Anaglyph maker (Stereogram)

👓 Qwen Any to Stereogram – ComfyUI Workflow

Created by Me – a filmmaker & AI workflow designer. This tool transforms any single image into a stereoscopic 3D stereogram – perfect for creating immersive 3D content, VR assets, or classic 3D viewing experiences. It generates multiple formats: Side‑by‑Side (SBS), Anaglyph (Red‑Cyan), Black‑&‑White Anaglyph, and standalone left/right eye views – all from one input image.

### 🧩 Overview

This workflow takes a 2D image, generates a left‑eye and right‑eye view using Qwen‑Image with a specialised Stereogram LoRA, then processes them into several stereoscopic formats:

- Side‑by‑Side (SBS) – for VR headsets, 3D TVs, or cross‑eye viewing.

- Anaglyph (Red‑Cyan) – for classic 3D glasses (colour and black‑&‑white variants).

- Separate left/right images – for further custom compositing.

The result is a believable 3D depth effect that works with standard 3D viewing methods.

### 1️⃣ Required Models & Prerequisites

Make sure these files are placed in your ComfyUI models/ folders:

| Folder | Required Files |

|--------|----------------|

| diffusion_models/ | qwen_image_edit_2509_fp8_e4m3fn.safetensors (or qwen_image_edit_2511_bf16) |

| loras/ | Qwen-Image-Edit-2509-Lightning-4steps-V1.0-bf16.safetensors <br> Create Stereogram - Qwen Edit 2509_(Make stereogram).safetensors |

| text_encoders/ | qwen_2.5_vl_7b_fp8_scaled.safetensors |

| vae/ | qwen_image_vae.safetensors |

> ⚠️ VRAM Requirement: ~8–10 GB recommended – the workflow uses Qwen‑Image with Lightning LoRA for fast 4‑step generation.

### 3️⃣ How It Works (2D → Stereogram in 5 Steps)

1. Load your image – any 2D image (portrait, landscape, concept art, etc.).

2. Generate left & right views – the image is passed through Qwen‑Image with the Stereogram LoRA to produce two slightly offset views (simulating binocular disparity).

3. Side‑by‑Side assembly – the left and right images are stitched together horizontally using ImageStitch to create a classic SBS stereogram.

4. Anaglyph creation – colour channels are merged (Red from left view, Cyan/Green+Blue from right view) to produce a red‑cyan anaglyph compatible with classic 3D glasses. A black‑&‑white variant is also generated by desaturating the image before channel merging.

5. Save all formats – multiple outputs are saved: SBS, left‑only, right‑only, colour anaglyph, half‑colour anaglyph, and B&W anaglyph – all with descriptive prefixes.

### 6️⃣ Advanced Settings (Optional)

- SEED – set a fixed seed for reproducible left/right view generation.

- Positive Prompt – customise the prompt to guide the stereogram generation (default: "Make stereogram").

- Negative Prompt – exclude unwanted elements (e.g., "low quality, bad anatomy...").

- Hue / Saturation / Brightness – the workflow includes adjustable color‑grading nodes (HSL/HSB) to fine‑tune the anaglyph output (e.g., adjust red‑cyan balance).

- Output Formats – you can choose which formats to save by connecting/disconnecting SaveImage nodes.

### 📦 Final Output

After running, you’ll get a set of stereogram files in your output folder:

- Qw_SBS_*.png – Side‑by‑Side format (ready for 3D TVs/VR).

- Qw_SBS_Left_*.png / Qw_SBS_Right_*.png – individual eye views.

- Qw_SBS_Anaglyph_Color_*.png – red‑cyan anaglyph (full colour).

- Qw_SBS_Anaglyph_Black&White_*.png – black‑&‑white anaglyph (often sharper and more comfortable for long viewing).

- Qw_SBS_Anaglyph_Half_*.png – a half‑colour variant.

Why I built this: As a filmmaker, I often work with 3D concepts, VR storyboards, or want to give clients a quick 3D preview of a scene. This workflow turns any 2D concept into a stereoscopic experience in seconds – no complex 3D software needed. It’s perfect for pre‑visualisation, VR content creation, or just having fun with 3D! I hope it brings a new dimension to your creative projects! 👓✨
