Here's a visualization of global winds and precipitations on September 1st, 2019 (when [Hurricane Dorian](https://tinyurl.com/y3jewqqt) was hovering over the Bahamas, off the coast of Florida).

* Created in Python (using Matplotlib, NetCDF4, Scipy and Numpy modules)
* Public wind and precipitation data from the [NCEP/NCAR Reanalysis](https://tinyurl.com/y6mfqr6f)
* Wind particles colored according to speed (using Matplotlib "inferno" colormap)
* Rain particles scattered according to the precipitation rate

The seamless-loop effect was achieved by periodically spawning the particles at their initial location on a time range greater than the animation, and subsampling this time range before export. This effect was further enhanced by fading each particle's color to black at their birth and death, and using the "Additive" opacity in Sketchfab material settings to hide black points.

*PS: for Python enthusiasts, I've uploaded a [script to preview point cloud animations locally](https://tinyurl.com/yhyuuqev) !*

This is an OEM leather racing seat used for tunning purposes. These shapes are very difficult to model properly as small variations can make a big difference in the comfort.

This is a great example of how peel 3d can be used in engineering. This component was scanned directly, without any preparation, we simply put a few targets in the back of the seat to improve tracking.  This scan would be perfect to keep as a reference for competitive analysis

Coffin of the Pharaoh Akenaten in the Egyptian Museum, Cairo, Egypt.

This coffin was recovered from a tomb in the Valley of the Kings in what has been designated Tomb KV55.  The tomb was discovered by Edward R. Ayrton in 1907 while working for the wealthy American Theodore M. Davis.  The tomb has been controversial since it's discovery, originally being designated the burial of Queen Tiye.  It has now been shown through DNA analysis that the remains found in the tomb are those of Akenaten himself.  The DNA has further demonstrated that Akhenaten was the father of Tutankhamen (King Tut).
The face of the coffin and the name in the cartouche have been deliberately removed in an attempt to condemn the “heretic” pharaoh in the afterlife and erase his memory.

Information on the tomb can be found [here](https://en.wikipedia.org/wiki/KV55).  A scan of another artifact from the tomb can be seen [here](https://skfb.ly/6PoHS).

Created using 138 photographs (Canon EOS Rebel T5i) using Metashape 1.3.

This is a laser scan of a Great White Shark jaw which was originally reported as coming from an 11 metre-long (36 feet)  shark, though subsequent analysis by the Museum estimates it at about 7.5 metres (25 feet) –  still a very large fish! 
The specimen demonstrates the incredible rows of spare  teeth that Great Whites have lined up inside their jaw. If a tooth is lost the  next one in line just folds up to take its place.
The specimen was used for public engagement for many years and has suffered as a result. This is a preliminary scan and we will be rescanning it with the aim of 3D printing a high quality replica for outreach.

Sandalwood, lacquer, and gold Chinese Amoghasiddhi Buddha, 1403 - 1424 CE, now in the collection of the Minneapolis Institute of Art.

From the sculpture's description on artsmia.org:

*'Amoghasiddhi is one of a group of five buddhas that embody five distinct types of wisdom and are thus sometimes called the “Five Wisdom Buddhas.” Of the five, who are believed to occupy the four cardinal directions and an immovable central direction, Amoghasiddhi occupies the northern position. He is an embodiment of the “Wisdom of Unrestricted Activity,” which enables one to save living beings on the path toward salvation using individualized means. Amoghasiddhi’s emblem, the double thunderbolt (vishvavajra), decorates the bottom of this sculpture... X-ray analysis has revealed what appear to be a roll of paper, a small bead or pearl, and a glass vial within a compartment inside this small statue.'*

High-detail 3D scan of an aluminum mountain bike front fork, created for accurate geometry reference and reverse engineering workflows.

The side surfaces have been automatically closed, and openings are present around the center section. These areas were intentionally left unmodeled, as they were not required for the reverse engineering of the specific fork component this scan was created for.

This approach ensures an efficient and clean dataset while preserving all critical geometric features needed for analysis, inspection, and downstream engineering use.

Suitable for:
• Reverse engineering
• Mechanical and industrial design
• Bicycle component analysis
• Reference and visualization purposes

Captured from a real-world object using 3D scanning and photogrammetry techniques.

