During a presentation at CEDEC in Japan, Sony Computer Entertainment revealed the features of the PS4 SDK 2.0, released to support the features of the console’s 2.0 firmware and to provide exciting new tech that game developers can use.
Below you can read a summary of the presentation (as reported by the Japanese website PC Watch), and our translation of all the slides for your perusual.
Support for Share Play, themes, ShareFactory and YouTube upload was introduced:
Image recognition and tracking features have been added with libDepth and Vision Library. libDepth makes use of the two lenses of the PlayStation camera to precisely track the distance of an object from the camera itself. Processing is done on the software level as the camera does not have the hardware chip included in Kinect.
Since using the CPU for the processing would slow down the software, thanks to libDepth it’s performed by the GPU. This compresses the processing time to only 1.5 milliseconds, which is roughly 1/10 of a frame at 60 FPS.
The AR Dynamic Lighting (which we saw a few months ago) has also been implemented. It introduces the ability to add realistic shading to augmented reality images.
It detects the intensity, position and estimated color of light sources in real life, allowing the console to create a natural AR image instead of one that sticks out like a sore thumb on the background because it isn’t correctly lit and shaded.
This is normally very difficult, so a simple algorithm has been implemented. The light sources are calculated by dividing the floor in a 3X3 grid, and then comparing the weighed averages of light intensity and color on each portion. In order to facilitate the calculation, the player uses a flashlight.
