Their staff have more ways to communicate with one another, and can do so in a targeted manner. Companies can easily make the most of being able to project onto any surface using their on-board graphics card. This way, the whole Windows desktop - and any Windows pro- grams - automatically adjust to curved projection screens. "That is why we took the decision to integrate the automatic calibration software straight into graphics cards' drivers. Time and cost escalate when users have to connect extra devices, and this also results in a delay in video display. To be able to project any type of content calls for special software and hardware tools, connected between the graphics card and the projector. Until now, this technology has been available only in combination with Fraunhofer FOKUS's media player, which is designed for specific media formats such as films, images, text or graphics. Integrating the software into graphics card drivers "Today, planetariums, theme parks and simulators use the `Projector auto-alignment' tool to guarantee an even picture on large contoured surfaces," says Schiewe. It then has all the information it needs to make auto- matic corrections to the calibration and brightness of the images. ![]() The software then uses image processing algorithms to calculate the current calibration of the images on the projection screen. To do this, cameras capture test images generated by the projectors. The solution came from Fraunhofer FOKUS's laboratories in Berlin, where researchers developed a piece of software that automatically calibrates images to match the projection screen. "As soon as the position of the projectors moved even slightly, we had to step in and make manual adjustments," recalls Schiewe. Initially, the only way this could be done was to calibrate manually. This requires Schiewe to recalibrate the images, which were originally intended for a flat screen. Projectors must be set up so that the images they project are of an equal brightness and suitable for a curved surface. Every piece has to slot in exactly with the others to get the right picture," explains Schiewe. Each of them projects a part of the image, parts which together form the whole. To get an even picture on a curved screen, each of the projectors must be precisely calibrated with one another. Manuel Schiewe, a FOKUS researcher who has dedicated a lot of time to the topic, is on hand to provide some answers. "Desktop warping" allows any Windows desktop display to be projected onto curved screens - just like in a planetarium.īut how exactly do you go about "warping" screens? Now, scientists from the Fraunhofer Institute for Open Communication Systems FOKUS in Berlin have joined forces with graphics card manufacturer NVIDIA to integrate the technology required to project images of this type using a standard PC graphics card. The biggest of these domed projection screens measure over 20 meters in diameter. In short, the perfect illusion - numerous projectors broadcasting a recreated version of the actual night sky onto the huge dome of the planetarium. The glowing band of the Milky Way is clear in the sky, leaving you with the impression of actually being enveloped within it. You can reach out and touch the Big Dipper and all around you are multitudes of twinkling stars. Intel's Xeon and process node roadmap remain on schedule.It's almost as if you were weightless. Development of Lancaster Sound has been discontinued in their Flex Series product family to instead accelerate development on Melville Sound. ![]() Rialto Bridge has been discontinued and thus Ponte Vecchio will be sticking around longer. Intel intends to have Falcon Shores ready in 2025 that is based on a chiplet architecture. Intel's next product in the Max Series GPU family is Falcon Shores. Intel is moving to a two-year cadence for data center GPUs. The key takeaways from Intel's Friday afternoon disclosure include: Prior details on the Intel Falcon Shores XPU Intel's Flex Series "Lancaster Sound" GPU has been canned to focus on its Melville Sound products instead. Intel previously pointed to a 2024 launch for the Falcon Shores XPU with CPU, GPU, and memory co-packaging in a chiplet design. Intel announced today it has cancelled Rialto Bridge and Lancaster Sound development while shifting its Max Series focus to their Falcon Shores XPU that is now set to ship in 2025.
