Modification of algorithm in order to prevent violation of angular and curvature deflection condition for smooth intervals of curve. Modification of algorithm for calculation of maximal deflection in command crvtpoints, crvpoints (CR25649) Elementary bug fixing in algorithm GCPnts_UniformDeflection.gxx Modification of test cases in order to set new reference parameters of shape triangulations Some tests: bugs modalg_2 bug397 mesh standard_incmesh C7, V3 mesh standard_incmesh_parallel C7, V3 mesh standard_mesh C7, V3 mesh standard_shading V3 were modified by TODO with reference bug 27226, because some problems in meshing algorithm (package BRepMesh) were discovered when tessellation of edges was changed. These problems cannot be solved by modification of GCPnts_TangentialDeflection algorithm. New issue #27226 was created, see bugtracker for details. Correction of test data Test case for issue #27108 Modification of algorithm for improving performance Correction of test cases
