A new edition of SIGGRAPH is coming up this year with cutting-edge technology in computer graphics as well as heterogeneous computing and parallel processing with GPUs in latest years. As always, Khronos Group will host a Birds of a Feather event which will feature OpenCL, OpenGL, COLLADA and their various high quality open standards.
We at CMSoft look forward to meeting all the OpenCL community in the OpenCL BOF. See you in Anaheim!
We are very proud to be part of the newly created Khronos Chapters Brazil, a group supported by OpenGL and OpenCL spec developer Khronos Group.
The main focus of this Chapter will be usage of open standards for heterogeneous computing and computer graphics to enhance software industry competitiveness.
We're tentatively scheduling the first Chapter meeting to September/2013 in a date to be defined. If you are interested in networking with OpenCL/OpenGL developers in Brazil please
In the age of information, where huge amounts of data is available in the most diverse formats such as text, pictures, movies and audio and in a myriad of applications such as the Web itself, Facebook, Linkedin, Instagram, retrieving the most useful information is still a challenge.
The topic is closely related to parallel processing insofar as lots of computing power is necessary to fulfill queries whose complexity doesn't cease to increase. It would not come as a surprise to see servers resort to GPU-powered OpenCL solutions for improved performance in the near future.
The topic has raised interest in the corporate world: the Wall Street Journal published two very interesting articles about the theme:
The new Kinect SDK 1.7 features a very interesting tool: hand detection including open and closed hands (grip). However, the documentation for how to use the WPF controls or even how to set up and handle hand interaction events is quite poor, especially without using a KinectRegion.
We at CMSoft bring you a very basic sample demonstration to show how to handle Kinect open/close hand interactions. We show how to use C# to implement IInteractionClient to create the InteractionStream and handle the InteractionFrameReady event.
In this example, we demonstrate how to track positions and grips of left and right hands from 2 users. The Labels move and change color as users grip.
We're working to develop hand-controlled presentation software and 3D interaction with virtual worlds, stay tuned! Also feel free to comment or ask questions in our forum.
Interactive technologies have become extremely important in a world where busy users demand intuitive devices which demand little to no learning time. In this modern scenario, tablets have emerged with their easy-to-use touchscreens, gaming consoles have been successfully exploring movement controls (Wii, PS3 eye, Kinect) and augmented reality has started to emerge as a viable technology.
However, implementation of intelligent systems using devices such as the Kinect usually involves real-time processing of data from multiple sensors (RGB camera, depth camera, audio, accelerometers). This task can be achieved using OpenCL to harness the processing power of multicore GPUs and CPUs.
CMSoft brings you a tutorial on how to create a C# framework to capture Microsoft Kinect sensor data and transfer it to an OpenCL GPU Device, thus enabling the development of software that can potentially process Kinect data hundreds of times faster when compared to pure CPU processing.
In the results we show two OpenGL textured quads which are used to display RGB and depth information acquired from a Kinect sensor. Notice that there is a full false coloring procedure which includes highlighting players detected by Kinect.
