From military labs to creations made on a phone

Picture a client meeting in 1993. You manufacture CNC machines. You have a catalogue of technical drawings, a handful of photos, and — if the client is lucky — a cardboard prototype. That same year, cinemas were showing “Jurassic Park,” where every frame of the dinosaurs took hours to render on hardware worth millions of dollars. Two different planets.

Today that gap has all but disappeared. The same technology that brought the T-Rex to life on screen now animates a CNC mill on your product page — on a reasonable budget. How did we get here? It’s a 70-year story that starts with the green glow of an oscilloscope screen.

What is computer graphics?

Computer graphics is the craft of turning numbers into images — from a simple chart to a photorealistic industrial animation. It rests on two fundamental models that still coexist in every visual project today.

Raster (bitmap) graphics — every image is a grid of pixels. In 1965, a 512×512-pixel screen was the state of the art. Today a smartphone in your pocket packs tens of millions of pixels, and rendered industrial animations run at 4K and 8K. This model dominates photography, film and product visualization.

Vector graphics — instead of pixels: mathematical equations describing shapes. A company logo, a technical drawing, CAD curves — all vectors. Perfectly sharp at any scale, from a label to a billboard. Every machine design starts life as a CAD model before it ever reaches 3D rendering.

The word “pixel” (from picture element) first appeared in 1965, in the context of digital television — before modern monitors even existed. For a decade it stayed pure engineering jargon.

Born in the Cold War

The history of computer graphics starts with military secrets, not artistic experiments. In the 1950s, computers filled entire rooms, cost a fortune, and were accessible only to the military and top universities.

The first “graphics” ever shown on an oscilloscope screen were radar data from air defence systems. This wasn’t about aesthetics — it was about an operator interpreting data fast. That requirement — a human has to understand the data instantly, without reading tables — became a founding principle of computer graphics that still holds today.

In 1960, William Fetter of Boeing coined the term “computer graphics” for the first time. His job was to visualize a pilot’s position inside a cockpit. The result was “Boeing Man” — the first digital 3D human figure in history, built not for art but for engineering.

The takeaway for manufacturing companies: computer graphics was an engineering tool from day one, not an artistic one. Its purpose was to make understanding easier — and that function hasn’t changed in 70 years.

Sketchpad — the first step toward digital drawing

In 1963, Ivan Sutherland at MIT built a program called Sketchpad — and effectively invented interactive computer graphics. For the first time in history, a person could draw on a screen with a light pen and see the result instantly.

Sketchpad introduced concepts we now take for granted: copying objects, keeping shape proportions, automatic line-snapping. It was also the seed of object-oriented programming — every shape drawn was an object with its own properties.

In 1988, Sutherland received the Turing Award — computer science’s equivalent of the Nobel Prize — specifically for Sketchpad. Asked how hard it had been to build, he answered simply: he didn’t know it was supposed to be difficult.

The Utah Teapot — the model that changed 3D graphics

The 1970s saw the birth of three-dimensional graphics, and its centre of gravity was the University of Utah. The founders of Pixar, Adobe, Atari and Silicon Graphics all passed through there.

In 1975, researcher Martin Newell needed a simple object to test new shading techniques. His wife, Sandra, suggested a model of their household teapot. The choice turned out to be technically brilliant:

The popular version of the teapot is slightly squashed — while demonstrating object scaling, Jim Blinn accidentally shrank the model vertically, and it stuck. That “squashed” teapot made history. You’ll find it in Toy Story, in 3ds Max, and in dozens of other programs.

The Utah Teapot is still one of the most recognizable symbols in 3D graphics. A good test model can outlast plenty of industry standards.

Ever wonder how the mouse and desktop ended up on our desks?

While researchers were exploring 3D space, a different revolution was brewing at Xerox PARC. In 1973, the Xerox Alto was born — the first computer with a mouse, a portrait-orientated monitor shaped like a sheet of paper, and a graphical desktop with windows and icons.

It was a computer from the future. The catch? It cost as much as a car, and nobody quite understood why an ordinary person would need a “mouse.”

It wasn’t until 1979 that Steve Jobs saw the Alto in person and understood it was the future.

That visit inspired the Apple Lisa (1983) and Macintosh (1984) — the machines that kicked off the personal computer era. A few years later Microsoft launched Windows, opening a new chapter: the graphical interface had made it into every home for good.

Did Hollywood pick up CGI quickly? Not exactly!

“Westworld” (1973) showed the world through a robot’s digital point of view. “Star Wars” (1977) used vector animation for the Death Star. The real breakthrough was “Tron” (1982) — the first film where a computer-generated world became a fully-fledged set.

There’s an ironic footnote: the Academy refused to nominate “Tron” for a visual effects award, ruling that using computers counted as cheating. A few years later, CGI became a standard no action film could do without.

For comparison: a single frame of “Jurassic Park” took several hours to render on hardware worth millions of dollars. Today, an average laptop would handle the same job in a few minutes.

Video games and the GPU war

“Doom” (1993) and “Quake” (1996) set the standard for FPS games. Demand for ever-better real-time 3D graphics kicked off a race that reshaped the entire tech industry. 3dfx, ATI and NVIDIA fought over every million players. In 1999, NVIDIA launched the GeForce 256 — the first graphics card to take 3D calculations off the CPU’s plate entirely.

Graphics processors built for massively parallel computation turned out to be perfect for training neural networks. Most AI models today are trained on GPUs. The gamers of the ’90s unknowingly bankrolled the infrastructure that would power 21st-century AI.

Ray tracing and generative AI — where film and reality start to blur

Ray tracing — tracing light rays and simulating their physical behaviour — had existed since the 1980s as a supercomputer-only technique. In 2018, NVIDIA brought it to consumer RTX graphics cards. The effect: shadows, reflections and lighting in animation started looking like they came straight out of a cinema production.

Generative AI changed the rules again. Tools like DALL-E, Midjourney and Stable Diffusion can turn a text description into an image in seconds. Type “compressor turbine, cross-section, studio lighting” and a moment later you have a starting base for further work.

The scale of the shift: from the launch of the major generative tools (Midjourney, Stable Diffusion, DALL-E 2 — all in 2022), the number of AI-generated images passed 15 billion by mid-2023 (source: Everypixel Journal) — roughly as many as traditional photography produced in its first 150 years combined.

Generative AI isn’t replacing 3D animation for industry — it’s replacing stock photography and generic graphics. A technical animation that shows how a mechanism works from the inside needs engineering knowledge, not just aesthetic sense. You can’t prompt your way to an accurate cross-section of a five-axis CNC mill.

3D animation in industry: what does this mean for your company?

70 years of computer graphics history lead to one practical conclusion: technology once reserved for NASA and Hollywood is now a marketing communication tool for manufacturing companies.

For a maker of CNC machines, medical equipment or HVAC systems, 3D animation today does what no photo or brochure can:

• shows the inside — cross-sections, mechanisms, media flow
• explains how something works — step by step, without words, in any language
• removes the need for show-and-tell prototypes — the customer understands the product before it even exists
• works around the clock — on the website, in a sales pitch, at a trade fair

If your company sells something technically complex and is still showing it to clients through a PDF or static photos, it’s worth asking whether you’re losing contracts to a competitor showing the same thing in motion.
