    @arun If your work is related with terrain data then you can Please check following link qgis.spatialthoughts.com/2012/03/… & Most of the times QGIS is better than ArcGIS : )

In 3D rasters, with three spatial dimensions plus a data value dimension, the point elements are called voxels. GRASS GIS provides voxel operations. Map algebra tools are provided in r3.mapcalc.

If you are unfamiliar with how to set up QGIS to take advantage of these tools check out the QGIS GRASS Cookbook, or for a more visual tutorial see Setting Up A Working GRASS Environment in QGIS.
