Boolean → curvature → clean quads
Boolean ops produce dense triangulated soup that's unusable downstream. HolyGrail reads the principal curvature directions of the boolean result and lays out a quad mesh aligned to them. Sharp edges retained, UVs transferred from the high-poly source, normals re-baked.
FIG. HG-01 · boolean → curvature field → curvature-aligned quad layout · principal directions · pole tracking · UDIM survives
▸ Why this works as a demo asset
Real-world candidate · profile helmet portrait — curvature flow visible across the chrome shell, the exact kind of dense triangulated surface HolyGrail rebuilds as principal-direction-aligned quads.
