Lennox “Dragon – What Perfect Feels Like”

Lennox’s “Dragon – What Perfect Feels Like” is a 2015 projection-mapped commercial for Lennox air conditioners that brings a fantastical dragon to a real suburban home. Visual effects company A52 created computer-generated animations that were projected directly onto the house, then shot using traditional filming methods — turning the practical location into a real-time, live CG experience captured in camera.

SCANable 3D scanned the house and built models from that capture, and provided consulting services for the projection mapping, giving A52 the precise geometry needed to align its animations perfectly with the architecture.

In projection mapping, the building is the screen

Most computer graphics are composited into a plate. Projection mapping inverts that: the animation is thrown onto a physical object and photographed, so the object’s surface is the display.

A display with the wrong shape distorts everything shown on it. If the digital model of the house is a few centimetres off at the gable, the projected image lands a few centimetres off too — and unlike a composite, there is no matte to nudge afterwards.

So the model has to be a measurement rather than an approximation. That is what 3D scanning the location provides.

Houses are never built exactly to drawing

Architectural plans describe intent. Buildings describe what the crew actually did that week.

Rooflines settle. Siding runs long. Window reveals sit deeper on one side than the other. Additions rarely align with the original structure, and nothing on site is quite as square as the elevation says it is. None of that matters until you try to project onto it.

A laser scan records the house as built, deviations included. Working from plans instead means discovering the discrepancies at night, on location, with a projector already rigged and a crew standing by.

Captured in camera means there is no second pass

Shooting projected animation practically buys something valuable: the light is real. It spills, wraps and bounces onto the lawn and the street because it is genuinely there.

The trade is that the effect is committed at the moment of exposure. There is no re-render, no version two, and no relighting in comp.

Everything that would normally be fixable in post has to be correct beforehand, which pushes the entire burden onto the survey, the alignment and the model. Measured geometry is what makes an in-camera approach safe enough to put on a schedule at all.

More advertising and brand work is in the portfolio, and the full service list covers the rest.
