Figure 1: A scanned ceramic vase with a 5cm crack. Poisson reconstruction bridges it into a bulge. QSC healing closes it smoothly. Under simulated impact, QSC propagation extends the crack along natural stress lines, while FEM fails at real-time rates.
Cracks in surface meshes arise from two opposite sources: quicksurface cracked
All operations are local: ( O(1) ) per triangle split. Figure 1: A scanned ceramic vase with a 5cm crack
The key contribution is a — a sparse, dynamic half-edge structure that allows crack operations in O(log n) time per edge. Under simulated impact, QSC propagation extends the crack
If the cost of a full license is currently a barrier, there are legitimate ways to access the tools you need without resorting to piracy.
In the world of 3D reverse engineering, time is money. QuickSurface has established itself as a powerful, user-friendly solution for converting mesh data (STLs) into CAD models. However, the price tag of professional software often leads users to search for terms like
We build a ( G_B ) where nodes are boundary vertices, edges connect consecutive boundary edges. Using a spatial hash grid (cell size = average edge length), we find potential crack pairs ( (b_i, b_j) ) in O(1) expected time.
