How does this all apply to video games?

Well first…why do people play video games?
Engaging Storytelling

Game Personalization

Character Personalization

Asset Generation

Level / World Generation

Level / World Generation (LEGO)

3D Scanning with the RealSense SDK
PXCSenseManager *sm = PXCSenseManager::CreateInstance();
sm->Enable3DScan();
PXC3DScan* scanner = sm->Query3DScan();
sm->Init();

PXC3DScan::Configuration config = {};
config.mode = PXC3DScan::ScanningMode::OBJECT;
config.options = PXC3DScan::ReconstructionOption::TEXTURE;
config.startScan = true;
scanner->SetConfiguration(config);

while(sm->AcquireFrame() == PXC_STATUS_NO_ERROR)
{
PXCImage* scanImage = scanner->AcquirePreviewImage();
...
sm->ReleaseFrame();
}
scanner->Reconstruct(PXC3DScan::FileFormat::OBJ, “scan.obj”);

Game Personalization
Take ownership of your experience through custom content creation
• Character Personalization via Face / Head / Body Scanning
• Asset Generation via Object Scanning
• Level / World Generation via Environment Scanning

Game Socialization

Chat Heads
Level 0
Level 1
Level 2
Level 3
No Comms
Text Chat
Voice Chat
Video Chat

Segmented Streaming

BGS with the RealSense SDK
PXCSenseManager *sm = PXCSenseManager::CreateInstance();
sm->Enable3DSeg();
PXC3DSeg* seg = sm->Query3DSeg();

sm->EnableStream(STREAM_TYPE_COLOR, 1920, 1080, 30.0f);
sm->EnableStream(STREAM_TYPE_DEPTH, 640, 480, 30.0f);
seg->SetFrameSkipInterval(0);
sm->Init();

while(sm->AcquireFrame() == PXC_STATUS_NO_ERROR)
{
PXCImage* segImage = seg->AcquireSegmentedImage();
...
sm->ReleaseFrame();
}

Game Socialization
Enhance your social experience of playing video games.
Depth-Based Foreground / Background Segmentation
• See your teammates and/or competitors “floating heads” while you play together.
• Achieve green-screen style streaming without the large and expensive setup.

Next Steps for Intel
Refine the
implementatio
n and the
performance
of the SDK
Develop more
code samples
demonstrating
these use
cases
Integrate the
features of
the SDK
seamlessly
into popular
engines
Test these
experiences
with gamers to
perfect the
user
experience

Conclusion
RealSense Technology
can be used in many
different ways to
create fun, new gaming
experiences. Players are primed and
ready for something
new, and RealSense
can be a differentiator
for your next game.
Developing with a new
technology like
RealSense is a huge
challenge, but we can
overcome it by
working together.

Getting Involved
Get in touch with us! If you want to talk about adding RealSense capabilities to
your game or if you want more information, we would love to hear from you.
Order a RealSense Developer Kit and start playing with the SDK:
