GPU based warping for multi-channel display solutionsEVEN Composer is the core of the EVEN suite. Using EVEN Composer you can create seamless images from any number of projectors on any type of surface. Results of EVEN Composer can be used and integrated in any 3D application based on OpenGL or Microsoft DirectX. No additional hardware required, and by utilizing the GPU, the overhead on performance is minimal.
The warping engine in EVEN Composer takes care of the geometry correction image, resulting in a 100% perspective correct image. Start off by using some physical marker points on your projection screen; once these markers are transferred in the warping editor it is very easy to correctly map the image onto the projection surface. If necessary, EVEN Composer allows you to fine-tune it manually, using a spline mesh with arbitrary precision.
Edge blending and masking
Blend overlapping areas of 2, 3, or more projectors, with any shape, using the blending editor. The blending amount per projector is calculated automatically once the blend zones are defined in the editor. Using the masking editor you can mask off areas where you don’t want to project. Cut off parts of the projection that fall outside your screen or onto obstacles, to create an image that fits perfectly on your projection screen.
Color and intensity matching
Even if they are from the same brand and model, you may find differences in color or contrast between your projectors. This is no problem with EVEN Composer, as it provides you full control over gamma, color balance, brightness and contrast for each projector. And when your screen is curved, or if you project from a non-straight angle, a smart per-pixel brightness editor lets you remove intensity variations across the image.
Full multi-channel control
With EVEN Composer, you can create your calibration setup for an unlimited number of projectors. All projection channels can be controlled through the host application, which can run on a separate PC, for example a laptop. This allows you to quickly edit all channels at once, or focus on a single channel, all from just one computer.
Reliability and speed
With EVEN Composer you can save on expensive hardware because EVEN Composer is a software only solution. Not only does this reduce your cost of ownership, but also eliminates the extra risk of hardware failure that comes with hardware-based solutions. And because the EVEN software uses the power of modern GPUs to do its magic, you don’t have to worry about any noticable latency.
Use multiple outputs on a single pc
If your software supports it, you can easily use multiple channels from the graphics card, each with its own EVEN configuration. This allows you to further reduce costs, by cutting down the number of PCs in your rack.
