renderings: see beforehand what it will look like afterwards

The great advantage of visualisations is the photo-realistic representation of a future project in the planning phase. Even skilfully drawn hand sketches create ambience and breathe life into a design idea. Even more so, images and animations of a design created with the help of digital 3D computer graphics, so-called renderings, can convey a much better idea of a future room or building than floor plans and side views ever could. This makes it much easier to make decisions, for example in materialisation or design.

A photograph can show something that already exists. A rendering can illustrate a design idea, a project, a piece of furniture, etc. that does not exist yet and enables a presentation that seems real. Thanks to renderings, layman who have no experience in reading and interpreting plans can visualise and better understand the different phases of the project.

Basic principle of photorealistic rendering

Rendering refers to the process of calculating images on a computer using special 3D software. To do this, a 3D artist creates a scene based on CAD data using a virtual camera, lighting and material selection of all objects shown in the image. Rendering thus refers exclusively to images or image worlds generated and produced on a computer.

The creation of photorealistic, artificial images based on three-dimensional models requires a great deal of specialist knowledge about surfaces, colours, textures (texture of the surface) and lighting. With the help of the software, natural and artificial light sources can also be simulated, for example, to better depict the special features of an interior. The more details are included in the raw data, the more accurate and photorealistic the computer-generated image of reality will be.

Advantage of rendering

Professional renderings save valuable time, as all parties involved can see what the outcome of the building project will be, in advance. They help to make decisions and contribute significantly to eliminating misunderstandings. Uncertainties in the choice of colours and materials can be removed with the use of a rendering. A reception desk in 2 versions (e.g. wood or natural stone) with all its effects can be compared quickly.

A practical example

The pictures above show the rendering of the reception at Swissklinik in Pfäffikon before the start of construction and the photo after completion. This is a practical illustration of how the 3D artists at Erich Keller AG bring the customer´s wishes closer to reality even before implementation.
