BSplineSurface3dQuery Interface
Interface for methods supported by both regular (xyz) and weighted (xyzw) bspline surfaces.
Implemented by
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): 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 |
