What are some advanced ray tracing techniques in C++?
Some advanced techniques include path tracing, photon mapping, and bidirectional path tracing. Would you like to know more about any specific technique?
Can you explain path tracing in detail?
Path tracing simulates the way light travels and interacts with surfaces. It traces paths from the camera to light sources, capturing complex lighting effects like reflections and refractions.
What are the performance considerations for path tracing?
Path tracing can be computationally intensive. Techniques like importance sampling and adaptive sampling can help optimize performance.
Are there any libraries in C++ for ray tracing?
Yes, libraries like PBRT (Physically Based Rendering Toolkit) and OpenRT provide frameworks for implementing ray tracing in C++.
