Is useful in topography for "Digital Terrain Modeling" (DTM) by "Triangulated Irregular Network" (TIN), representation (by 3DPOLY, SPLINE or BLOCK entities) and editing (modify, delete or add) of 3D points, and for triangulation, isolines, cross sections, longitudinal profile, 2D entities (Line or PLine) projection over a DTM, conversion of a TIN to a regular grid of points and for conversion of existing isolines resulting from maps in points and then in TIN. It exists a modifiable library for codes and BLOCKs. The coordinates, the code and the position (in 3DPOLY or SPLINE) of the points can be modified interactively. You can represent the geological stratification resulting from drilling. You can calculates the volume and center of gravity of some bodies limited by 3DFACE entities. RCAD graphic core, distributed together with RTOPO, provides OpenGL real-time orbit, pan, zoom, shading and lighting.
Program system requirements: Graphic card with OpenGL hardware acceleration and 32-bit color depth, Windows XP and computer administrator account
New in this version: Can project 2D entities (Line or PLine) over a triangulation and can convert a triangulation to a regular grid
