Rendering is the process of creating a final image or animation from a 3D model. It is a crucial step in the 3D animation and visual effects pipeline, and it requires a good understanding of various rendering techniques to achieve the desired look and feel. In this blog post, we will explore different rendering techniques and their pros and cons, so you can make an informed decision when choosing the right technique for your project.
This is a complex question, but to create impressive images, we recommend checking out the following aspects of your imagery:
1. Style and Language:
Regardless of the style or visual language used, whether it be a collage or a rendered visualization, the ultimate goal is to create an atmosphere within the image that evokes a sense of impact and well-being for the viewer. It is important to keep in mind that the image should not be viewed as a standalone component, but rather as a part of the larger presentation. All images should be cohesive and relate to the overall graphics of the booklet, boards, or slides.
2. Ray Tracing:
Ray tracing is a rendering technique that simulates the behavior of light in a scene. It traces the path of light rays as they bounce off objects and into the camera, creating a more realistic image. This technique is used to create photorealistic images and is often used in film and television.
The main advantage of ray tracing is its ability to handle transparency and reflections, which produces more realistic images. However, it is a computationally intensive technique and can take a long time to render an image.
3. Light and Shadow:
Creating rendered images can be a time-consuming process, particularly when adjusting the position of the sun. The specific settings for day and time can greatly affect how light enters the environment and casts onto the architecture. Lighting plays an important role in interpreting the project, as Le Corbusier stated, "Architecture is the learned game, correct and magnificent, of forms assembled in the light."
When working on night scenes, it can be helpful to refer to the work of experienced architectural photographers for inspiration in developing the appropriate chromatic palette for the colors of the lights and the sky.
4. Camera View:
The camera view is an essential aspect of architectural rendering, as it can greatly affect the overall look and feel of the image. The camera view determines the perspective of the image and can be used to create a sense of depth and realism or to emphasize specific architectural features.
When choosing a camera view, it is important to consider the purpose of the image. For example, if the goal is to showcase the overall design of a building, a wide-angle view may be more suitable. This type of view allows the viewer to see the building in its entirety, and can also be used to capture the surrounding landscape and context. On the other hand, if the goal is to highlight specific architectural features, such as a grand entrance or a unique architectural detail, a close-up view may be more appropriate. This type of view allows the viewer to see the details of the building, and can also be used to capture textures and materials.
5. Materials and Textures:
One of the most important things to consider in architectural rendering is whether the materials specified in the project are clear and accurately represented in the images. It may seem like a simple question, but it is a mistake that is often made in the production of images.
For example, when using regular glass in a project, it is important to remember that it is both transparent and reflective, depending on the lighting and camera angle. These basic characteristics should be evident in the final image. Similarly, when using exposed concrete, it is important to consider the different casting techniques and molds that can be used. It's important to specify which one you are using in the project and ensure that it is accurately represented in the images.
6. Objects and Vegetation:
Having a well-stocked library of objects, particularly for furniture and decorative elements, is crucial for creating high-quality architectural renders. It is important to pay special attention to the objects in the foreground of a scene, ensuring that they are well-modeled and accurately convey their intended appearance. For example, upholstery should appear soft, not flat and faceted.
Another common mistake is improper scaling of vegetation, particularly trees. Keep in mind that trees are large and should be represented accordingly in the scene. While it is important to respect the landscape project, care should be taken to avoid covering important parts of the architecture with a tree canopy or positioning the camera in an awkward way.
7. Human Figures / Cutout People:
Human figures, also known as cutout people, are an important aspect of architectural renderings as they help to convey the scale and functionality of a space. They provide a sense of context and can help the viewer to better understand the purpose of the building or the space.
When incorporating human figures into an architectural rendering, it is important to pay attention to their scale and placement. They should be proportionate to the space and should be placed in a way that makes sense in terms of the function of the space. For example, people in a conference room should be seated at tables, while people in a park should be spread out and enjoying the space.
Human figures can also be used to create a sense of movement and activity within the space. This can be achieved by placing them in different positions and poses. For example, people walking or sitting can create a sense of movement and life in space.
8. Post-processing:
Post-processing is the process of editing and enhancing a rendered image before it becomes the final image. It is a crucial step in the rendering pipeline, and it can be used to make final adjustments to the image and to add final touches that can make the image look more realistic and polished.
One of the most common post-processing techniques is color correction. This involves adjusting the overall color balance and saturation of the image, to ensure that the colors look natural and realistic. This can be done using software such as Photoshop or Lightroom.
Another important post-processing technique is the use of filters and effects. This can include adding a depth of field effect to create a sense of depth and realism or using a bloom effect to create a sense of bright and vibrant light. This can be done using software such as Photoshop or After Effects.
We believe that the use of digital media, such as animations and virtual reality, for project presentations is a valuable new technique. With the advancements in hardware and software technology, it is becoming increasingly easy to produce this type of visualization. This allows architects to become more self-sufficient in the production of this content, by incorporating these elements in the early stages of the project development, rather than only in the presentation phase. This can lead to better and more accurate results.
