ComfyUI Illusion & Pattern Nodes

ComfyUI Illusion & Pattern Nodes

This repository contains a collection of custom nodes for ComfyUI, designed for generating various patterns, optical illusions, and performing related image manipulations. All nodes are categorized under "illusion" in the ComfyUI menu.

Installation

1. Navigate to your ComfyUI custom_nodes directory:

   cd ComfyUI/custom_nodes/
   

2. Clone this repository:

   git clone https://github.com/orion4d/illusion_node.git
   

3. Restart ComfyUI.

The nodes should now be available in the "illusion" category when you right-click or use the "Add Node" menu.

• Key Features:
  • Takes a depth_map (grayscale image where brightness indicates depth) and a pattern image.
  • eye_separation_pixels: Simulates the distance between eyes projected onto the image plane, influencing the pattern period.
