Latest Patents

One of Zhdan's latest patents introduces advanced denoising techniques suitable for addressing recurrent blurs. The method elaborates on generating frames for virtual environments, where the filter radius for a pixel is dynamically determined by the number of successfully accumulated frames related to that pixel. To improve the effective sample count, the patent discusses employing ray-traced samples from a lower resolution version of a ray-traced render. Furthermore, the technique incorporates parallax to manage accumulation speed, as well as specific angles from the view vector corresponding to the pixel. Importantly, the dimensions of the filter can be adjusted based on the angle of the view vector, effectively elongating reflections under glancing angles according to the reflected specular lobe associated with each pixel.
