Warpalizer is a professional warp and blend software application made by Univisual Technologies AB in Sweden, for use in simulators.
[1][2][3][4] Warpalizer can be used for projection on to surfaces that need image geometry correction (warping) to improve the image from the projector, on a cylindrical screen for example.
When used with multiple projectors Warpalizer uses edge blending to display the images from the different projectors without seams.
In 2013 Warpalizer was used in a 24 channel (projectors) excavator simulator,[5] based on 1 server and 24 clients.
