Adding Surfaces
Function Introduced:
Use the function
ProSurfacedataAlloc() to allocate memory for the surface data. Once the surface data is initialized, it will be appended to the interface data.
Initializing Surface Data
Functions Introduced:
Use the function
ProSurfacedataInit() to initialize the surface data structure.
The input arguments of this function are:
• Surface_type—Specifies the type of surface to be created. The types of surfaces are:
◦ PRO_SRF_PLANE—Plane
◦ PRO_SRF_CYL—Cylinder
◦ PRO_SRF_CONE—Cone
◦ PRO_SRF_TORUS—Torus
◦ PRO_SRF_COONS—Coons Patch
◦ PRO_SRF_SPL—Spline Surface
◦ PRO_SRF_FIL—Fillet Surface
◦ PRO_SRF_RUL—Ruled Surface
◦ PRO_SRF_REV—General Surface of Revolution
◦ PRO_SRF_TABCYL—Tabulated Cylinder
◦ PRO_SRF_B_SPL—B-spline surface
◦ PRO_SRF_FOREIGN—Foreign Surface
◦ PRO_SRF_CYL_SPL—Cylindrical Spline Surface
The type of the surface determines the function to be used to initialize the surface data structure.For example, if the type of surface to be created is
PRO_SRF_PLANE, then the function
ProPlanedataInit() should be used to initialize the surface data structure
• surf_uv_min—Specifies the minimum uv extents of the surface.
• surf_uv_max—Specifies the maximum uv extents of the surface.
• surf_orient—Specifies the orientation of the surface. By default the value is PRO_SURF_ORIENT_OUT
• p_surf_shape—The data containing the information about the shape of the surface.
• Surface_Id—Specifies a unique identifier of the Surface.
Depending on the shape of the surface, call one of the following functions to create the surface data structure
ProSurfaceshapedata and assign it to variable
p_surf_shape of function
ProSurfacedataInit(). Ensure that the function used to create the
ProSurfaceshapedata matches with the
ProSrftype value used in
ProSurfacedataInit().

Note:
|
Set the configuration option intf_in_keep_high_deg_bspl_srfs to YES to preserve the B-spline surfaces returned by ProBsplinesrfdataInit() in the ProIntData data structure. If this configuration option is not set, these surfaces are interpreted as spline surfaces. |
Refer to the
Geometry Representations appendix for more information on how to use the above functions.
|
Note:
|
PRO_TK_BSPL_UNSUITABLE_DEGREE
PRO_TK_BSPL_NON_STD_END_KNOTS
PRO_TK_BSPL_MULTI_INNER_KNOTS
They indicate that the geometry finally imported in is different from the geometry initially supplied to the above functions. The geometry is not rejected by the functions and is used to generate the ProSurfaceshapedata data structure.
