Case Details

Implementation

EasyAR Mega has painted a “3D love-letter map” of the Ming Tombs, just like a lovesick painter whose brush flows with tender, meandering grace. Slip on a pair of XREAL Air 2 Ultra AR glasses, and the six-century-old imperial necropolis slowly stirs back to life…

With the XREAL Air 2 Ultra on, the vermilion gate of Changling seems to come alive. Then, a virtual Ming-dynasty guide glides in with a gilded token in hand, careful not to disturb the ancient silence of the crimson walls. Real golden glazed tiles mingle with virtual honor guards, and for a fleeting instant, you can’t help but wonder: have you somehow brushed aside six centuries of dust and silence, tumbling straight into the Yongle Emperor’s own twilight and dawn?

Move on to the Stele Pavilion, and before your fingertip can feel the coolness of the stone, a golden dragon bursts forth from the inscribed text, coiling around the imperial stele in a blaze of light so dazzling it feels like a meeting of “golden wind and jade dew” – a phrase from classical poetry that speaks of rare, sublime encounters. This is no period-drama daydream; it is the new “time-bridge” built over the Ming Tombs by EasyAR Mega’s spatial computing technology, which has turned imagination into reality and equipped the site with a system featuring “smart navigation + immersive story-based tour”. It’s like having a bird’s-eye view while standing right in the middle of history – time blurs, and the past suddenly feels immediate, as if you’re just having a friendly chat across the centuries.

Spatial Computing Paints a “3D Love-Letter Map” of the Tombs

Don’t let “spatial computing” conjure up cold, hard tech. In truth, it’s wonderfully tender. Boasting all the grace and flow of a painter’s finest brushwork, it has drawn a “3D love-letter map” of the Ming Tombs – every inch of land, every architectural detail inscribed with affection, quietly capturing the very soul of the site in digital form.

With panoramic cameras strapped to their backs, the crew ambled along the Sacred Way, through the halls, and had the whole place scanned in no time. The lenses recorded every brick pattern and carved curve with crystal clarity, generating a point-cloud map – a “digital twin” of the tombs that mirrors the real thing. Even the moss in the brick crevices, the old marks on the walls, and the carvings on the marble steps are visible in the virtual space.

When visitors don the AR glasses, the onboard sensors act like sensitive antennae, constantly “reading” the surroundings: spotting the golden bricks of the Ling’en Hall floor to pinpoint the visitor’s location on the map, or recognising the stone censers of the Five Offerings to trigger the corresponding ritual-history visuals.

This precision holds a kind of tender deference to history. It works to the centimetre: the exploded-view AR model of the “Jiangshan Yonggu” (Eternal Empire) stone relief clings to the real object like lovers embracing, with every tier of the Sumeru pedestal, every dragon scale, perfectly aligned. It also extends equal care to the entire tomb complex, from the main gate to the Fangcheng (Square City) and the Minglou (Soul Tower). Wherever you go, whether for navigation or interpretive content, the AR overlays stay firmly “stuck” to reality, overturning the old AR pitfalls of no navigation and virtual drift. Best of all, not a single nail was driven into the relics, nor a single device installed; the tombs retain their original antique charm, untouched by modern interference.

Virtual Content: A Perfect Fit That Brings History to Life as a Charismatic Beauty

Older AR guides always felt like gazing at a beauty through fog with virtual and real elements each “doing their own thing”, and any slight movement would break the spell. However, the AR at the Ming Tombs feels bespoke, snugly attached to each scenic spot, making history come alive as a vibrant, warm-hearted presence.

With its red walls and golden tiles, the main tomb gate is imposing and grand. Here, the AR guide brings a virtual honor guard to life. Visitors step into the royal sacrificial experience amid ranks of soldiers and the sound of drums and horns.

At the Stele Pavilion, abstract textual explanations are transformed into lifelike 3D models, contrasting the double-eaved and single-eaved pavilion styles and highlighting the supreme rank of Changling’s pavilion. Then, as you enter, the breathtaking golden dragon soars from the stele and spirals upward – each spiral a vivid reenactment of imperial grandeur, as if the very stone had come alive to tell its story of power and majesty.

