Key Functions
get_largest_connected_component(triangles, rounding_decimals=4)- Find largest connected component via vertex-based BFS adjacency with 4-decimal quantizationcompute_mesh_volume(triangles)- Volume via signed tetrahedron method: abs(sum(v1.(v2×v3)))/6.0convert_volume_mm3_to_cm3(volume_mm3)- Divide by 1000calculate_mass(volume_cm3, density_g_cm3)- Mass = Volume × Density
Usage
import sys
sys.path.insert(0, '/app/environment/skills/evo-mesh-geometry-analysis/scripts')
from utils import get_largest_connected_component, compute_mesh_volume, convert_volume_mm3_to_cm3, calculate_mass
largest = get_largest_connected_component(triangles)
vol_mm3 = compute_mesh_volume(largest)
vol_cm3 = convert_volume_mm3_to_cm3(vol_mm3)
mass = calculate_mass(vol_cm3, density)
Critical Details
- Vertex quantization: 4 decimal places
- Adjacency: vertex-based (share ANY vertex = connected)
- Volume formula: V = abs(Σ v1·(v2×v3)) / 6.0
- Unit conversion: mm³ / 1000 = cm³
