Introduction
Many projector installations benefit from combining several projectors into one larger and seamless image. When the projection screen is not perfectly flat or rotated at an angle, the image needs to be reshaped and adjusted to the irregular surface. Optoma Visual Suite is a professional software that provides an easy way to digitally adjust the images from different projectors, allowing users to create a single unified image, no matter of its size or shape.
• Warping
When projecting images onto a non-planar screen surface, such as a curved screen or an elliptical surface, the images become distorted. The Warp function allows you to perform grid point adjustment to accurately warp the projected image to matches the curve of the display surface with minimal performance impact.

• Blending
If you are projecting the images onto a large and irregular display surface, such as a building wall, a hemispherical dome, and a cylinder, multiple projectors are required to expand the possibilities to alter the image shape and size. Using the Blending function, you can easily combine the images from several projectors into a single image, with the content spanning across the display surface. Also, with the blending features, you can stack two or more images on the same screen, creating one brighter image.

• Masking
In environmental projection, you might need to avoid projecting onto some objects or areas, such as the audiences, speakers, or set design elements on the stage. Using the Mask function, you can place a mask over those objects you want to avoid. Also, masking allows you to cover certain parts of the images, creating a special visual effect such as looking at a image through a window or balcony.

• Black Level
When several images are blended together, the overlapping area can become brighter than the rest of the image, especially when projecting dark images. This is because the merged region gets twice amount of the light. Black level function is designed to adjust the overall brightness of the blended image to achieve better uniformity in dark scenes.
