We work with screens of all shapes and sizes, from compact 2m radius screens with stereo images to large 6m radius screens being fed by suitably large projectors. We’d be happy to talk through the numbers and options with you to suit your project. There’s more to it than just how big a room you have…
Many of our customers use 3, 5, 7 or 9 projection channels or 6, 10, 14 or 18 channels of 3D stereo projection. Field of view typically spans 180 to 230 degree on cylindrical projection screens, but you could project many 10’s of channels onto your screen to create huge resolution, stereo, wrap-around displays.
With the quality of warp and blend on offer, we no longer see any particular advantage to using a spherical screen, with its higher costs, over a cylindrical screen.
Warp & Blend – Hardware or Software
We work alongside all of the major warp & blend calibration products, both hardware and software solutions, to create a single, optically correct image. You can get automatic and semi-automatic calibration systems to ensure your multi-channel images are always perfectly aligned and beautifully blended, edge-over-edge. Our warp and blend is performed on the GPU as the image is rendered, removing the need for a warp & blend box in the video pipeline, further improving the performance of the video pipeline.
We don’t sell or recommend specific projector hardware, but we have worked on many graphics installations… The key specifications have to be high refresh rate (120Hz), low latency, high resolution (at least 1920×1200 per channel), high brightness (scaling with screen size) and superior colour reproduction. Most of the simulator grade projectors now offer automatic or semi-automatic colour matching routines for creating accurate “single image” outputs.
