| 1. Overall Visualization Goal: Does the result match the ground truth isosurface rendering of the vortex scalar field? | |
| 2. Isosurface Structure: Does the isosurface show the same vortex structure and topology as the ground truth? | |
| 3. Surface Appearance: Does the surface color and shading appear similar to the ground truth? | |
| 4. Visualization Clarity: Are the vortex features clearly visible and comparable to the ground truth? | |
