Modules

GoTools functionality is distributed across the following GoTools modules.

• gotools-core. A few key modules are used by almost all the others; these have been grouped together in GoTools Core.
  • geometry: Classes and functionality for representing, storing and manipulating parameterized geometrical objects.
  • creators: Functionality for generating curves and surfaces by approximation, blending, etc.
  • tesselator: Functionality for making tesselations of geometry entities.
  • utils: General, low-level functionality.
• compositemodel. Representation, as one unit, of a surface set, including topological entities and operations on a set of surfaces.
• implicitization. Approximation of spline curves and surfaces by implicitly defined algebraic entities.
• igeslib. Read from and write to the Initial Graphics Exchange Specification (IGES) format.
• intersections. An object oriented library for finding intersections of geometric objects like spline curves and surfaces. The library handles singular surfaces and singular and near singular intersections.
• isogeometric_model. Tools related to isogeometric analysis. Spline surfaces and volumes.
• lrsplines2D. Classes and tools for locally refineable spline (LR-spline) surfaces.
• lrsplines3D. Classes and tools for locally refineable spline (LR-spline) volumes.
• parametrization. Compute reasonable parametrizations for discrete geometrical objects.
• qualitymodule. A set of tools to check the quality of CAD models.
• topology. Adjacency analysis for surface sets.
• trivariate. Spline volumes and elementary volumes, including some creation methods.
• trivariatemodel. A volume model including topology and some operations on the model.
• viewlib. Contains the application goview, which is a utility to support visualization of curves, surfaces, point clouds and line clouds. The application goview_vol_and_lr visualizes LR-spline surfaces and parametric volumes, the latter by showing their boundary surfaces.

In addition GoTools depends on the following libraries, which are included for convenience:

• SISL: SINTEF's spline library, available with GPL license.
• TTL: SINTEF's generic triangulation library, available with GPL license.
• newmat: Robert Davies' library for matrix operations, available with a permissive license.
