Interior design is a very broad field which embraces a great deal about art, culture, social tastes, lifestyle choices, and more. It involves everything from the planning and organization of space and lighting to the selection of materials, textures, furniture and accessories. In most cases, modern interior design modeling is based on both 2D (image) and 3D (space) modeling in frames of a very limited real estate. Functional approach based on economy and convenience became key points. Thus, the first step for an artist (interior designer) is to create a successful 3D interior model which will be as much functional and convenient, as aesthetically pleasing.
