vvvv gamma Fundamentals

What Is vvvv gamma

vvvv gamma is a visual programming environment for .NET 8. It combines node-based patching with C# code generation, targeting Stride (3D engine) and .NET APIs. Programs are built by connecting nodes with links in a visual editor.

vvvv is a live programming environment — programs run continuously while you build them. Both visual patch edits and C# code changes take effect immediately without restarting. vvvv compiles C# source files itself via Roslyn into in-memory assemblies on every save.

Document Structure

• .vl files — vvvv gamma documents (XML-based, version controlled)
• Each document contains Patches (visual programs) and Definitions (types, operations)
• Documents can reference NuGet packages and other .vl files
• The Patch Explorer shows the document's type hierarchy
