DPlane3dByVectors	(	DPoint3dCR	_origin,
		DVec3dCR	_vectorU,
		DVec3d	_vectorV
	)

DPlane3dByVectors

(

DTriangle3dCR

triangle

)

Convert triangle edges to vectors.

DPlane3dByVectors

(

)

origin and X Y axes.

DPlane3dByVectors

(

DEllipse3dCR

ellipse

)

origin and axes from ellipse.

Member Function Documentation

DPoint3d Evaluate	(	double	u,
		double	v
	)		const

Evaluate point on plane at u,v.

DPlane3dByVectors EvaluateTangents	(	double	u,
		double	v
	)		const

Evaluate point and tangents at u,v. (Of course, the tangents are just the originals)

static DPlane3dByVectors FromOriginAndParallelToXY ( DPoint3d  origin, double  sizeU, double  sizeV  )

static

Return a plane parallel to XY from given origin.

static DPlane3dByVectors FromOriginAndParallelToXZ ( DPoint3d  origin, double  sizeU, double  sizeV  )

static

Return a plane parallel to XZ from given origin.

static DPlane3dByVectors FromOriginAndParallelToYZ ( DPoint3d  origin, double  sizeU, double  sizeV  )

static

Return a plane parallel to YZ from given origin.

static DPlane3dByVectors FromOriginAndTargets ( DPoint3dCR  origin, DPoint3dCR  UTarget, DPoint3dCR  VTarget  )

static

Return a plane from orgin and u,v target points.

ValidatedDPlane3d GetDPlane3dWithUnitNormal

(

)

const

Return DPlane3d form with unit normal.

bool GetTransformsUnitZ	(	TransformR	localToWorld,
		TransformR	worldToLocal
	)		const

Return coordinate transforms, with unit perpendicular as Z vector in local to world.

ValidatedDPoint2d ProjectPoint

(

DPoint3dCR

spacePoint

)

const

project spacePoint onto the plane (unbounded)

Returns

u,v coordinates of the projection. This is marked valid in the usual case of independent (nonzero, non-parallel) plane vectors.

Remarks

if the plane vectors are parallel, the returned parameters do a projection to the longer vector, and are marked invalid

if the plane vectors are both zero, the returned parameters are zero and are marked invalid.

bool TransverseIntersection	(	DSegment3dCR	segment,
		DPoint2dR	uv,
		double &	segmentFraction
	)		const

Compute the simple intersection of a segment with the plane.

Returns false in any parallel case (both in-plane and off-plane)
