Raster volume dataset

The raster volume data records the values of the discrete lattices in a three-dimensional or multidimensional space, which is of great use in many fields such as computer graphics, geology, meteorology, etc., and can be used to simulate spatial communication signals strength, haze index, typhoon expression and so on.

Details of the physical spatial body can be displayed. The integrated distribution of a plurality of substances is displayed in a single image, and the isosurface is represented by the level of the opacity. 3D volume data can be seen as expansion of two-dimensional raster data in the three-dimensional space , so that the details of internal level of the feature can be shown.

By the Build volume function in SuperMap iDesktop, the raster volume dataset can be generated based on one or more 2D raster dataset; by the Create cache function it can generate the cache for it (*.scvo). At present, there are two ways to display a raster volume dataset in a three-dimensional scene. One is to load the dataset directly into the scene to express the data information, such as typhoon; the other is to rely on other layers to express the data , which needs to further generate the cache, such as communication signals, haze intensity.
