1 THE FUTURE OF MATERIAL COMMUNICATION VIA THE APPEARANCE EXCHANGE FORMAT AXF Dr. Marc Ellens EI 2017: MATERIAL APPEARANCE

2 APPEARANCE DISCUSSION ACQUISITION DEVICE AXF FORMAT ROADMAP VISION WHAT IS THIS ALL ABOUT?

3 WHAT IS APPEARANCE? Color Gloss Texture Transparency Translucency Appearance is much more than just color or a picture. It s the complete visual sensation through which an object is perceived.

4 TOTAL APPEARANCE CAPTURE IS THE DIGITIZATION OF MATERIALS WITH TRUE, FULL APPEARANCE MEASUREMENT Geometry Scene Context Material APPEARANCE Observer

5 INTRODUCTION: WHAT IS TOTAL APPEARANCE CAPTURE? FULL APPEARANCE MEASUREMENT TOTAL APPEARANCE CAPTURE IS THE DIGITIZATION OF MATERIALS WITH TRUE, FULL APPEARANCE MEASUREMENT ARTISTIC PROCESSES ARBITRARY RESULTS DEPENDING ON ARTISTIC SKILLS OF OPERATOR TYPICALLY OPTIMIZED FOR A SPECIFIC SCENE TEXTURE SCANNER PLAUSIBLE COLOR DECLINING ACCURACY WITH INCREASING MATERIAL COMPLEXITY PHYSICALLY CORRECT AS BASED ON MEASUREMENTS HIGH ACCURACY EVEN FOR COMPLEX MATERIALS SCENE INDEPENDENT Accuracy

13 FUNCTIONALITY REQUIREMENTS FOUNDATION STRUCTURE AXF FORMAT

14 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

15 APPEARANCE FILE FORMAT Scalable General Extensible Self-describing Compatible with normal workflows Secure REQUIREMENTS ATTRIBUTES Based on HDF5 Binary Block accessible Extensible (XML style) Self-describing (XML style) Standard SVBRDF Supports block encryption

16 CXF VS. AXF Color exchange Format Appearance exchange Format CxF Color Developed in the early 2000s ISO AxF Appearance texture, gloss, surface microtexture, and transparency Newly developed 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

17 AXF DETAILS AxF-Root ColorSpec DeviceSpec MaterialCollection Color space, primaries, illuminants, etc. Device information, acquisition properties Main data set for the material
