This dataset includes a wear region on a spherical surface. Typically it would be challenging to measure the depth of this wear scar, because it blends into the overall curvature of the sphere. But the Wear Analysis tool in OmniSurf3D lets you precisely define reference and wear regions, to calculate key parameters such as wear … Read more
A lot of engineering goes into a soda can. This dataset shows the ridges in the can lid that let you open it with one finger—but that keep the can from bursting before it gets to you! We put a can under an Alicona optical 3D measurement system to have a look. The data shown … Read more
Mountain Hardware rain jackets are really soft and impressively waterproof. If you zoom in on this rain jacket/shell material, you can see the differences in the woven material in each direction (i.e., the “warp” and “weft”). This dataset has an image overlay stored with it—click the camera icon in the OmniSurf3D toolbar to view the … Read more
A collection of stones can be a good “macro” analogy for micro texture. The dataset was created with a 3D scanner. As with the marbles in this dataset, a 3D measurement tends to capture the full dimensions of each rock in the field of view, while a 2D slice through the data will likely miss … Read more
A bowl of marbles is a good “macro” analogy for micro texture. The dataset was created with a 3D scanner. In the 3D measurement data, we can see enough of most of the marbles to estimate their radii (try it with a circular mask in OmniSurf3D). If you cut a 2D slice through the data, … Read more
We recently acquired three model “LM6708” tapered roller bearing assemblies from different manufacturers. We decided to have a look at how their surfaces compared, and differed, right out of the box. This dataset is the Timken bearing, which has a micro-finished, crosshatched surface. Setting the vertical scales equal to each other makes it easier to … Read more
