About Open Cascade

OpenCascade is organized in different modules (alphabetic order):

• ApplicationFramework
• DataExchange
• Draw
• FoundationClasses
• ModelingAlgorithms
• ModelingData
• Visualization

Each module contain a number of toolkits (TK). For example:

• FoundationClasses
  • tkernel
  • tkmath
  • …

Each toolkit contains a number of packages as seen for tkernel.

So OpenCascade is huge (beyond 7600 headers).
