On the fly hardware based interdigitation

A method of mapping a source image into a resultant autostereoscopic image, comprising:

• computing view numbers based on locations of pixels on a screen where the resultant autostereoscopic image is to be displayed, wherein view numbers comprise one value for each sub-pixel component of the source image;
• mapping pixel locations from multiple perspective views of the source image to the resultant autostereoscopic image using the view numbers;
• and
• extracting one subpixel component from each pixel location to represent color for the pixel in the resultant image.

An apparatus for interdigitizing an autostereoscopic source image to a screen comprising a plurality of pixels having sub-pixels and sub-pixel components, comprising:

• a computer configured to:
• generate a texture memory coordinate at each pixel location on the screen of the source image;
• calculate screen pixel location based on the texture memory coordinate of each pixel;
• compute view numbers based on screen pixel location, wherein view numbers comprise one value for each sub-pixel component;
• and
• extract one subpixel component from each proportional pixel location to represent color for the pixel in a resultant image.

A method of mapping a source image into a resultant autostereoscopic image, comprising:

• scaling the source image to form a scaled image;
• pixel shading the scaled image to form a pixel shaded image;
• and
• mapping pixel locations from multiple perspective views of the shaded image to the resultant autostereoscopic image, said mapping occurring at a pixel level of a computing device.
