PK_ERROR_code_t PK_SURF_make_curves_isocline ( --- received arguments --- PK_SURF_t surf, --- surf to search for isoclines PK_UVBOX_t uvbox, --- surf parameter box PK_VECTOR1_t direction, --- isocline direction double angle, --- isocline angle double tolerance, --- accuracy for representing curves --- returned arguments --- int *const n_curves, --- number of isocline curves (>= 0) PK_CURVE_t **const curves --- isocline curves ) This function creates isocline curves on the given surface. NOTE: This function is deprecated and has been superseded by PK_SURF_make_cus_isocline. The isocline is specified by a 'direction' and an 'angle'. The function may, at times, have to use approximate geometry. For such cases, 'tolerance' specifies an upper bound on the distance by which a point on the actual geometry may deviate from its ideal position. While the function will usually satisfy this constraint, it is not guaranteed. The extent of the returned 'curves' will be sufficient, at least, to include all that part of any isocline curve which enters the 'uvbox'. As a corollary, any or all of the extent of a returned curve may lie outside the uvbox. The number of isocline curves created is returned as 'n_curves', and the curves themselves as 'curves'. If the given 'surf' belongs to a part, then the created curves will become construction curves of that part, otherwise they will become orphan curves in the current partition.Generated on: Fri, 04 Oct 2024 12:22:34 GMT
