1. Ray tracing faces challenges due to noise in image simulations.
🥇92 00:32
Noise in images results from incomplete light ray estimations, requiring extensive simulation time to reduce inaccuracies.
- Millions of light rays are needed to estimate light behavior accurately.
- Noise filtering techniques exist but may take time to produce clear images.
- Decades of research have improved ray tracing, but challenges persist.
2. New collaboration by University of Utah and NVIDIA enhances ray tracing capabilities.
🥇96 03:08
The collaboration introduces advancements like lower frequency noise, improved antialiasing, increased information extraction, and better resolution of light sources.
- Lower frequency noise aids denoising processes.
- 25 times more information extracted per light path compared to previous techniques.
- Improved resolution of bokeh light sources.
3. Challenges remain with the new ray tracing technique despite significant improvements.
🥈85 04:43
Concerns include generalization to motion blur, limitations with pixel filters for sharp still images, and slightly longer frame processing times.
- Uncertainty about performance with motion blur.
- Issues with pixel filters for super sharp still images.
- Slight increase in frame processing time compared to previous methods.
