This dataset is the focus of our blog post, How to Remove Shape from a Complex Surface. In the post we show how to use the tools in OmniSurf3D to tame a difficult surface and accurately measure features despite the complicated, underlying surface. Measured via GelSight Mobile. Data source: Asist. Prof. Alp Eren Şahin and … Read more
A quality cast iron pan is a great cooking surface that can last for generations. This dataset shows the surface of a new Lodge cast iron pan, which is shown under the Zygo ZeGage microscope, below. The cast iron is a fairly coarse surface. Looking at statistics for the dataset we can see that the … Read more
Is a non-stick pan surface slippery because it’s smooth? This dataset shows the surface of a Ninja Foodi Never-Stick pan. The surface is extremely durable, even against metal utensils, but will not stick. So, is it slippery because it’s smooth? Not even close! The Sq value is over 6 µm, which is on par with … Read more
How can you tell where a crack will form? It’s particularly difficult for a surface such as this one, with complex texture consisting of machining marks from various operations. Perhaps we would look for the deepest scratches (the blue areas in the image above) to predict where cracking may occur. However, cracks tend to form … Read more
This pair of datasets (Unworn and Worn) provides an excellent, close-to-home example of micro-wear. The measurements are from the worn and unworn areas of the space bar on a computer keyboard. The wear has not completely removed the texture, but it is quite noticeable in this image. The differences will appear dramatically in amplitude parameters … Read more

This dataset is featured in our video, OmniSurf3D Surface Editor Tool. When missing or errant data features are too big or too isolated to filter out, the Surface Editor Tool lets you selectively repair the data interactively. This data includes several sharp peaks and deep valleys that skew the real data. The video shows … Read more
This is a sample of regular, household tissue paper. Compare the image above to the image of printer paper, also in this library: They look very similar, right? But if you look at the z-axes of both plots, the vertical scale of the tissue paper is almost 10 times larger. When you display basic height … Read more
This dataset shows a washer surface with a “ding” that is a certain leak path. To display this data appropriately, turn off data filling (Analysis > Pre-Processing > Missing Data Filling= None), then remove a plane (Analysis >Geometry/Form > Plane). This is an excellent dataset for working with morphological filters in OmniSurf3D. Choose Tools > … Read more
Metal ruler. In OmniSurf3D, display the Wavelength Content Graph. When you drag the crosshair across the tick marks the strong 0.5 mm period will produce a tall spike in the Wavelength Content graph (we should hope so, or this would not be a very good ruler!) OmniSurf3D Hint: hold down the ALT key while … Read more
Sometimes it can be fun to explore the surfaces of everyday items…such as this switch from a Roku remote control. The data includes an image overlay, which gives a more realistic view of the data. In OmniSurf3D you can toggle the overlay on by clicking the Camera toolbar button, and toggle it off by clicking … Read more
This data shows the grooves of a stereo, vinyl LP record. The z-axis (heights) in surface data are commonly exaggerated in order to show detail. In OmniSurf3D choose View > Make 1:1 Aspect Ratio to see a truer representation of the slope of the groove walls. The song, by the way, is from an Arthur … Read more
