What is NACK3D

NACK3D is a mobile application designed to capture real-world surfaces and convert them into physically based rendering (PBR) materials.

Using advanced image analysis techniques, the application extracts detailed surface information from a minimal number of images and reconstructs texture maps used in modern 3D rendering workflows.

The goal of NACK3D is to make material scanning fast, simple, and accessible, allowing artists and developers to create realistic textures directly from their smartphone.


Core Technology

NACK3D is based on a custom surface analysis pipeline that reconstructs material properties from photographic input.

Instead of relying on large photogrammetry datasets or specialized scanning hardware, the system analyzes lighting interaction with the surface to estimate structural and visual properties of the material.

This allows the application to generate multiple PBR texture maps from a very small number of source images.

The resulting materials can be used directly in modern rendering pipelines.


Generated PBR Maps

NACK3D produces several texture maps commonly used in physically based rendering workflows:

Albedo Map
 Represents the pure color of the material without lighting information.

Normal Map
 Encodes surface direction and microstructure, allowing render engines to simulate fine geometric detail.

Depth Map
 Represents height information of the surface.

Roughness Map
 Controls how smooth or rough the material appears when light interacts with it.

Specular Map
 Defines reflective properties of the surface.

These maps allow realistic rendering in modern 3D engines.


Advantages of NACK3D

Minimal Capture Requirements

Traditional material scanning often requires dozens of photographs or specialized equipment.
 NACK3D dramatically simplifies this process.


Fast Material Creation

The scanning workflow is optimized for speed, allowing users to capture and process materials quickly.


Mobile Workflow

NACK3D is designed to work directly on a smartphone, removing the need for complex scanning setups.


Real-World Material Capture

Instead of manually creating textures, users can capture real-world surfaces and transform them into digital materials.


Accessible Technology

NACK3D aims to make advanced material creation techniques available to independent artists, developers, and small studios.


Comparison with Traditional Methods

Photogrammetry

Photogrammetry requires large sets of images and significant processing time.

NACK3D focuses on fast material extraction with a minimal capture workflow.


Procedural Material Creation

Procedural tools require experience and time to design realistic materials.

NACK3D allows users to capture materials directly from the real world.


Applications

NACK3D materials can be used in many fields:


Future Development

The NACK3D project continues to evolve with improvements in:

The long-term vision is to make real-world material capture simple and widely accessible.
