PK_ERROR_code_t PK_BODY_create_sheet_circle ( --- received arguments --- double radius, --- radius of circle (>0) const PK_AXIS2_sf_t *basis_set, --- position and orientation (may be NULL) --- returned arguments --- PK_BODY_t *const body --- sheet body returned ) This function creates a circular sheet. Specific Errors: PK_ERROR_distance_le_0 radius <= zero In its local coordinate system, this function creates a circular sheet in the xy plane, centred at the origin, and of the given radius. basis_set positions and orientates the local coordinate system in the world coordinate system. If it is given as NULL, then the local and world coordinate systems are the same.
