mikejuk writes "The OpenNI website, home to the widely used framework for 3D sensing, will be shut down in April. When, in November 2013, Apple bought PrimeSense for $350 million, people speculated how this would affect the Capri mobile technology but no mention was made of what would happen to OpenNI, the open source SDK most often used as an alternative to Microsoft's closed SDK for the Kinect. After Apple acquired PrimeSense, its website quickly shut, but the Developers link still points to Open NI. The status of OpenNI is a not-for-profit whose framework allows developers to create middleware and applications for a range of devices, including the Asus Xtion Pro. It claims to be a widely used community with over 100,000 active 3D developers."
