See-through Heatmaps

Three-dimensional heatmaps generated by HeatMiner® give you a whole new perspective to your data. Visualizations may reveal interesting phenomena you didn't expect to see or confirm a theory you already had. However, the natural downside of viewing 3d-objects as colored surfaces is that while watching one side you cannot see what's on the other side of the object. Thus, to see everything in the same view, you might want to see through the heatmap.

HeatMiner® supports two types of see-through heatmaps. Any heatmap can be viewed as a wire-frame heatmap or using 3d-contours as illustrated in the images below. These techniques can also be combined in the same view as will be seen in the next example.

Sometimes, the Truth is hidden deep inside the "cloud of observations" in which case rotating the view does not help at all. For example, the following image is generated using 3D tomography reconstruction data kindly provided by Eigenor Oy. The data is generated using Eigenor's high-end 3D tomography reconstruction software and comprises a million density observations within a 100x100x100 cube, given to HeatMiner as (x,y,z,d)-points. What you see in the picture is apparently a part of human hand or leg where colors indicate the density of the material. For example, those red circles in the middle of the first image are bones.

But wait a minute?! What are those purple spots near the right-side bone? Their density is remarkably higher than any surrounding material so they must be made of metal. Is there more of those? Are they two separate objects or one big? It would be really interesting to take a closer look, but how?


HeatMiner gives a solution. It allows you to set a specific value-of-interest to create a 3d-object viewing only the parts of the 3d-model where the the given value exists. In this tomography example, we can use the approximated density of the mystery object as the value we are interested of. In addition, we can visualize the outer surface as a see-through heatmap to get a better understanding of the whole. The resulting image reveals a really weird-looking metallic object that is probably put there in a surgery to fix a broken arm.


In case your browser supports Java and you have a fairly fast internet connection (to download over 10 Mb data), go and try rotating those tomography heatmaps as Java3D-applets!
