Basic Principle
By showing independent images to each eye, it is possible to create
a sense of depth. (binocular parallax)
Display Display Display

on the screen (zero depth) in front of the screen behind the screen

Note: This technology requires a certain distance and viewing angle to achieve the optimum 3D effect.
Also, it works only in one orientation, e.g. in landscape mode but not in portrait mode.

16. REAL3D SDK HANDS-ON
• Introduction to Real3D SDK
• API usage
• Frame composition and configurations
• Source code example
16
17. LG Real3D SDK
• Works on the Android Platform.
• Enables developers to implement Real 3D applications & contents.
• Provides a Real3D API.
• Provides a new Real3D emulator (anaglyphic 3D).
17
18. Installing the LG Real3D SDK
LG Real3D SDK is available as :
Standalone Third party Add-ons.
http://developer.lgmobile.com http://developer.lgmobile.com/sdk/andr
oid/repository.xml
18
19. Real3D API
To view 3D images in 3D, a separate image has
to be delivered to each eye.
Using the Real3D API you can create 3D content without
worrying about the used display-technology.
The Real3D API will merge all the drawn information into L R
separated left/right images.
The phone will render the final 3D-image in the format
required by the display-technology.
19
20. Frame Buffer Composition
Real3D surface 2D surface • Real3D surface is defined and
waits for end of frame rendering
into the surface.
Surface flinger
• When rendering is finished, surface
flinger will compose the final image
for the frame buffer, based on
Frame Buffer enumeration of 3D_TYPE and
3D_ORDER
Hardware Abstraction Layer • Hardware Abstraction Layer will
convert the image into the format
required by the screen.
i.e. for a Column-Barrier 3D-LCD
Final Image
the Frame buffer will contain an
interleaved image of scene.
20
21. Real3D API :Image processing
• 3D Images are in the Side-by-Side
format.
• The side-by-Side format encodes
left & right perspective image data
in a single image frame.
• Images in the Real3D surface & 2D
surface are merged by the surface
Flinger into the display frame buffer.
• The resulting image is shown on
the 3D LCD panel by HAL
display(Hardware Abstraction
Layer).
21
22. Surface Orientation and Image Order
API allows for multiple formats of S3D:
3D Surface Types Image Order
REAL3D_TYPE_SS REAL3D_ORDER_LR L R
REAL3D_TYPE_TB REAL3D_ORDER_RL R L
• Other configurations are also possible, but industry-recommendation is
Side-by-Side, in LR order
22
23. API Usage / Initialization
// Create Real3DInfo class instance and define surface format.
Real3DInfo mR3DInfo = new Real3DInfo(true, REAL3D_TYPE_SS,
REAL3D_ORDER_LR);
// Create Real3D object instance, and pass in a surface holder.
Real3D mReal3D = new Real3D( mSurfaceView.getHolder() )
// Pass the surface format to the Real3D object.
mReal3D.setReal3DInfo( mR3DInfo );
23
24. OpenGL Applications
• Initialization of Real3D OpenGL is same as other OpenGL applications
• Scene rendering involves more steps
• Two images of a scene need to be created and rendered into the
correct part of the surface (L or R)
• Typically two step process for each eye
• Setup viewport / camera
• Render frame
