API Reference ​

Links to VTK API documentation for all supported languages.

C++ API ​

The C++ API is the primary interface to VTK. Auto-generated documentation is available via Doxygen:

  • VTK Nightly Doxygen — Latest development API
  • Class hierarchy, method signatures, and inheritance diagrams
  • Search by class name or namespace

Python API ​

VTK Python wrappings mirror the C++ API closely:

  • All VTK classes are accessible from Python
  • Automatic type conversion for common types
  • NumPy integration for data arrays
  • Python-specific utilities in vtkmodules.util

CMake API ​

VTK provides CMake functions for building applications:

  • find_package(VTK) — Locate VTK installation
  • vtk_module_autoinit() — Configure module initialization
  • Module-based component selection
  • Custom module development

Conventions ​

  • Class names start with vtk prefix (e.g., vtkActor)
  • Set/Get methods for properties (e.g., SetColor(), GetColor())
  • Boolean methods use On/Off suffix (e.g., VisibilityOn(), VisibilityOff())
  • Factory methods via New() (C++) or class constructor (Python)
