Hi,

I am creating 2D projections of a 3D object by shining a light source
through it. I want projections at various angles and therefore, I rotate
the object to get different projections. The projections look good. My
question is on the kind of interpolation that POV applies while creating
the projection, i.e. when in taking a projection of ab object from a
non-orthogonal views, you get non-integer values of pixels; what and how
does POV interpolate those non-integer pixel values? To their nearest
neighbor?
