Q82 / 100
In recursive (Whitted-style) ray tracing, what happens when a primary ray strikes a reflective or transparent surface?
Correct! Well done.
Incorrect.
The correct answer is D) New secondary rays — reflection and/or refraction rays — are spawned and traced recursively to determine the surface's final appearance
D
Correct Answer
New secondary rays — reflection and/or refraction rays — are spawned and traced recursively to determine the surface's final appearance
Explanation
Whitted-style ray tracing recursively spawns reflection and refraction rays at reflective or transparent surfaces, combining their contributions to render convincing mirrors, glass, and similar materials.
