Table 4 Comparative analysis of surface and volume rendering techniques
Criteria | Surface rendering | Volume rendering |
|---|---|---|
Algorithm features | Retains only the external surface; internal details are lost | Utilizes opacity to reveal internal hierarchical structures |
Reconstruction quality | Clear but lacks pathological details | Retains overall details and structural complexity |
Running time | Fast | Slow |
Major deficiency | Insufficient edge extraction leads to blurriness | Prone to noise overlap |
Usage scenario | Suitable for scenarios requiring basic structural details | Ideal for detailed internal structure analysis |
