VISION

Appearance is much more than just color or a picture.

It’s the complete visual sensation through which an object is perceived.

AXF FORMAT

FUNCTIONALITYREQUIREMENTS

FOUNDATIONSTRUCTURE

AXF FILE FORMAT – FUNCTIONALITY

• Describes appearance

• Is device-neutral, platform-independent

• Makes appearance exchangeable and transportable

• Supports encryption of proprietary data

• Allows material certification

• Connects to real-world materials and SKUs

APPEARANCE FILE FORMAT

• Scalable

• General

– Extensible

– Self-describing

• Compatible with normal workflows

• Secure

• Based on HDF5

• Binary

• Block accessible

• Extensible (XML style)

• Self-describing (XML style)

• Standard SVBRDF

• Supports block encryption

REQUIREMENTS ATTRIBUTES

CXF VS. AXF

Color eXchange Format Appearance eXchange Format

CxF AxF

Color Appearance – texture, gloss, surface micro-texture, and transparency

Developed in the early 2000s Newly developed

ISO 17972 It is our intent that AxF gets the same wide adoption as CxF

AxF is complimentary to the CxF format and is able to store CxF based color information
