GTGRID is a set of libraries that represent the core technology used for gridding and displays in GTEDIT. These libraries are a major development area for GTI. Over the last ten years these routines have been extensively restructured in order to make them easy to use in many different environments.

Features

• Dynamic Memory Management
  All major memory needs are acquired and released via standard memory management tools like MALLOC
• Surface Structure Composition
• Points
• Faults
• Boundary Polygon
  An encapsulation of a surface allows the application developer to manage multiple surfaces easily whether he is working in FORTRAN,C or C++

Multiple Interpolation Methods

For more information read our Technical Notes on Gridding. Several methods are supported that allow the developer to control how random points are mapped onto the grid nodes.

Outputs

• Polygons (Color fillable)
• Contour lines
• Annotated Contours
• Fault lines

In addition to the graphical components noted above, there are several service routines which allow the developer to retrieve components of a surface for his own use. These include getting a grid, a profile or a single z value.

The software is available for UNIX and LINUX platforms.
UPDATE! - GTGRID is also available for Windows .
