ON::object_type ON_PointGrid::ObjectType ( ) const
overridevirtual

Description: Useful for switch statements that need to differentiate between basic object types like points, curves, surfaces, and so on.

Returns: ON::object_type enum value.

Remarks: The default implementation of this virtual function returns ON::unknown_object_type

Reimplemented from ON_Object.

◆ Read()

bool ON_PointGrid::Read ( ON_BinaryArchive &  binary_archive)
overridevirtual

Description: Low level archive writing tool used by ON_BinaryArchive::ReadObject(). Parameters: binary_archive - archive to read from Returns: Returns true if the read is successful. Remarks: Use ON_BinaryArchive::ReadObject() to read objects. This Read() function should read the objects definition back into its data members.

The default implementation of this virtual function returns false and does nothing.

Reimplemented from ON_Object.

◆ Reverse()

bool ON_PointGrid::Reverse ( int  )

◆ SetPoint()

bool ON_PointGrid::SetPoint ( int  ,
int  ,
const ON_3dPoint &   
)

◆ SwapCoordinates()

bool ON_PointGrid::SwapCoordinates ( int  i,
int  j 
)
overridevirtual

Description: Swaps object coordinate values with indices i and j.

Parameters: i - [in] coordinate index j - [in] coordinate index

Remarks: The default implementation uses the virtual Transform() function to calculate the result. If you are creating an object where Transform() is slow, coordinate swapping will be frequently used, and coordinate swapping can be quickly accomplished, then override this function.

Example: 

     ON_Point point(7,8,9);
     point.SwapCoordinates(0,2);
     ///< point = (9,8,7)

Reimplemented from ON_Geometry.

◆ Transform()

bool ON_PointGrid::Transform ( const ON_Xform &  xform)
overridevirtual

Description: Transforms the object.

Parameters: xform - [in] transformation to apply to object. If xform.IsSimilarity() is zero, then you may want to call MakeSquishy() before calling Transform.

Remarks: When overriding this function, be sure to include a call to ON_Object::TransformUserData() which takes care of transforming any ON_UserData that may be attached to the object.

See Also: ON_Geometry::IsDeformable();

Remarks: Classes derived from ON_Geometry should call ON_Geometry::Transform() to handle user data transformations and then transform their definition.

Reimplemented from ON_Geometry.

◆ Transpose()

bool ON_PointGrid::Transpose ( )

transpose grid points

◆ Write()

bool ON_PointGrid::Write ( ON_BinaryArchive &  binary_archive) const
overridevirtual

Description: Low level archive writing tool used by ON_BinaryArchive::WriteObject(). Parameters: binary_archive - archive to write to Returns: Returns true if the write is successful. Remarks: Use ON_BinaryArchive::WriteObject() to write objects. This Write() function should just write the specific definition of this object. It should not write and any chunk typecode or length information.

The default implementation of this virtual function returns false and does nothing.

Reimplemented from ON_Object.
