In the example above both warp and blend are used to achieve a seamless, blended picture from three projectors illuminating on a curved screen.

When using multiple projectors to create a seamless image, the image where each projector overlaps will create a hotspot because this region gets twice the amount of light (shown above by the light grey shapes in the center).
Also notice the projected image shape warps because of the curved screen.

Warp point adjustment by manually moving marker points on the screen are used to modify the geometry so that the images match the curve or shape of the projection screen.
Blending is then used to duplicate the image to allow reduction in the increased brightness caused by the overlapped portion of the projectors. 

 

The video shows the basic use of AutoBlend but with manual point calibration (map on projector method).
This method is good if you have a large flight cockpit in front of the screen that would be too difficult to keep removing to recalibrate via a camera

This can also be an automated process via AutoBlend.
In this case one or more cameras are used to scan the screen creating an export file that Pixelwix software can import. 
AutoBlend can also create multiple frustrum view files for flight software and other simulation software.

This video shows the basic use of AutoBlend (map on camera method).
This method is good if you have no obstruction in front of the screen or for permanently installed cameras e.g. Pixelix IR tracking.

 

This video shows the end result from customers'own calibration using Pixelwix Evo Ultimate software for his flight simulation curved 270 degree screen.
