A SWEEP-PLANE ALGORITHM FOR THE SIMPLIFICATION OF 3D BUILDING MODELS IN THE APPLICATION SCENARIO OF WIND SIMULATIONS
3D City models Automated Processing BRep
2018/11/9
As the number of virtual 3D city models is steadily increasing, so are the possible applications that take advantage of them. 3D models can be used for applications that range from simple graphic visu...
Researchers from North Carolina State University and the University of Delaware have developed an algorithm that can quickly and accurately reconstruct hyperspectral images using less data. The images...
While 3-D printers have become relatively cheap and available, 3-D scanners have lagged well behind. Now an algorithm developed by Brown University researchers may help bring high-quality 3-D scanning...
