8. OMA CD New WI – 3DCAPI Background
Andrew Min-gyu Han, Dongseo Univ. ©2013 All rights reserved. 8
• Many kinds of AI technologies are used to create or
convert 2D image to 3D model and are developing as
converting engines of on-line services.
– There are needs to get 3D contents from original 2D images
without using complex off-line tools and 3D modeling expert.
• 3D printer service is going popular due to its price going
down
– It bring us that 2D image is needed to convert to 3D image
• In the professional area, Game Services need to convert 2D
to 3D
– Mostly, their initial image is 2D but working image in game is 3D.
It means they have need to convert 2D to 3D during developing
phase
• Therefore, making 3DCAPI will provide convenient and
effective environments to developers including game area.

9. OMA CD New WI – 3DCAPI Use Cases
Andrew Min-gyu Han, Dongseo Univ. ©2013 All rights reserved. 9
• Service discovery: Request information to 3DCAPI
Server for getting service list
• Service connecting: Request service connecting from
user to 3DCAPI Server
• File transfer: Request file transfer to 3DCAPI Server
and receive the results
• Setting attributes: Setting creating options to 3DCAPI
Server
• Snap shot: Getting snap shot image of current
progress of converting
• File receive: Get the created file from 3DCAPI Server
• 3D Printing: Request 3D printing to DWAPI-3DP
enabler

11. Other WIs of OMA – LwM2M Introduction
Andrew Min-gyu Han, Dongseo Univ. ©2013 All rights reserved. 11
• OMA recommends utilization of
LwM2M for both data plane (data
reporting and device actuation)
as well as device management
due to benefits such as:
– Increased bandwidth efficiency
based on COAP bandwidth
optimization
– Transport-agnostic design that
supports
– UDP, TCP, SMS
– Developer toolkit for application
development
– DTLS-based security based on
CoAP (IETF)
– Low power client foot print
designed for battery constrained
devices
