ComfyUI-Equirectangular-Strip

Custom nodes for ComfyUI to convert between equirectangular (360°) images and a strip of 6 cube faces (90° FOV each).

Nodes

360 → 6×90° Strip

Converts an equirectangular panorama into a horizontal strip of 6 perspective views:

• Front (0), Left (1), Back (2), Right (3), Top (4), Bottom (5)

Inputs:

• image: Equirectangular image
• face_size: Output size for each face (default: 512)
• order: Comma-separated face order (default: "0,1,2,3,4,5")
• flip_sides: Flip horizontal faces vertically (useful for person detection)

Outputs:

• strip: Horizontal strip image (width = face_size × 6)
• order: Pass-through for wiring to inverse node
• flip_sides: Pass-through for wiring to inverse node

6×90° Strip → 360

Converts a 6-face strip back to equirectangular projection.

Inputs:

• strip: The strip image
• width, height: Output equirectangular dimensions
• face_size: Size of each face in the strip
• order: Same order used during encoding
• flip_sides: Same setting used during encoding

Installation

Copy this folder to your ComfyUI custom_nodes directory.

Usage

1. Connect an equirectangular image to 360 → 6×90° Strip
2. Process the strip (e.g., apply effects, run detection)
3. Connect to 6×90° Strip → 360 to reconstruct
4. Wire order and flip_sides outputs to inputs for correct reconstruction