**Pteranodon ignifalcis: A Breakthrough in Pterosaur Pigmentation**

In 2025, paleontologist Dr. Celeste Navarro led a multidisciplinary team in the Flaming Cliffs region of Mongolia, uncovering a remarkably preserved pterosaur specimen. Named *Pteranodon ignifalcis*—“Fire-Sickle Wing”—this Late Cretaceous flyer exhibited elongated cranial crests, clawed feet, and pigment-bearing integument with iridescent orange and teal hues.

Spectroscopic analysis revealed nanostructures consistent with structural coloration, marking the first confirmed evidence of iridescence in pterosaurs. The find suggests that visual signaling may have played a role in mating or territorial behavior, challenging prior assumptions of muted coloration in aerial reptiles. *P. ignifalcis* reshapes our understanding of pterosaur ecology, offering new insight into the evolution of flight, display, and sensory adaptation in prehistoric skies.

**Triceratops ignifrons: A Landmark Ceratopsid Discovery in Alberta**

In 2022, paleontologist Dr. Miriam Solano uncovered a striking ceratopsid specimen in the Horseshoe Canyon Formation of Alberta, Canada. Named *Triceratops ignifrons*—“Fire-Frilled Three-Horned Face”—this quadrupedal herbivore measured over 9 meters in length and featured an unusually elaborate frill with spiked margins and preserved pigment structures.

Spectroscopic analysis revealed traces of structural coloration, suggesting vivid blue, orange, and red hues across its frill and flanks. This challenges prior assumptions that ceratopsids relied solely on size and horn morphology for display. The discovery of *T. ignifrons* provides compelling evidence for visual signaling in herbivorous dinosaurs and deepens our understanding of social behavior and predator deterrence in Late Cretaceous ecosystems.

**New Theropod Species Unveiled: Tyrannovenator ignicolor**

In 2023, paleontologist Dr. Rafael Kim and his team unearthed a striking theropod specimen in the Kaiparowits Plateau of southern Utah. Named *Tyrannovenator ignicolor*—“Flame-Colored Tyrant Hunter”—this mid-sized predator exhibits unprecedented preservation of pigment structures and dermal ornamentation. Measuring roughly 7 meters long, it features prominent cranial crests and spine-like projections along its back, suggesting a role in visual display or intimidation.

Microscopic analysis revealed melanosome patterns consistent with iridescent and carotenoid-rich coloration, marking the first strong evidence of multi-hue signaling in apex predators. The discovery challenges assumptions about camouflage in large theropods and opens new avenues in the study of dinosaur behavior, ecology, and evolution. *T. ignicolor* stands as a vivid reminder that prehistoric life may have been far more colorful, and complex, than previously imagined.

This model was obtained by applying advanced photogrammetry technologies and cutting edge techniques currently not applied to this field that have allowed me to recreate previously unattainable models like Harbin, Yunxian 2 and now HLD-6. This model represents a reconstruction of the HLD-6 cranium from the Hualongdong paleoanthropological site in Dongzhi County, Anhui Province, China.

The HLD-6 individual lived during the late Middle Pleistocene, approximately 300,000 years ago. Stratigraphic and geochronological studies place the Hualongdong hominin assemblage between roughly 331–275 thousand years ago.

This digital reconstruction was created using published anatomical descriptions and visual references from the study “Craniofacial reconstruction and morphological analysis of the HLD-6 skull” (Acta Anthropologica Sinica, 2025) and scaled using cranial measurements from the supplementary dataset of “The phylogenetic position of the Yunxian cranium elucidates the origin of Homo longi and the Denisovans.”

This 3D model documents the preserved stem assembly of the 17th-century Dutch fluyt (fluitschip) Double Dutch (NCN 34303), discovered in 2022 in the intertidal zone of the Wadden Sea near Kornwerderzand by Stichting Archeos Fryslân. The wreck (31m x 6m) was investigated through a series of diving expeditions between 2023 and 2025. Based on constructional characteristics, associated artefacts, and dendrochronological analysis of sampled timbers, the vessel has been dated to around 1680. The stem assembly constitutes an important diagnostic component for the reconstruction of the bow structure and supports the interpretation of the wreck as a Dutch fluyt of approximately 120 Amsterdam feet in length.
