Methods

Name Description
clone(): BSplineSurface3dQuery clone the surface  
cloneTransformed(transform: Transform): BSplineSurface3dQuery clone and transform  
degreeUV(select: UVSelect): number Return the degree in in selected direction (0 for u, 1 for v)  
extendRange(rangeToExtend: Range3d, transform?: Transform): void Extend rangeToExtend so this surface is included.  
fractionToPoint(uFraction: number, vFraction: number): Point3d Evaluate xyz coordinates at fractional parameter u,v  
fractionToRigidFrame(uFraction: number, vFraction: number, result?: Transform): undefined | Transform Evaluate a rigid frame at fractional parameter u,v  
getPointGridJSON(): PackedPointGrid Return control points json arrays.  
isAlmostEqual(other: any): boolean test for nearly equality with other  
isClosable(select: UVSelect): boolean ask if the u or v direction could be converted to periodic form  
isInPlane(plane: Plane3dByOriginAndUnitNormal): boolean Ask if the entire surface is within a plane.  
isSameGeometryClass(other: any): boolean Test if this and other are the same geometry class.  
knotToPoint(uKnot: number, vKnot: number): Point3d Evaluate xyz coordinates at knot values (uKnot, vKnot)  
numPolesTotal(): number return the total number of poles (product of u,v counts)  
numPolesUV(select: UVSelect): number Return the number of poles in selected direction (0 for u, 1 for v)  
numSpanUV(select: UVSelect): number Return the number of bezier spans in selected direction (0 for u, 1 for v)  
numberToUVSelect(value: number): UVSelect turn a numeric variable into a UVSelect (strict 0 or 1).  
orderUV(select: UVSelect): number Return the order in in selected direction (0 for u, 1 for v)  
poleStepUV(select: UVSelect): number Return the step between adjacent poles in selected direction (0 for u, 1 for v)  
reverseInPlace(select: UVSelect): void Reverse one of the parameterization directions.  
tryTransformInPlace(transform: Transform): boolean apply a transform to the surface
