This is the process in which a 2D image or video is created using the specifications of a 3D model with the help of 3D computer graphic rendering software. Some of the most common uses of this type of rendering include architectural renderings of developments and buildings, interior design renders of homes or individual rooms, renders of products, and designs or inventions often used by professionals and entrepreneurs. 3D modelling and rendering is extremely flexible, making it possible to create a 3D render of nearly anything you can imagine.
Understanding the 3D Rendering Process
The steps below describe the 3D rendering of 2D images. Animated videos can differ in a few ways. Although the process below is detailed as a linear process where step one follows step two, a 3D artist can perform the final few stages in any order. Also, understanding the client’s needs is an ongoing process throughout the project.
Understanding the Client’s Needs
To shape a model, a 3D artist must understand the project and its goals. By means of plans, sketches, and reference images given to the artist by the client, the person will begin by envisioning the project in his or her mind.
The artist then uses specific 3D modelling software to generate a digital model. This phase is equivalent to constructing the structure of a physical model. This model simply exists digitally.
The 3D artist applies the images to the 3D models so that they look as realistic as possible. This step is similar to painting a physical model or gluing materials and photographs to the surface.
Here, the artist sets up lighting within the 3D scene to duplicate lighting found in real-world settings. This can be thought of in the same way that a photographer or director would set up lighting prior to taking the photos or shooting the video.
Now, the 2D image or images are generated from the model. This is the actual rendering process. It is similar to taking a picture of a physical model. This is the only way to see the digital model that exists inside the rendering software.
Rendering could take several seconds or even several days, based on the intricacy of the model and the desired quality. The computer alone completes this task. In some cases, it is done on large rendering computers called render farms.
The drafts that are given to the client for review are lower in quality. This is done to speed up the revision process. Any necessary revisions to the scene, textures, or lights are made and the process is repeated until the design is perfect. Normally, changes can be made independently of each other so you can change the model without changing the texture.
The agreed-upon final 2D image or images are given to the client, hopefully no later than the target date. Based on the desired resolution, the images are provided in a specific format to support how the client will be viewing the image.
