Printed material for stereoscopic viewing is fabricated by creating images
for the left eye and the right eye IL1 and IR1 for stereoscopic viewing,
performing correction processing to remove perspective of images in the
IL1 and IR1 at a base surface, creating images for the left eye and the
right eye IL2 and IR2, and performing anaglyph processing or the like,
based on the IL2 and IR2. An image IL for the left eye is created by
rendering a projection of each point of a graphic object onto a base
surface BS in a projection direction linking a viewpoint position for the
left eye VPL to each point of the graphic object OB, and an IMAGE IR FOR
THE RIGHT EYE is created by rendering a projection of each point of the
graphic object onto the base surface BS in a projection direction linking
a viewpoint position for the right eye VPL to each point of the graphic
object OB. Printed material for stereoscopic viewing is fabricated by
anaglyph processing or the like, based on the IL and IR.
