CIP Visual Basic.NET documentation for interface "IpfcContour"

Interface IpfcContour

Description

This class describes a contour.

Direct Parent Classes:: IpfcObject

Property Summary


`Property`	`InternalTraversal`	`as IpfcContourTraversal [readonly, optional]`
	Determines if a countour's traversal is internal or external.

Method Summary


`Function`	`EvalArea () as Double`
	Finds the surface area inside the given outer contour, accounting for internal voids.

`Function`	`EvalOutline () as IpfcOutline2D`
	Finds the two-dimensional bounding box of the surface inside the outer contour.

`Function`	`FindContainingContour () as IpfcContour [optional]`
	Finds the innermost contour that encloses the specified contour. If the specified contour is internal, the returned contour will be external, and vice versa.

`Function`	`ListElements () as IpfcEdges`
	Gets an array of edges for the contour.

`Function`	`VerifyUV (Params as IpfcUVParams) as IpfcPlacement`
	Verifies whether the specified UV point lies within the given contour.

Property Detail

Property InternalTraversal as IpfcContourTraversal [readonly, optional]

Determines if a countour's traversal is internal or external.

Method Detail

Function EvalArea () as Double

Finds the surface area inside the given outer contour, accounting for internal voids.

Exceptions thrown (but not limited to):

IpfcXToolkitBadSrfCrv - The input argument is invalid.

Returns:: The contour area

Function EvalOutline () as IpfcOutline2D

Finds the two-dimensional bounding box of the surface inside the outer contour.

Exceptions thrown (but not limited to):

IpfcXToolkitBadSrfCrv - The input argument is invalid.

Returns:: The bounding box, as an array of points

Function FindContainingContour () as IpfcContour [optional]

Finds the innermost contour that encloses the specified contour. If the specified contour is internal, the returned contour will be external, and vice versa.

In case the specified contour is the outermost contour for the surface then null is returned.

Exceptions thrown (but not limited to):

IpfcXToolkitNotFound - The specified contour was not found.

IpfcXToolkitInvalidPtr - The specified pointer is not a solid pointer.

Returns:: The containing contour.

Function ListElements () as IpfcEdges

Gets an array of edges for the contour.

Exceptions thrown (but not limited to):

IpfcXToolkitNotFound - No edges were visited, either because of the filter or for another reason.

Returns:: The list of edges

Function VerifyUV (Params as IpfcUVParams) as IpfcPlacement

Verifies whether the specified UV point lies within the given contour.

Exceptions thrown (but not limited to):

IpfcXToolkitBadSrfCrv - One or more of the input arguments are invalid.

Parameters:

Params

Returns:

The function returns one of the following values:

PLACE_ON_BOUNDARY -- The point is on the contour.
PLACE_OUTSIDE -- The point is outside the contour.
PLACE_INSIDE -- The point is inside the contour.