The Ling’en Hall, the architectural centrepiece of Changling, is the largest surviving Ming-dynasty wooden structure in China and is ten metres wider than the Hall of Supreme Harmony in the Forbidden City. Its sixty nanmu wood pillars, which support the roof, are national treasures in their own right. The pillars, hauled from deep forests in Yunnan and Sichuan, stand some 14 metres tall and 1.17 metres across, with the thickest taking two or three people to wrap their arms around. Getting the timber to Changling was once no small feat. With no modern transport, the craftsmen used the rainy season to their advantage, floating the logs downstream on swollen rivers and then hauling them overland to Beijing. A single pillar took up to three years to deliver, and its cost equalled a year’s living expenses for 200 ordinary households at the time.

Today, as you enter the hall and look up, you see these nanmu columns still standing straight and proud after 600 years, their subtle “golden” grains gleaming in the light. The “Jiangshan Yonggu” stone relief and the faded painted beams still speak of Ming craftsmanship. EasyAR Mega’s spatial computing brings the hall to life in stunning digital detail, making the nanmu pillars glow with renewed radiance. Its 3D exploded view of the stone relief lets visitors explore every layer, from the base to the uppermost carvings, tracing the curling grass motifs and dragon scales on the Sumeru pedestal – as if they could almost feel the Ming artisan's handiwork beneath their fingers.

At the Lingxing Gate, looking up at the star chart feels less like a lesson in history and more like a rendezvous with the heavens themselves – a moment when you and the Ming-dynasty sky share the same moonlight. Here, AR markers pinpoint the “Ziwei Star” (Polaris), the celestial anchor of the emperor’s earthly claim. It turns out that when the Yongle Emperor chose the tomb site, he deliberately aligned Changling’s central axis with the Pole Star, which ancient Chinese believed was the “Emperor’s Star” – a design that asserted his “Mandate of Heaven” and embodied his hope for eternal dynastic rule. The star chart’s brightness shifts with the daylight, soft in the midday glare and clear as dusk falls, as though ancient wisdom and modern tech were in quiet accord.

At the Stone Five Offerings, an animated sacrificial scene ignites virtual flames on the ritual vessels, demonstrating the full funeral ritual of an imperial burial. For a moment, you could almost believe you were standing right there at a real Ming royal sacrifice.

At the Fangcheng and Minglou, a virtual Zhu Di appears in his dragon robe, reciting his own poem like a nostalgic old man as he reflects on his legacy and hopes for his descendants. The AR overlays his figure onto the Minglou, as if the emperor never really left, still guarding the tranquil haven he had chosen. At that moment, the soaring eaves of the tower seem warm. They are no longer cold stone, but a vessel of the Ming dynasty’s grand history.

Weathering the 45°C Heat: A Tech-and-History “Love Affair”

Ground temperatures hit 45°C in summer, with the sun scorching the red walls – it’s the kind of heat that really puts the tech to the test. However, this AR guide, like a steadfast lover, keeps its composure even in the blistering heat, engaging in a romance with the tombs that deserves a place in AR history.

The XREAL Air 2 Ultra’s electrochromic lenses are remarkably adept at handling glare. A simple voice command adjusts the tint, darkening under strong sun and lightening in the shade, so you can see both AR content and your surroundings clearly. It’s a nice touch that ordinary sunglasses can’t match.

EasyAR Mega’s cloud-edge collaborative architecture also “cools down” the device: heavy tasks like 3D model rendering and data processing are offloaded to the cloud, leaving the display as the glasses’ sole task, with each playing to its own strengths.

Even more heartening is EasyAR Mega’s unwavering respect for the relics. All AR content is woven around the artifacts without ever touching them, satisfying visitors’ curiosity while leaving the originals untouched. It truly delivers the “all-of-the-above” ideal.

In the most romantic way, this project opens a gateway to the Ming dynasty, turning history from cold text into something visible, tangible, and emotionally stirring. Perhaps this is the best way to preserve and pass on culture: letting our ancestors’ wisdom, with the aid of modern technology, cross the ages and find its way into ordinary people’s lives – in a way that feels both sci-fi and deeply down-to-earth.
