The concept

La Lagartera awakens

The show is based on the story that inspired Toledo: a great flood drags alligators, turtles, and river fauna to a high mountain cave. When the water recedes, they are trapped. The alligator survives by devouring the rest.

Toledo turns this story into a metaphor for good rains and abundance. The spectacle takes up this idea to show La Lagartera, after its conservation, as a living organism returning to the city of Monterrey.

The challenge

Mapping an artwork of the dimensions and topography of La Lagartera was, with traditional methods, almost impossible.

So we invented a new method.

The method · generative workflow

From a photo to a
3D organism

We did not adapt the artwork to videomapping: we adapted videomapping to the artwork. We designed a generative workflow from start to finish —3D reconstruction, depth maps, meshes, and frame-by-frame animation with machine learning— executed on local models.

Capture

A single image originates everything

Everything is born from a zenithal drone shot of La Lagartera. That real photograph becomes the geometric and chromatic base for every subsequent step of the workflow.

Depth

Reading the relief's topography

We estimate a depth map that translates ridges, cracks, and cavities into three-dimensional information. It's the bridge between the flat image and the real volume of the piece.

3D Reconstruction

A mesh that replicates every scale

With generative tools we reconstruct extremely high-density models and meshes —over 5 million polygons— that reproduce the exact surface of the artwork to design and preview the show.

Frame-by-frame animation

Machine learning, on your own machine

On that base, we animate frame-by-frame with machine learning models executed locally in ComfyUI. Each frame is synthesized guided by depth and mesh, fitting into the piece's geometry. No cloud, no external services: total control over the result.

Seis acts, from darkness to light

Opening0:25

Toledo's voice

The sculpture remains in almost total darkness. Francisco Toledo's voice is heard with a phrase about La Lagartera, water, and abundance.

Mapping

The phrase appears written on the sculpture or reflected in the water.

Lighting

Almost complete darkness, with just a minimal breath of light.

Laser

Fire

Audio

Silence. Toledo's voice enters and, at the end, a deep drone anticipates the awakening.

Part 10:50

Nature overflows

The great flood sweeps away alligators, turtles, and river fauna. The show starts from the brute force of nature.

Mapping

Water rising violently: currents, foam, mud, and whirlpools. The relief appears and disappears under the storm.

Lighting

Low blues and grays. Brief white strobes reveal scales, ridges, and cavities.

Laser

Diagonal rain, lightning, and grazing lines that mark the speed of the water.

Fire

Audio

Pre-Hispanic percussion, strings in tension, rain, wind, and thunder. Everything grows to the limit.

Part 20:40

The water recedes

The flood has passed. The water drains and the sculpture begins to reveal itself. The calm is false: something remained trapped inside.

Mapping

Water dripping and sliding down the relief. The ridge, cracks, and crevices appear for the first time.

Lighting

Cold, damp light, with silver reflections and a slow breathing of light.

Laser

Very soft strokes, almost grazing, like steam or water draining over the stone.

Fire

Audio

Dripping, water draining, and a very faint solo cello. The percussion disappears.

Part 31:05

The alligator devours

The animals were trapped with the alligator. There is no way out. The sculpture becomes a predatory organism.

Mapping

The cavities become cave mouths. Turtles, fish, frogs, and crabs appear in flashes. Bites and shakes are hinted at inside the stone.

Lighting

Hard contrasts, cavities in total shadow, dark ambers, and deep reds on the ridge.

Laser

Aggressive and angular cuts. The space becomes a cage.

Fire

Low, precise shots synchronized with the lunges. Dramatic, not celebratory.

Audio

Dry percussion, dissonant strings, animal breathing, and cracking from inside the stone.

Part 40:45

Second flood

The water returns, not as a disaster but as a force that envelops, drags, and transforms what was left in the cave.

Mapping

The piece is covered with water again. The trapped animals dissolve in the current and the sculpture turns into waves.

Lighting

Dense blues and dark greens. Fluid pulses that accompany the new rise of the water.

Laser

Broad currents, enveloping diagonals, and the sensation of water filling the space.

Fire

Isolated strikes to sustain the climax, less intense than in the previous part.

Audio

The full orchestra enters. Pre-Hispanic percussion returns, integrated into the crescendo.

Part 5 · closing0:55

The good rains

The water no longer destroys: it blesses. Toledo's universe emerges whole and the restored sculpture returns to the city as a symbol of abundance.

Mapping

Luminous water running across the piece. The alligator, turtles, frogs, fish, and crabs appear clearly. The relief is drawn as if Toledo were tracing it again.

Lighting

Damp greens, soft amber, and bright whites. The sculpture reveals itself whole, monumental, and alive.

Laser

Soft verticals and a rain of light over the piece. Open and breathable strokes.

Fire

Audio

The music resolves in harmony. Calm water, luminous strings, and a chirimía to close.
