What is Rendering?
Rendering is the process of converting a 3D model into a 2D image on a computer. Simply explained, rendering is the process of creating the actual image from the prepared part. Compared to real life, rendering is the equivalent to filming a prepared scenery. Over time, many different rendering methods have been established, ranging from non-realistic wireframe (polygon-based rendering) to more advanced methods such as ray tracing (following the path of light as pixels in image) and scanline rendering (visible surface determination).
How to process Rendering?
The following steps explain the complex process of the 3D rendering of 2D images. Even though the process is broken down into simple steps, we do not necessarily follow the order of these steps. As experienced engineers, we know that Step 1 “Understanding our client’s imagination” has to be followed throughout the process of rendering 3-dimensional data.
Step 1 “Understanding our client’s imagination”
Before the process starts, the 3D engineer needs to understand the client’s vision for the produced render. For that reason, planes, sketches and reference images are just as important as a frequent communication.
Step 2 “3D Modelling”
Our specialized engineers are working with different 3D software depending on the application. Analogous to this step is the creation of a physical object, but digitally.
Step 3 “Specific material and texture”
While applying images to the 3D model, the 3D engineer tries to make the model look as realistic as possible. Regarding the texture of the image, he modifies the appearance of the surface e.g. letting it appear glossy or matte.
Step 4 “illumination or lighting”
The 3D artist working on the project is generally interested in replicating real-world lighting. Just like a photographer that is adjusting the settings on his camera before taking the shot.
Step 5 “Actually Rendering”
It is the generating of a 2-dimensional image of the scene created in steps 1-4. The required time depends on the complexity of the scene and usually results in high-quality 2-dimensional digitals.
Step 6 “Refining”
Refining is one of the steps that has to be done throughout the whole process of rendering. It is the constant communication between our engineers and the client regarding present drafts. Generally, we prefer to be working with an integrated client, that always knows about the present steps of his project.
As the team of PLG Global, we are always considering our client’s requests regarding texture, lights and scene until the desired results are achieved.
Step 7 “Delivery”
As soon as the refining process has been finished, the agreed 2D image is provided to the client. Depending on the desired results, we are delivering the image in a specific format to support and size.
- 3D renders allow to view design before construction.
- It is an economic and convenient.
- Visually showcase complex simulations before manufacturing.
- Marketing efforts and market research before finishing.
- Allows dynamic experience for future customers.
Critical Factors of Rendering
- Depending on the complexity, rendering might be costly.
- Rendering cannot be seen as the 100% elimination of mistakes.
- Communication between client & engineer is the key to success
- It is possible to create a 3D render of just about anything imaginable
- It is the process of industrial design.
