Transcript
Creating high-quality photorealistic materials for light transport simulations typically includes direct hands-on interaction with a principled shader. This means that the user has to tweak a large number of material properties by hand, and has to wait for a new image of it to be rendered after each interaction. This requires a fair bit expertise a... Read More
Questions & Answers
Q: How does the learning-based system enhance the workflow of creating photorealistic materials?
The system recommends new materials to the user based on a small set of high-scoring samples, reducing the need for manual tweaking and rendering. This speeds up the process and allows for mass-scale material synthesis.
