Constructor & Destructor Documentation

◆ OdGiPatternAttribs()

OdGiPatternAttribs::OdGiPatternAttribs ( )

Default constructor for the OdGiPatternAttribs class. Sets surface and transformation to NULL, swap flag to false and u derivative scale to 1.

Member Function Documentation

◆ calcAngleBetweenCurves()

double OdGiPatternAttribs::calcAngleBetweenCurves	(	const OdGeSurface *	pSrf,
		bool	swapUv,
		double	uDerScale,
		const OdGePoint2d &	uvPt,
		const OdGeVector2d &	dir,
		bool	mirror )

Calculates angle between curves.

Parameters

pSrf	[in] Surface.
swapUv	[in] Swap u and v parameters flag.
uDerScale	[in] U derivative scale parameter.
uvPt	[in] Curves starting point in parametric space.
dir	[in] Second curve direction in parametric space.
mirror	[in] Mirror second curve direction flag.

Returns: Angle between curves on surface

Remarks: First curve direction is (1, 0)

◆ calcAttribs()

void OdGiPatternAttribs::calcAttribs	(	const OdGeSurface *	pSrf,
		const OdGePoint2d &	faceFillOrigin,
		double	rotAngle,
		const OdGePoint2dArray &	basePts,
		const OdGeDoubleArray &	angles,
		const OdGeVector2dArray &	offsets,
		const OdInt32Array &	faceList,
		const OdGePoint3dArray &	vertexList,
		const OdGePoint2dArray &	trMidPts,
		const OdGeDoubleArray &	annotationScales,
		const OdGeScale2d &	globalScaleUv,
		bool	swapUv,
		double	uDerScale,
		const OdGeMatrix3d *	pTransfMx )

Calculates all patterns attributes arrays.

Parameters

pSrf	[in] Surface.
faceFillOrigin	[in] Patterns origin.
rotAngle	[in] Global rotation angle for all patterns.
basePts	[in] Array of patterns base points.
angles	[in] Array of patterns angles.
offsets	[in] Array of pattern offsets.
faceList	[in] Array of integers defining triangles.
vertexList	[in] Array of mesh vertices.
trMidPts	[in] Array of mesh triangles middle points in parametric space (uv).
annotationScales	[in] Array of annotation scales.
globalScaleUv	[in] Global scale for u and v parameters.
swapUv	[in] Swap u and v parameters flag.
uDerScale	[in] U derivative scale parameter.
pTransfMx	[in] Pointer to model to world transformation matrix.

Remarks: The arrays basePts, angles, offsets and annotationScales must contain the same number of elements. The array trMidPts must contain the same number as there are triangles. The array vertexList must contain the same number as there are vertices.; The results are stored in arrays fillOriginArr, fillDirectionArr, fillOffsetDirectionArr, fillDashesScaleArr, fillOffsetScaleArr which have the size equal to angles.size() * faceList.logicalLength() / 4.

◆ clear()

void OdGiPatternAttribs::clear ( )

Clears all pattern attributes arrays.

◆ isEmpty()

bool OdGiPatternAttribs::isEmpty ( ) const

Checks if pattern attributes arrays are empty.

Remarks: Returns true if some of arrays is empty.
