Open CASCADE is a suite for 3D surface and solid modeling, visualization, data exchange and rapid application development.

It is an excellent platform for development of numerical simulation software including CAD/CAM/CAE, AEC and GIS, as well as PDM applications. It includes C++ components for 3D surface and solid modeling, visualization, data exchange and rapid application development.

 Open CASCADE 6.9.0

FAQ, Forum, Open CASCADE notes

Selected Reviews:

Features include:

  • Components for:
    • 3D surface and solid modeling
    • Visualization
    • Data exchange
    • Rapid application development
  • Foundation Classes provide a variety of general-purpose services such as: primitive types, strings and various types of quantities, automated management of heap memory, exception handling, classes for manipulating aggregates of data, math tools etc
  • Modelling Data supplies data structures to represent 2D and 3D geometric models.These services are organized in the following libraries: 2D geometry, 3D geometry, geometry Utilities, topology
  • The Modelling Algorithms module groups together a range of topological algorithms used in modelling. Along with these tools, it is possible to find the geometric algorithms which they call
  • The Data Exchange classes provide services that allow Open CASCADE applications to exchange data with other software applications using the following interfaces: STEP AP203 AP214, IGES (it is also possible to import and export using some simpler vector data format such as VRML and BRep boundary representation)
  • For visualizing data structures, Open CASCADE provides ready-to-use algorithms which create graphic presentations from geometric models. These data structures may be used with the viewers supplied, and can be customized to take into account the specificity of your application
  • The Open Cascade Application Framework provides modelling services, aiming to connect user data, even non-geometric , to parametric geometric models. It also provides further functionalities for storing and editing the history of a work session, and not only its results. This approach is embedded into an automatic mechanism for document and application generation, called application template
  • Dynamic clipping of shaded objects by arbitrary planes, with cross-section visualized by capping algorithm
  • Support of GLSL programs
  • Ray tracing mode of display of shaded objects in OCCT viewer providing high-quality image (including sharp shadows, correct transparency, reflections)
  • Official support of Intel compiler, Visual Studio 2013, and Mac OS X 10.9 Mavericks
