DeltaVision - Pixel Motion Detection

🔼DeltaVision – Pixel Motion Detection

DeltaVision is a powerful post-processing effect for Unity URP that detects motion between pixels and transforms it into a fully customizable visual effect.

By comparing frames in real time, DeltaVision highlights moving pixels in your scene, allowing you to create stylized motion visuals, reactive VFX, and motion-based gameplay mechanics.

The effect is fully integrated with Unity’s Volume System, giving developers complete control over how motion detection behaves in their projects.

Whether you're creating experimental visuals, gameplay mechanics based on movement, or unique artistic effects, DeltaVision provides a flexible and easy-to-use solution.

✅ Compatibility

DeltaVision is fully compatible with:

• Unity 6000.3
• Unity 2023.2
• Unity 2022.3

It is designed specifically for the Universal Render Pipeline (URP) and integrates seamlessly with Unity’s rendering workflow.

🎨 Key Features

Real-Time Pixel Motion Detection

Detect motion directly from the rendered image by comparing pixel changes between frames. Highlight movement in your scene and turn it into a dynamic visual effect.

Full Unity Volume System Integration

DeltaVision works natively with Unity’s Volume System, allowing you to blend motion detection settings across different areas of your scene with smooth interpolation between profiles.

Fully Customizable Visual Output

Adjust how motion appears on screen with flexible controls including:

• Motion detection tolerance
• Motion color and background color
• Scene color blending
• Motion color intensity
• Motion highlighting and visualization

After Image Effect

Create beautiful motion trails using a built-in after-image system that accumulates frames over time.

Customize how the effect behaves with parameters such as:

• After image decay
• Brightness threshold
• Brightness falloff

This allows you to create anything from subtle persistence to dramatic motion trails.

Blur and Distortion Effects

Enhance motion visuals with optional stylized effects including:

• Configurable blur
• Texture-driven screen distortion
• Adjustable distortion strength and animation

Layer-Based Motion Filtering

Detect motion only where you want it by using camera layer filtering.

The asset includes a ready-to-use two-camera prefab setup that allows you to isolate motion detection to specific objects or layers in your scene.

🧪 Included Demo Scenes

DeltaVision includes several demo scenes designed to help you understand how the system works:

• A demonstration scene showing full-screen motion detection in action.Motion Detection Showcase
  
• Example of layer-based filtering where motion is detected only on selected objects.Filtered Motion Detection Scene
  
• Two simple game examples demonstrating how motion detection can be used for motion-based gameplay mechanics.Playable Game Demo Scenes

📁 Also Included

• Ready-to-use volume profiles
• Camera setup prefab for layer-filtered motion detection
• Example distortion textures
• Fully commented source code
