![]() In Poland, the basic digital elevation model is based on a 1 m × 1 m mesh. storage of original measurement data, while in the GRID model, elevations at nodal points are mostly assigned interpolated values. GRID and TIN digital elevation modelsĮach of these models has specific advantages and disadvantages which determine their applications. TIN - model based on an irregular triangle mesh.įigure 1. GRID - model based on a regular square mesh Generally, there are two basic types of DEM based on different geometric structures: It uses an interpolation algorithm to calculate the elevation at any point of a surface covered by the constructed model. The Digital Elevation Model (DEM) is a discrete (point-based) representation of land surface elevation. Detailed Control Network Database (BDSOG).Database of General Geographic Objects (BDOO).National Register of Geographical Names.I have been using World Machine since version 1.25 and haven't found anything else that can compete for ease of use, versatility and stunning results. Rebecca Shearin, Senior Environment Artist, Electronic Arts This saves a bundle of time and with results that look more detailed and professional. World Machine works well with our proprietary terrain editor in that we can not only create height maps, but alphas for our terrain paint layers as well. Kenny Lammers, Technical Art Director, Microsoft Games Studio i would recommend this to any development studio that needs very realistic terrains, quickly! Its erosion filters are the best I have seen but also give a lot of control over the final look. ![]() World machine gives us the power to create very realistic terrains in a short amount of time. World Machine handled all of that beautifully. We needed a very large landscape and wanted something natural-looking but with enough control that we could place canyons and hills exactly where needed. World Machine was instrumental in creating the terrain for our Supersonic Sled demo. I have used World Machine on a number of film projects and find it an invaluable asset for environment creation. Jordan Edell, Senior Artist Specular Interactive A must have tool for any environmental artist. The feature set and work flow get better with each release. World Machine has allowed me to quickly and efficiently create massive game areas both terrestrial and otherwise. ![]()
