# Evaluation
1. **Chamfer Distance (CD)**: Measures the geometric discrepancy between the predicted mesh and the ground-truth mesh, reflecting the overall reconstruction accuracy.
2. **Edge Chamfer Distance (ECD)**: Evaluates the geometric similarity between the edges of the reconstructed mesh and those of the ground-truth mesh, serving as an indicator of edge sharpness and structural fidelity.
3. **Normal Consistency (NC)**: Assesses the alignment between surface normals of the predicted mesh and the ground-truth mesh, indicating the consistency of local surface orientation.
4. **V_Ratio**: Defined as the ratio between the number of vertices in the predicted mesh and that of the ground-truth mesh, reflecting changes in geometric complexity.
5. **F_Ratio**: Defined as the ratio between the number of faces in the predicted mesh and that of the ground-truth mesh, indicating variations in mesh resolution.
