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.
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
- Install the extension.
- Open any file with the
.viz.json extension.
- 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)
