Architectural Rendering Software

The tools of the trade have come a long way since drafting tables, triangles and scale rules. Now that nearly every office and household owns a computer, the work that we do as designers is largely digital.

Software tools play a significant role in the life of an architect, and one of the major benefits of these programs is the ability to create digital architectural renderings. In this article, we discuss the various software, benefits, and resources to get you started.

What is architectural rendering software?

Architectural rendering software is used to create images and environments that resemble the real world.

Architects, students and visualizers use this technology to create perspectives, videos, and immersive tours of their projects. This allows clients, stakeholders and peers to view and experience the buildings long before they are built.

The primary role of the software is to process model information to generate a rendered image. These programs use different kinds of rendering techniques to perform the task.

Some software uses ray tracing as the method of rendering, which is capable of producing more realistic images at the expense of much longer waiting times. Other program’s use rasterized rendering to create images, and these images can be generated in a matter of minutes.

Many programs also feature extensive asset libraries, which can include such elements as materials, plants, furniture, objects, and environments that can be used alongside your 3D model.

Ray tracing vs rasterized rendering

Ray tracing and raster based rendering are both widely used in the architecture industry. The main difference, and the main reason for the massive gap in rendering times between the two, lies in the way they perform the rendering computations.

Ray tracing uses a large amount of computing power to simulate the actual behavior of light within the scene, accounting for every single ray spreading out onto surfaces, reflecting and refracting off of materials and objects.

Meanwhile, rasterized rendering takes shortcut approaches to achieve similar results. Raster based rendering programs use graphics power to estimate things like reflection and light, causing the final image to be less accurate, but often still satisfactory for many architects’ needs.

What is real-time rendering?

Real-time rendering is used to move around and interact with a render environment. The term refers to the quick and constant updating of rendered imagery, such that it feels real-time and interactive.

This type of interface allows for high quality previews within the viewport before creating a final image. The preview makes it easier to adjust things like camera angles, textures, light, and shadow, and can also guide designers in making informed decisions about the spaces.

There are real-time rendering tools for both ray tracing and raster programs, and as computers continue to improve, real-time solutions will become more widely available.

Essentially, these programs make use of powerful computer hardware to create video game-like environments out of your 3D models. Images are updated with every movement and can be synchronized to update with every change to the 3D model as well.

Why is it important to have good rendering software?

Realistic renders, which were once an artform only achieved by the finest artistic hands, are now within arms reach with some of the latest software products.

A high quality rendering can be the difference between winning and losing a project, and in the increasingly competitive architecture industry, a stunning image can make a big difference.

In order to produce high quality visuals to showcase your projects, you or course need to using the right tools. Having good rendering software is vital to ensure that your designs are shown in the best way possible.

With fast, accurate, and visually pleasing renders, you can save time and resources by getting it right the first time around.

What is the best software for architectural rendering?

There are plenty of software programs available for architectural rendering, but choosing the right one can be a tricky task. Each has its own benefits, and you’ll want to find one that suits your needs while also being compatible with your other programs.

If the rendering software works well with your current 3D modeling workflow, it can be integrated more seamlessly into your overall production process.

…and so here’s a breakdown of some of the best software applications for architectural rendering:

Vray

V-Ray is a powerful rendering engine that runs as a plugin for 3D modeling programs. It’s developed by the Chaos Group, and uses ray tracing to create true-to-life imagery.

V-Ray is one of the industry leaders for architectural rendering due to it being capable of achieving high level photorealism, but it has long been behind in terms of render speed, interface, and ease of use.

Their latest versions, however, have addressed these concerns with intuitive new features like real-time rendering, interactive modes, and a new look for the V-Ray panel.

Additional features include built-in materials, an online asset library, and compatibility with cloud rendering services. The asset library, Chaos Cosmos, allows you to add detailed, render-ready 3D content to your V-Ray projects in minutes.

The cloud service, Chaos Cloud, is a one-click cloud rendering solution. V-Ray is compatible with render farms and other cloud rendering solutions as well. These services take the load off of your computer by rendering your image on a much larger network of computers to save you time and resources.

Corona Renderer

Corona Renderer has been growing in popularity due to its simple settings and realistic results. It solely uses CPU power to render images, and it uses a lean ray tracing process to produce photorealism within reasonable rendering times.

At the moment, the only fully supported application is Autodesk 3ds Max. However, the developers have Cinema4D, SketchUp, Maya, and Blender versions in the works.

For 3ds Max users, Corona is available for both Windows and Mac.

FAQs

Which is the easiest rendering software?

Everyone has different needs, making it difficult to determine which software is truly the best for rendering. Some people will favor only the most realistic options, while others will favor the most practical applications to use.

Final output can be largely debated, but user experience is a much more concrete aspect to draw comparisons from.

Known for having one of the most simplistic interfaces, Twinmotion is regarded as the easiest to learn rendering program in the industry. Its settings and functions are built around icons, and the navigation controls are similar to gameplay.

Now that it’s powered by Unreal Engine, users get the best of both worlds for realism and ease of use.

Do architects use Lumion?

Many programs have Lumion beat in photorealism, control of settings, and interoperability, but architects continue to use the program on a regular basis thanks to its impressive speed and user-friendliness.

Its massive library of built-in trees, people, and vehicles make it fast and easy to populate a scene, set up an image, and render. Power users are capable of creating huge city scenes in Lumion for professional render work, and the straightforward video tools make it simple to create video animations.

This versatility and the ability to effortlessly visualize a space for presentations keeps Lumion around as a mainstay in architecture offices around the world.

Which architectural rendering software is best for a mac?

Unfortunately, many architectural rendering programs do not run on MacOS. Popular software such as Enscape, Lumion, and Vray, are limited to Windows PC users.

However, Epic Games has recently added Mac support for Twinmotion, making it the most ideal solution for rendering on an Apple computer.

3ds Max users can also use Corona Renderer for photorealistic rendering on a Mac. For other 3D modeling and rendering needs, there are a few alternatives available as well, including Blender, Cinema 4D, and Modo.

To conclude

Technology has drastically changed the way architecture is practiced. Software tools have quickly become the primary instruments of architects around the world to document buildings and communicate ideas.

Rendering programs are becoming more powerful and easy to use, and it’s important to keep up as to not be left behind. High quality renders are no longer out of reach, and there is software available for all workflows and price points.
