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 26):
A non-rasterized image streaming system that uses ray tracing samples, comprising a processor configured to:\n obtain a plurality of ray tracing samples, each ray tracing sample of said plurality of ray tracing samples comprising\n a scrambled ray direction associated with a ray in a three-dimensional model of a scene, or a sample location corresponding to an intersection of said scrambled ray direction with said three-dimensional model of a scene, wherein said scrambled ray direction is derived from an original ray direction; and \n a sample color corresponding to said intersection; \n apply one or more compositing operations to modify said plurality said plurality of ray tracing samples, without obtaining or generating a rasterized image comprising a plurality of pixels, and without generating said original ray direction; compress said plurality of ray tracing samples; 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, wherein said network quality comprises a bandwidth of said network connection; and \n a desired stream quality associated with said each receiving device; \n wherein\n a first device information associated with a first receiving device of said plurality of receiving devices comprises one or more of\n a first display resolution; \n a first network quality; and \n a first desired stream quality; \n \n a second device information associated with a second receiving device of said plurality of receiving devices comprises one or more of\n a second display resolution; \n a second network quality; and \n a second desired stream quality; \n \n and\n said first display resolution comprises more pixels than said second display resolution; or \n said first network quality is higher than said second network quality; or \n said first desired stream quality is higher than said second desired stream quality; or \n any combination thereof; \n \n \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 said rasterized image comprising said 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 a size of said stream content associated with said first receiving device is larger than a size of said stream content associated with said second 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; wherein\n each receiving device of said plurality of receiving devices is configured to\n transform said ray tracing samples in said stream content received by said each receiving device into a corresponding plurality of unscrambled ray tracing samples, wherein each unscrambled ray tracing sample of said plurality of unscrambled ray tracing samples comprises\n said sample color; and \n said original ray direction or a sample location corresponding to said original ray direction; and, \n \n generate said rasterized image based on said plurality of unscrambled ray tracing samples.
