The moment architects and 3D artists replaced their drawing boards and sketchbooks with computer-based alternatives, the way of creating architectural rendering and visualization has changed a lot – so much that it’s hard to recognize it.

Programs like CAD, V-Ray, and many others have brought the power of automation and placed it in the palms of capable 3D professionals who know how to harness its potential and put it to good use. Nowadays, there are as many rendering techniques as there are rendering software tools out there, and it is quite easy to lose yourself in so many choices.

The ability to use the latest software tools to create incredibly realistic 3D architectural renderings and models paved a new way for architects, engineers, and designers. Aside from helping architecture, engineering, and construction industries, architectural rendering is now much more than just a process of creating photorealistic and immersive images.

It’s now a new marketing and sales tool for a wide range of industry professionals. Since 3D rendering has become a widely popular tool of expression, every industry has become increasingly interested in this powerful tool and all of the benefits it can offer.

Homebuilders, contractors, interior and exterior designers, movie makers, architects, and 3D artists use various rendering software tools to beat their competition and exceed their clients’ expectations. Let’s see the five most important stages of using rendering software and how rendering solutions can help.

Defining Rendering Software

3D rendering software is a program that helps 3D artists to place their 3D models into photorealistic 3D images or environments. With 3D rendering tools, media developers, 3D artists, and graphic designers can insert disparate characters and objects imported from 3D modeling programs into any virtual or graphically appropriate setting.

These 3D rendered images are usually interactive, navigable, and scalable. Depending on the software’s features, most 3D rendering tools come with animation features or can be integrated with animation programs to allow professionals to create incredibly realistic and immersive scenes used in television shows, movies, video games, and other media.

Rendering software provides a range of features such as texturing, lighting, shadowing, and more. Visual artists in web design, advertising, architecture, automotive, and entertainment industries use these software tools to create the most realistic and lifelike scenes for use in client or media engagement scenarios.

Some of the best rendering software tools are V-Ray, Lumion, Blender, Maya, 3ds Max, and many others.

How These Solutions Help

Architectural rendering is essentially a process of creating 2D and 3D animations and images to better illustrate and visualize proposed architectural designs. Through rendering, 3D artists can create realistic and mind-bending visualizations that help communicate ideas and showcase projects.

More importantly, architectural rendering was once a time-consuming process that required exceptional skills and thorough knowledge. Fortunately, the appearance of real-time rendering programs has made architectural rendering and visualization widely accessible for designers, architects, engineers, and 3D artists.

3D professionals have an array of powerful tools for real-time architectural rendering and visualization, ideal for any design workflow. In fact, the best rendering tools empower users to explore different design possibilities and take their creativity to the next level.

These powerful software tools allow artists to create fantastic rendering works with just a few clicks. They can easily transform their 3D models into a landscape or 3D building rendering. Top rendering software tools include some of the best features, such as:

• Still renderings
• 3D walk-through

• Cross-sections and floor plans
• 3D photorealistic, real-time rendering
• Panoramic 360-degree rendering

Why You Should Learn to Use One

The introduction of real-time rendering software tools has made architectural rendering a means for improving daily workflows. What was once an expensive and time-consuming process is now much faster, effective, and accessible. Artists have realized how beneficial the use of rendering software can be. It can help:

• Validate your ideas – 3D rendering has become the bridge between the client and the artist. It improves communication and helps designers and architects communicate their ideas in a much more effective and understandable way.‍
• Eliminate human error and receive better feedback – 3D rendering in real-time is the best way to eliminate possible design errors before they escalate beyond control. On the other hand, clients can visualize a design before it’s built to get the feeling and the overview of the space. Moreover, artists can use rendering software tools to create immersive virtual worlds to leave their clients in awe.‍
• Exceed your clients’ expectations – when clients can see your ideas with their own eyes; you can easily highlight the best part of your design and create the most realistic 3D renders to exceed the expectations of your clients by offering them to make changes on the go.

In the age of the internet, architectural rendering and visualization have long surpassed their initial purposes and are now more used to communicate between artists and clients. The truth is that both techniques have helped countless industries evolve due to so many possibilities they provide.

Many professional 3D artists, including developers and realtors, use CGI’s to support their marketing strategies by including 3D renders in their sales techniques. The more graphical software and digital hardware evolve, the more visual mediums become available in the 3D rendering industry.

