Description daveholland 2006-02-23 00:39:23 UTC 
Currently, there exists no feature in Impress that allows users to project a 
presentation onto a screen or wall from an arbitrary angle.  Some projectors 
have software that accomplishes this built-in, albeit at a price tag of 
thousands of dollars.  The idea would be to provide a menu item that lets the 
user specify two angles and a distance from the center of projection.  The 
software then runs some elementary linear algebra and skews the image so that 
when it is projected, the slide show fills the screen with no distortion.

This would probably involve modification of the vtk, in addition to the Impress 
application itself.

@daveholland: quite nice idea - that wouldn't even be too complicated to
implement (only the way to present an UI for this would be, I guess). As long as
we limit ourselves to affine transformations (strictly correct would be
perspective), this is almost for free when using the canvas for rendering.
