1. A system configured to modify a set of time ordered digital images comprising a computer configured to: associate a first mask as a first layer in memory of a computer with a translucent object in a first image; copy said first mask to create a second mask in said memory associated with a second image; move said second mask to a location of said translucent object in said second image; automatically reshape said second mask in memory with said computer to fit said translucent object in said second image based on underlying image data in said second image; accept input for at least one depth parameter and set said at least one depth parameter associated with said first mask said memory; apply said at least one depth parameter to said second image; generate a first pair of images for left eye viewing and right eye viewing respectively for said first image through ray tracing two or more layers comprising said first layer wherein said first layer and said two or more layers comprise depth values that may overlap in depth; generate a second pair of images for left eye viewing and right eye viewing respectively for said second image through said ray tracing.
