Voxels are also useful in simulation techniques that require modeling of individual particles, as is the case of smart material simulation.īecause they can represent complex objects in reducible, discrete units (like particles), they can be incredibly powerful for simulating real world behaviour of complex objects. More broadly, scientists can use voxel-based modeling to visualize and measure the volume of anything from fluids to green spaces in urban centers. Geologists often use voxel modeling techniques to model geological features like terrain and elevation. For example, in Voxel-based morphometry, researchers can compare the differences in concentration of brain tissue using voxels. Most of our hardware is meant to render polygons - so high-resolution voxel objects can take a serious toll on current hardware.ĭespite not being ready for mainstream adoption, voxel modeling has a few very specific use-cases today.Ĭurrently, voxels are used in many scientific disciplines to quickly determine volumetric data. There are some promising attempts (like Atomontage, referenced above) - but all the other modeling methods listed above are still quicker and easier for truly complex designs.įurthermore, modern computers are simply not optimized to handle rendering voxels. In practice, however, there are no mainstream methods for easily building out complex, high-resolution objects using voxels. If you have a high enough density (or “resolution”) and the proper rendering techniques, you can use voxels to replicate real-world objects that would be impossible to differentiate from the real thing - in appearance and behavior. In theory, voxels are the perfect modeling technique for replicating reality.Īfter-all, our world is made of something akin to voxels (but they are much smaller, and we call them “sub-atomic particles”). Voxels are essentially 3D pixels, but instead of being squares, they are perfect cubes. Instead, you see words, pictures, and symbols that appear smooth. If you’re on a fairly new computer, you most likely can’t make any pixels out, because your display is “high-resolution.” These pixels are so tiny, and there are so many of them, that you can’t actually see them. Everything you see on your computer screen is made up of very small squares called “pixels.” Firstly - let’s examine what pixels actually are.
