| Abstract | One problem in subdivision surfaces is that the number of meshes growsquicklyaftereverysubdivisionstep. Thenumberofmeshesofthesubdivi- sionsurfaceisusuallyhugeandtheschemeisdi-culttomanipulate. Subdivision schemesarecostintensiveathigherlevelsofsubdivision. Inthispaper,weintro- duceanadaptivesubdivision schemeforsubdivision surfacesbasedontriangular meshes. This schemeworkswith the new subdivision rules and the biggest angle between the normal vectors of adjacent faces of a vertex is considered as error estimation and termed CA. The regular subdivision process is modifled to stop at the ∞at areas, so we can represent surfaces with lower cost when compared with those obtained by regularsubdivision schemes. In our scheme,wetakecare of the T-junction (cracking) problem and propose our solution. We compare our methodsforvarioustriangularmeshesand presentourresults. |
