Appearance Compensation in Volume Rendering
Can a volume that reproduces every external RGB view still have an incorrect density?
ProofPaper ↗
Key points
- We study this question in emission-absorption rendering with an independently parameterized, physically bounded effective source.
- We characterize the surviving density information with a shared spatial appearance field.
- Our third result constructs an exact physical SH2 ambiguity: central density doubles and relative density $L^2$ error exceeds $14.52%$, yet every external RGB ray is unchanged.
- The results show why rendering accuracy alone cannot certify density: recovery also depends on appearance capacity, spatial resolution and measurement design.