Each medium offers a range of individual benefits and advantages. Now that we’ve cleared the most important things about the importance of rendering and rendering software tools, let’s see the five most important stages of using rendering software that you may be able to use in your own works.

Buffering Images

The best and most effective form of 3D visualization will always be the main part of both online marketing and print-based content. With the rise of visual storytelling, a strong and compelling 3D visualization and CGI gives an artist the advantage of harnessing the potential of modern technology to achieve stunning levels of realism and effects in a single render.

If you want to showcase your development in the best way possible, buffering images to prepare them for rendering is an excellent way to prepare your works for being easily shared on social media, sent electronically, or easily printed. The buffer is the memory in a camera, used to store image data before it is written to a camera’s memory card.

The bigger the size of the buffer, the more images you can store. The term buffering refers to the process of temporarily storing images as they are written to the camera’s memory card. In the case of rendering, we’re talking about preparing image data for further processing.

Mapping Colors

The process of applying materials to your 3D model to prepare it for rendering is known as mapping. Before materials can be assigned, your 3D rendering tool must know how to apply them. That includes several considerations such as mapping colors, tiling, and material orientation, among many others.

Mapping colors is the next stage in preparing your model for material application and sending it further down the rendering funnel. Once the mapping is complete, your model is ready for color and material application. Color or tone mapping determines which color operations are applied to the values rendered and the user interface inputs.

It dictates the way the rendered pixels are displayed. 3D artists often change the color mapping according to their artistic purposes. However, we recommend that you leave the color mapping settings at default for more consistency.

Sampling Images

When working with a renderer to render an image, your software must determine a color value for each pixel. It must examine the scene to do that. Most top-class rendering software tools, like V-Ray, have a feature called an image sampler.

Image sampling is the process of calculating a pixel’s color based on the colors around and within it. Each pixel in an image can have only one color. To determine the right color for each pixel, your rendering software uses colors from different parts of the pixel itself and all available pixels around it.

There is a range of different sampling methods to look into:

• Fixed-rate sampling – fixed-rate image sampling is a method of taking the same number of samples per pixel.‍
• Adaptive sampling – a method of taking a variable number of samples per pixel. The number depends on the varying intensity of the pixels used.‍
• Adaptive subdivision – this method also depends on the varying pixel intensity and allows the artist to divide the sampled image into an adaptive grid-like structure for further refining.‍
• Progressive – this method refers to the progressive sampling of the entire image.‍
• Min shading rate sampling – prepares your images for adding other effects like area shadows, GI, glossy reflections, etc. This method is best used with the progressive method as it helps shorten the time it takes to render high-volume scenes.

Global Illumination

You can’t create a mind-bending, well-rendered image without adding proper lighting and illumination. Lighting is probably the most important step in creating a photorealistic rendered image. The selection of global illumination starts with choosing the right lighting attributes such as intensity, location/angle, source, and color.

The best way to introduce global illumination to your rendering scene is to use multiple light sources. Take a look at some of the most photorealistic architectural renderings for the best example. It is highly unlikely that the artists who have created such works of art used only one well-selected light source.

To make sure your scene is properly illuminated, you are required to use a combination of different kinds of lights. Since rendering is essentially an effort to mimic the real world, adding attenuation and shadows is one of the most important steps in creating a stunning and photorealistic rendering result.

You can also consider adding special effects and reflections to give your rendering the most photorealistic appearance possible.

Combining all Rendering Elements Together

Once the images, colors, cameras, lights, and materials are prepared and ready, it’s time to select the most appropriate background to combine all rendering elements together and complete the entire composition.

If your clients require it, you can add landscaping elements and people. To achieve the highest quality 3D renderings, we recommend that you use the most advanced computer configurations. Place your model on rendering and watch the magic happen as your machine turns your model into high-resolution images.

If you need to create effective and unique content for marketing purposes, using a specialized camera might be useful. Some cameras allow you to scan existing objects and structures and use the scans to create photorealistic virtual tours of already completed projects.

The camera captures image data that can be used to create a 3D model and further customize it to display a preferred style view of a structure and its interior. You can decide to either animate or render the captured image data, depending on your goals and the client’s requirements.

Most modern clients prefer 360-degree panoramas, 3D animations, and virtual tours when it comes to presenting your rendering works – 360 panoramas are currently top marketing and selling tools for realtors and members of the property community.

These five stages of rendering will help to consistently provide your clients with mind-bending computer-generated animation and imagery.

Conclusion
