This approach combines spectral upsampling with real-time rendering methods, highlighting usability in diverse contexts.
We present a real-time, physically-based rendering pipeline that enables the usage of traditional RGB textures for spectral rendering in real time contexts by leveraging preexisting spectral upsampling techniques for reflectances. We combined our approach with other techniques, such as real-time underwater rendering, in order to prove its extendability.
