Classification: CPC H  G | IPC G  H

Claim 0:
1. A method comprising:
receiving image data defining a texture of an image and depth data for the image for display on a spatial light modulator (SLM) device;
generating, based on the image data, a plurality of folded focal planes matrices, wherein each folded focal plane matrix defines pixel values to be rendered by the SLM device;
for each respective pixel matrix of the plurality of folded focal planes matrices:
preprocessing pixel values in the respective folded focal pixel plane matrix to generate a respective preprocessed matrix, wherein the respective preprocessed matrix clusters together pixel values of the respective folded focal plane matrix based on the depth data for the image;

generating a plurality of phase functions for a spatial light modulator of the SLM device, based on a plurality of the preprocessed matrices;
configuring the spatial light modulator of the SLM device in accordance with the generated phase functions; and
providing the plurality of the preprocessed matrices as input to the configured spatial light modulator of the SLM device to generate for display a 3D representation of the received image data.
