Plinth

For the first detailed comparison, I want to start with the baseline: photogrammetry.

This object was captured with the Plinth iOS app using auto capture on a turntable.

133 photos
15 minute capture
Full processing time: 7:45
Post-adjustment in Plinth to tune the PBR materials

What photogrammetry gets right is that the result is tied to observed image data.

The geometry is reconstructed from many captured views of the actual object. Surface detail, proportions, visible damage, material variation, and object-specific irregularities are grounded in photographs of the real object.

That does not mean photogrammetry is perfect.

It still depends on capture quality, lighting, coverage, surface properties, and enough overlap between images. Reflective, translucent, very dark, or low-texture materials can still be difficult. Post-processing and material tuning also matter.

But for cultural heritage, this baseline is important because the workflow is evidence-based.

We can say what was captured.
We can inspect the source image set.
We can understand where the geometry came from.
We can distinguish reconstruction from adjustment.

That is the reference point I want to compare against when looking at AI-generated 3D outputs from TRELLIS.2 and Apple LiTo.

The question is not simply whether the result looks good.

It is whether the result can be traced back to the object.

Object from Museum Beelden aan Zee.

Earth Day is a day to celebrate our planet and all the wonderful things it has to offer. This year, Earth Day is a chance to focus on reducing our carbon emissions, in order to help combat the dangerous effects of climate change. Did you know that the art world emits more CO2 every year than the entire country of Austria—77 million tons to be exact? Join us to learn more about our efforts to reduce carbon emissions. 🌍

Art fairs “by their nature are inherently unsustainable,” said Heath Lowndes, the managing director of the Gallery Climate Coalition (GCC), an international group attempting to reduce the environmental impact of the industry. https://buff.ly/40GvaQk

Plinth is a proud member of the GCC and supports their initatives.

The online exhibition has become a new territory for most galleries, which, in response to the challenge, have expanded the boundaries of the usual white cube exhibition space to their individual exhibition needs.

Art is essential. It teaches students countless lessons: practice leads to excellence, small differences can have a big impact, collaboration leads to creativity. Art also teaches children that there are multiple ways to solve problems and that all problems can have more than one solution.
