Using Nodos

Installing Nodos, building and running graphs, and managing the modules that provide nodes. This is the ground floor — if you are here to write a plugin, do this part first, then go to Developing for Nodos.

Pages are grouped by what you need from them.

Tutorials

Lessons. Guided from a known starting point to a working result, meant to be followed start to finish without deciding anything yourself.

  • Your first graph — install Nodos, open the editor, and build a graph that adds two numbers and shows the result. Introduces threads, sinks and pins, and why a graph needs an execution root at all. About 15 minutes, no C++.
  • Running an AI model — load an ONNX model, convert a texture into the tensor layout it wants, run inference on the GPU, and convert the result back. About 30 minutes, needs an AI bundle.

How-to guides

Recipes. One problem each, for someone who already knows what they want.

Reference

Descriptions of the machinery. Look things up here; these pages do not teach.

  • nodos CLI — every command of the workspace and package manager, including the authoring and publishing commands used in Developing for Nodos.
  • Launcher CLI — nosLauncher arguments, settings overrides, service addresses.

Explanation

Background. Read these when a behaviour surprises you.

  • Architecture — the processes that make up a running Nodos system and how they talk to each other. Explains why closing the editor does not stop your graph.
  • Scheduling and execution — why a graph needs threads and sinks, what recompiles when you edit, and in what order things run. Worth reading whether you write C++ or not.
