What is Rendering?

The process of converting a 3D model into a 2D image on a computer is called rendering. In other words, rendering is the process of creating the actual image from the prepared part. It can be said that rendering equals to filming prepared scenery. Different rendering methods like non-realistic wireframe (polygon-based rendering) or more advanced methods like ray tracing (following the path of ligh as pixels in an image) and scanline rendering (visible surface determination) have been established in time.

How to process Rendering?

Below you can find the steps which provide a detailed explanation of the complicated process of 3D rendering of 2D images. It must be noted that we do not follow the order of these steps even though we have prepared these simple steps in order to explain the process. We, as experienced engineers, know that we must follow the first step called “Understanding our client’s imagination” throughout the process of rendering 3D data.

The first thing the 3D engineers must do is to understand the client’s vision for the produced render before the process begins. In this regard, it can be said that planes, sketches and reference images are very significant alongside communication.
At PLG Global, we have specialised and experienced engineers who work with different 3D software depending on the application. Creating a physical object digitally can be regarded as a similar step at this point.

The main objective of the 3D engineers is to make the model as realistic as possible when they are applying images to the 3D model. The engineer must modify the appearance of the surface with regard to the texture of the image, which may include making it appear glossy or matte according to the model at hand.

The 3D engineer must work in a similar way to a photographer who tries to adjust the setting before taking a photograph. For this reason, replicating the real-life lighting is generally the focal point for the 3D engineer working on the project.
On steps 1 to 4, we have created a scene. It is in this step that the actual rendering begins. Now, it is time to generate a 2-dimensional image. The more the scene is complex, the more time is required. The result is high-quality 2-dimensional digitals.

Another part of the rendering process is refining. Refining process consists of the continuous communication about present drafts, which takes place between our engineers and the clients. It is always better for us to be working with an integrated client who has knowledge about the individual steps of their project, which gives us a cleaner communication.

As PLG Global team, we always prioritise our client’s requests regarding texture, lights and scene until we achieve the result in the way they desire.

Following the refining process, there is a 2D image that is agreed upon. According to the desired result, this 2D image is presented to the client in a specific format and size.

Advantages of 3D Rendering

  • Being able to view the design prior to construction
  • Economic and convenient solution
  • Showcasing complex simulation before manufacture
  • Marketing efforts and market research
  • Allowing dynamic experience for potential clients

Critical Factors of Rendering

  • Possible higher cost depending on complexity
  • Rendering gives no guarantee of 100% elimination of mistakes
  • Communication between client and engineer is the key point
  • Possibility to create a 3D render of almost anything
  • The process of industrial design
