GE 8651831G1 roughness specimens have been (historically) very popular in the measurement of surface texture. They show up in a lot of places… in documents and standard operating procedures, as well as for sale on eBay and industrial supply resellers. Measured via Zygo ZeGage Plus (10x) Data source: Digital Metrology
Surface texture is everywhere! In this dataset we take a 3D look at the iconic OREO cookie. While this surface may be interesting purely for the fun of it, it also demonstrates some challenges in terms of surface texture segmentation and feature extraction. Have a look for yourself by downloading the data and taking it … Read more
Can a surface be engineered for cooking? This HexClad Hybrid pan has a uniquely textured, multi-material surface. Its distinctive, hexagon pattern is evident in this dataset. This is another example of a surface that’s intended to be slippery (non-stick), yet it has a significant roughness with a pattern of peaks that are around 40 µm … Read more
Pickleball has become an incredibly popular sport in recent years. The texture of a pickleball paddle’s face is designed to create spin and control. This Garyce paddle face has a “Carbon Abrasion Surface (Cas)” with many sharp spikes. Compare this with the Vufoxt paddle also in the Surface Library. The Vufoxt paddle has an average … Read more
Pickleball has become an incredibly popular sport in recent years. The texture of a pickleball paddle’s face is designed to create spin and control. This Vufoxt paddle with a fiberglass face has a relatively smooth, random texture, while other paddles offer more complex and intricate textures. Compare this with the Garyce paddle also in the … Read more
This series of fish scales shows the many variations in morphology between fish species. The splitfin flashlight fish has highly ornamented scales with many spines on their surface. This image also shows roughness on the surface of the tail, as well as the higher-height lateral line canal that runs down the body. For this dataset, … Read more
This series of fish scales shows the many variations in morphology between fish species. The Ozark Bass is a native North American fish that has large ctenoid scales, which have very tiny spines on the edge pointed towards the tail. These small spines are typical of many species of fishes. For this dataset, a 4th … Read more
This series of fish scales shows the many variations in morphology between fish species. The Dusky Smooth-Hound is a shark, meaning it has tiny scales (called placoid scales or denticles). These features have complex, 3D shapes and create a surface made of their crowns which protrude above the skin. The crowns often have posterior points … Read more
This series of fish scales shows the many variations in morphology between fish species. The Black Nox Angelfish is a tropical coral reef fish that has large scales with very long spines that point posteriorly, giving the surface a ridged appearance. This fish even has these scales on parts of their fins, such as the … Read more
This series of fish scales shows the many variations in morphology between fish species. The American Shad is native to North America and migrates from salt to freshwater to breed in the spring. This species has large crenate scales, where the scale extends into weak protrusions (not quite spines) along its posterior edge. For this … Read more
This dataset is featured in our article, Analyzing additive surfaces with directional filtering. The small particles of partially-melted power are challenging to quantify. The striped pattern created by the additive manufacturing process makes the particles difficult to isolate. Directional filters—a standard feature of OmniSurf3D software—make it possible to suppress the ridges while retaining the features … Read more
In applications such as high performance diesel and some racing engines, an even more extremely plateaued surface is required. In these cases, the plateaued texture described above is pushed to more extreme limits. The valley texture is created by an even rougher honing process, creating deeper valleys that are spaced farther apart. The plateaus are … Read more
