Abstract:
Secure rendering system that creates ray tracing samples with obfuscated positions, so that images can only be viewed by an authorized consumer able to recover the sample positions. Obfuscation of ray directions is integrated into the rendering process, for example by incorporating encryption into a lens shader. The rendering system never stores or transmits an image without obfuscating positions, so even the rendering system cannot see the image it is rendering. Embodiments may use public key cryptography, so that encryption of sample positions is done with a public key, and only the owner of the secret private key can view the rendered image. Since keys are asymmetric, the rendering system cannot decrypt the obfuscated samples. Piracy of rendered images is therefore mitigated. Some compositing operations may be performed on the secure rendering output prior to decrypting sample positions; for example, colors may be modified globally or for selected objects.

Claim (Index 1):
A non-rasterized image streaming system that uses ray tracing samples, comprising a memory and a processor coupled with said memory wherein said processor is configured to:\n obtain a plurality of ray tracing samples, each ray tracing sample of said plurality of ray tracing samples comprising\n a ray direction associated with a ray in a three-dimensional model of a scene or a sample location corresponding to an intersection of said ray direction with said three-dimensional model of a scene; and \n a sample color corresponding to said intersection; \n obtain device information associated with each receiving device of a plurality of receiving devices, said device information comprising one or more of\n a display resolution of said each receiving device; \n a network quality of a network connection between said processor and said each receiving device; \n a desired stream quality associated with said each receiving device; \n transform said plurality of ray tracing samples into a stream content associated with each receiving device of said plurality of receiving devices, wherein\n said stream content associated with said each receiving device does not include a rasterized image comprising a plurality of pixels; \n said stream content associated with said each receiving device comprises said plurality of ray tracing samples or a subset of said plurality of ray tracing samples; and \n said stream content associated with said each receiving device is based on said plurality of ray tracing samples and on said device information that corresponds to said each receiving device; and, \n transmit said stream content associated with each receiving device of said plurality of receiving devices to said each receiving device over said network connection between said processor and said each receiving device.
