideas. Without further delay, let me explain, how exactly it works.

Geometry of the scene is ready

First of all, when we have the final layout of the space we start building the geometry of the scene. Fortunately, we have wide libraries of furniture and decoration items. Occasionally, though some individual solutions have to be modeled from scratch, through polygon or spline modeling.

Subsequently, once the geometry is done, including the textile and all the tiny details we proceed to set the lighting in the scene.

Regardless, whether it is a studio rendering, interior or exterior scene the lighting needs to be realistic. Therefore, in an interior I usually use a mildly cold light from the windows, tinted with a shadow-casting warm light. The warm light source imitates the sun. Generally, the final image looks more delicious if besides the natural lighting it has a warm artificial light coming from the side. Moreover, If any of the spotlights or pendants in the scene are on, they have to produce their realistic light as well.


Lastly, when lighting settings meet our expectation we can assign all the materials and textures to the scene. Materials in an architectural 3D modeling is more than just a bitmap map with stucco, stone or wooden texture, it is also a number of settings that are responsible for the way an object will absorb or reflect light, whether it has rough, bumped or slick surface, whether it is translucent or refracting light rays. Quality of assigned materials can be a make-it or break-it criteria for a scene.

All materials and textures assigned – the rendering is ready to sell the design idea!

When all 3 components of a 3D scene: geometrylighting, and materials are in place, we let the computer do the work and start the rendering process. During the rendering process computer calculates the distribution of the light in the area. Main effort goes for calculating the bouncing of the light ray from every object in the scene. Basically, the computer is prototyping all the shadows and reflections that there are in a real life. Finally, after several hours of intense human-computer collaboration, we get a beautiful image.:)

If, by and large, the art of 3D Modeling & Rendering appears interesting to you, stay tuned! I will publish later several articles, gathering tutorial and resources which can give you a productivity boost in 3D modeling skills. As for now, –  start learning by doing! For the better results, always remember the golden rule: in any 3D Rendering there are 5 crucial components: design, composition, geometry, lighting and materials. Naturally, whichever is the weakest will represent the whole image, so always aim for a high-quality in each category:)!
