Kirpi

Visual Programming Tool

Kirpi is a visual programming tool allowing to build and execute graphs of connected tasks,
where each node is C++ code.

Kirpi comes with ready-made applications allowing you to build and execute graphs, and provides an API and UI components that you can integrate into your own applications or plug-ins (eg. Maya, usdview, etc.).

Kirpi uses just-in-time (JIT) compilation and execution of C++ code on the fly.
Compiled code is efficient, debuggable and can be multithreaded.

Live Programming

  • Use built-in graph nodes or create your own.
  • Create dataflow by connecting nodes.
  • Create and edit nested subgraphs.
  • Set graph input values.
  • Execute and experiment!

Efficient Workflow

  • Live editing.
  • View code modifications, revert changes.
  • Self-documenting graph nodes.
  • Integrated profiling.
  • One-click vectorization.
  • Generate nodes from existing C++ functions.
  • Easy integration into any development environment (IDE, text editor, CMake).

Maximum Performance

  • Full C++.
  • Just-in-time (JIT) compilation.
  • Powered by LLVM and Clang.
  • Automatic parallelization.
  • Easy use of external APIs.

Seamless Integration

Kirpi comes with ready-made applications, but also provides an API and UI components that you can use to integrate it into your own applications and plug-ins. Here it is used in a Maya plug-in:

  • A graph is incorporated into a standard Maya dependency node.
  • Users edit the graph directly in Maya.
  • Users connect the graph's inputs by dragging and dropping Maya objects from the outliner.
  • The graph's input values are exposed in Maya's attribute editor.

USD Integration

Kirpi provides a customizable user interface for editing graphs.

Sticky Notes

Use sticky notes to make your graph self-documenting.

Backdrops

Use backdrops to group together related nodes, document them and manipulate them more easily.

Dark Theme

Kirpi's graph editor comes with two themes: light and dark. Just select the theme you want from the View menu.

Controller Window

Use Controller Window to test a graph interactively.

  • The Controller Window has a widget for each input and output.
  • Modify an input. Outputs are computed automatically.
  • Choose the widget you want for each input/output.
  • Implement your own widgets as plug-ins.
