In Part 1 of the Trends in Visualization series, we looked at the origins of architectural rendering and how the advent of BIM shifted the practice from pencil and paper to digital modeling. Today, I want to share a personal story from a client meeting—and why I believe real-time rendering is becoming one of the most critical tools in the AEC industry.
I recently joined a client meeting with an interior designer for a small restaurant project. The designer had lugged multiple crates of material samples and heavy binders across the subway. Despite the effort, the clients sat uncomfortably, trying to imagine how those tiny material swatches would look when applied to a grainy, outdated rendering.
“I’m having a hard time visualizing it,” they admitted.
The meeting went on, with sample books scattered across the table and sticky notes labeling finishes as “ceiling,” “wall,” or “floor.” A few tentative decisions were made, but ultimately, another meeting, with more samples, was requested. As the clients left, they turned to me and asked, “Can you show us a rendering of these materials applied?”
That moment stuck with me.
As architects, we develop a sort of superpower: we can translate floor plans into fully formed buildings in our minds, map sections to human-scale spaces, and anticipate the spatial feel of a room just by looking at a detail.
But most clients can’t.
Later that day, I met with the same client to review an interior detail. We debated finishes and layout options for hours. Finally, the client threw up their hands:
“I can’t decide based on this section drawing. Show me a render with different thicknesses for A and B—otherwise I just can’t picture it.”
And that’s the reality: It’s not real to them without a picture.
Real-time rendering closes the gap. Clients no longer have to cross their fingers and hope they chose the right architect—one who will deliver their vision. Instead, they can participate in the design process, see how a space feels, and confidently make decisions before construction begins.
Those who can render on the fly—adjust finishes, flip between options, and simulate light or movement—have a massive edge. These are the firms winning more projects and earning deeper trust from their clients.
A Google Trends search reveals two major takeaways:
Why? Most often cited reasons:
This quote from the founder of D5 Render at Autodesk University sums it up:
AU 2023: “What is D5 Render?”
AU 2024: “I’ve heard of it but never tried.”
AU 2025: “We’re already using it. We need more licenses and training.”
In Part 3, we’ll dive deeper into D5 Render—what makes it so powerful, and why it’s rapidly becoming the industry standard for real-time architectural visualization.
