Q92 / 100
What distinguishes "physically based rendering" (PBR) material models from earlier ad hoc shading models such as classic Phong?
Correct! Well done.
Incorrect.
The correct answer is D) PBR models ground their parameters in measurable physical properties and enforce energy conservation, producing consistent, realistic results across varying lighting conditions
D
Correct Answer
PBR models ground their parameters in measurable physical properties and enforce energy conservation, producing consistent, realistic results across varying lighting conditions
Explanation
PBR shading grounds material parameters — such as roughness and metallicity — in measurable physical quantities and enforces energy conservation, so materials look correct and consistent across different lighting environments, unlike older empirically tuned models.
