3D Modeling in Architecture Rendering Oversimplified

For generations, illustration has been an important part of effective architectural design. In our digital age, it has assumed numerous forms and continues to change rapidly. But what exactly do we mean by “computer-generated rendering”? What has the history of architectural visualisations looked like? What are some of the advantages and disadvantages of realistic 3D modeling? So what are some of the most regularly utilised design software and processes? In the following paragraphs, we will attempt to address all of these questions.

 Architecture Rendering

Before construction begins, architects and designers generate pictures of buildings and their interiors. The goal of these photos is to depict how a design will seem after it’s finished, as well as to highlight design nuances and elicit emotional responses to a project. A rendering is an artistic portrayal of a space’s final design in each scenario. 

History of Illustration 

Master builders were confined to flat paper plans documented with paint or ink long before the advent of computer technology. Architectural visualisations followed in the footsteps of fine art, and design illustration progressed in lockstep with new artistic approaches. Fillipo Brunelleschi created the first-ever example of linear perspective in 1415, employing a 2D picture to draw 3d for the first time in history. A 2D graphic might properly depict a finished structure thanks to this breakthrough.

Architects, influenced mostly by the German-born Bauhaus Movement, did not become a specialist group keen on merging the arts with industrial design until the early 1900s. Axonometric drawings took precedence over individual perspectives in architectural representations. These sketches were less ornate, more technical and geometric in nature, and concentrated on the shape of space. 

International Business Machines Corporation (IBM) developed the first computer-aided design cad online software half a century later. The evolution of computer technology has transformed today’s modeling and rendering practises, just as the evolution of fine art transformed architectural illustration during the Renaissance period. Architects in the twentieth century took pleasure in their stylized hand drawings, but in the twenty-first century, they are vying to use a growing range of sophisticated computer programmes.

A few key benefits

  •  It is preferred by clients. More clients are expecting the same from their hired architects as prominent design companies spread their cutting-edge, computer-generated ideas. 
  • 3D models are accurate and precise. Designers, engineers, and draughtsmen enter building measurements into modeling software, which then generates a model based on the exact requirements provided to it. The possibility of human mistake is considerably reduced. 
  • It’s simple to troubleshoot. Early in the project development process, creating detailed 3D models allows for easier problem-solving. The design may be swiftly changed to suit substantial changes, avoiding costly alterations during construction.
  • They are works of art that effectively excite and inspire both current and future clientele. They’re also essential components of any pitch deck, since they convey a project’s merits to potential investors.

Key Criticism of 3D Modeling

Despite some clear advantages, not everyone in the design world appreciates sophisticated modeling and rendering. Tatiana Bilbao, a Mexican architect, is one of these critics. Her design firm has ceased to produce representations. She claims that previous clients had lost sight of the “creative process” because they had “fixed a picture” of the end outcome in their thoughts much too readily. Collage, on the other hand, is her preferred method of visualisation since it emphasises the flexibility and collaborative aspect of design.

Common Softwares

Since computer technology disturbed the business, a variety of widely utilised applications have erupted onto the market.

Though each design business is unique and will select the tools that best suit its needs, the majority have embraced 3D modeling software such as AutoCAD, Revit, and SketchUp. Other applications like as Rhino, Grasshopper, Maya, and 3D Studio Max may also be used by businesses. 

Designers can utilise rendering plug-ins to add elements like shadows, reflections, and building materials to draw 3D model created with modeling software, resulting in a more full and realistic depiction of the design. Enscape, V-Ray, Flamingo, and Lumion are some of the most popular rendering plug-ins.


Architectural illustration has come a long way from its humble beginnings. Our contemporary era of computer-generated 3D modeling and realistic rendering is rapidly progressing, as the benefits of these visualisations are driving industry adoption. While some critics are wary of adopting technology for fear of unreasonable client expectations and suppressed creativity, the majority of design professionals are quick to adapt, realising the necessity to stay competitive.
