AECKit Visualizer

A VS Code extension that provides a custom 3D geometry viewer for .viz.json files.

Features

• 3D Wireframe Viewer — Opens .viz.json files in an interactive 3D viewer powered by Three.js instead of the default text editor.
• 2D / 3D Toggle — Switch between a top-down 2D plan view and a full 3D perspective.
• Plane Selection — In 2D mode, snap the camera to the XY, XZ, or YZ plane.
• Auto-Rotate — Optional auto-rotation in 3D mode with a single click to toggle.
• Live Updates — Edit the raw JSON in a split editor and see changes reflected in the 3D viewer in real time.

.viz.json Format

A .viz.json file is a standard JSON file that describes wireframe geometry using vertices and edges:

{
  "type": "wireframe",
  "vertices": [
    [0, 0, 0],
    [5, 0, 0],
    [5, 5, 0],
    [0, 5, 0]
  ],
  "edges": [
    [0, 1], [1, 2], [2, 3], [3, 0]
  ]
}

Field	Description
type	Currently supports "wireframe"
vertices	Array of [x, y, z] coordinate triples
edges	Array of [startIndex, endIndex] pairs referencing vertices

Usage

1. Install the extension.
2. Open any file with the .viz.json extension.
3. The 3D viewer opens automatically. To view the raw JSON alongside, split the editor (Cmd+\) and use Reopen Editor With... → Text Editor on the second pane.

Requirements

• VS Code 1.80.0 or later (or any compatible fork such as the Antigravity IDE)
