Detailed Description

Class NURBSSurface.

Description:

This class defines a dependent ruled surface. A ruled surface is generated from two curve sub-objects. It lets you use curves to design the two opposite borders of a surface. Methods are available to get/set the indices of the parent surface in the NURBSSet and the parent Ids and to set the surface normal matching state of the surfaces.

All methods of this class are implemented by the system.

Remarks

Constructor. The data members are initialized as follows:

mType = kNRuledSurface;
mpObject = NULL;
mpNSet = NULL;
for (int i = 0; i < 2; i++)
{
    mParentId[i] = 0;
    mParentIndex[i] = -1;
    mFlip[i] = FALSE;
    mCurveStartParam[i] = 0.0;
}

Member Function Documentation

operator=()

DllExport NURBSRuledSurface& operator=

(

const NURBSRuledSurface &

surf

)

Remarks

Assignment operator.

Parameters:

const NURBSRuledSurface& surf

The surface to assign.

SetParent()

DllExport void SetParent	(	int	pnum,
		int	index
	)

Remarks

Sets the index in the NURBSSet of the specified parent object.

Parameters:

int pnum

The parent number: 0 or 1.

int index

The index in the NURBSSet of the specified parent object.

SetParentId()

DllExport void SetParentId	(	int	pnum,
		NURBSId	id
	)

Remarks

Sets the NURBSId of the specified parent.

Parameters:

int pnum

The parent number: 0 or 1.

NURBSId id

The id to set.

GetParent()

DllExport int GetParent

(

int

pnum

)

Remarks

Returns the index in the NURBSSet of the specified parent object.

Parameters:

int pnum

The parent number: 0 or 1.

GetParentId()

DllExport NURBSId GetParentId

(

int

pnum

)

Remarks

Returns the NURBSId of the specified parent. Note that a NURBSId won't be valid until the object has been instantiated in the scene

Parameters:

int pnum

The parent number: 0 or 1.

SetFlip()

DllExport void SetFlip	(	int	pnum,
		BOOL	flip
	)

Remarks

This allows one to control the matching of parent surface normals when creating the ruled surface. For example, normally when you create a ruled surface between two parent curves you don't want a 'bow tie' surface (one with the ends rotated 180 degrees so it crosses on itself in the middle). If you simply match the parent normals you'll get a 'bow tie' surface. To prevent this you use this method to set a state indicating that one or the other should be flipped before it's used. In this way, when the ruled surface is created, a 'bow tie' won't occur.

Parameters:

int pnum

The number of the parent curve: 0 or 1.

BOOL flip

TRUE to match the parent surface normal; FALSE to not match it.

GetFlip()

DllExport BOOL GetFlip

(

int

pnum

)

Remarks

Returns the flip state of the specified parent curve.

Parameters:

int pnum

The number of the parent curve: 0 or 1.

SetCurveStartPoint()

DllExport void SetCurveStartPoint	(	TimeValue	t,
		int	pnum,
		double	startpoint
	)

Remarks

Sets the start point for the specified parent curve. Note: This is only applicable if the parent is a closed curve.

Parameters:

TimeValue t

The time at which to set the start point.

int pnum

The number of the parent curve: 0 or 1.

double startpoint

The start point in the range 0.0 to 1.0.

GetCurveStartPoint()

DllExport double GetCurveStartPoint	(	TimeValue	t,
		int	pnum
	)

Remarks

Returns the start point for the specified parent curve. Note: This is only applicable if the parent is a closed curve.

Parameters:

TimeValue t

The time at which to get the start point.

int pnum

The number of the parent curve: 0 or 1.
