Abstract
Disclosed are apparatuses, systems, and techniques to render images depicting light interacting with media that have volume attenuation, using optimized spectral rendering that emulates rendering of the media in tristimulus color rendering schemes.
Claims20
A method of image rendering, the method comprising:
- identifying, in a first digital image rendered using an RGB color rendering scheme (CRS):
- a first depiction of a light prior to an interaction with a medium, and
- a second depiction of the light after the interaction with the medium;
- identifying, using the first digital image, one or more parameters characterizing the interaction of the light with the medium in a spectral CRS, the one or more parameters corresponding to an attenuation of one or more properties of the light propagating through the medium;
- and
- rendering, using the spectral CRS and the one or more parameters, a second digital image comprising the medium.
3 more elements
A system comprising:
- a memory device;
- and
- one or more processing devices, communicatively coupled to the memory device, to:
- identify, in a first digital image rendered using an RGB color rendering scheme (CRS):
- a first depiction of a light prior to an interaction with a medium, and
- a second depiction of the light after the interaction with the medium;
- identify, using the first digital image, one or more parameters characterizing the interaction of the light with the medium in a spectral CRS, the one or more parameters corresponding to an attenuation of one or more properties of the light propagating through the medium;
- and
- render, using the spectral CRS and the one or more parameters, a second digital image comprising the medium.
6 more elements
A non-transitory computer-readable medium storing instructions thereon, wherein the instructions, when executed by a processing device, cause the processing device to:
- identify, in a first digital image rendered using an RGB color rendering scheme (CRS):
- a first depiction of a light prior to an interaction with a medium, and
- a second depiction of the light after the interaction with the medium;
- identify, using the first digital image, one or more parameters characterizing the interaction of the light with the medium in a spectral CRS, the one or more parameters corresponding to an attenuation of one or more properties of the light propagating through the medium;
- and
- render, using the spectral CRS and the one or more parameters, a second digital image comprising the medium.
