◆ CalcNormal()

bool chrono::ChTriangle::CalcNormal	(	const ChVector3d &	p1,
		const ChVector3d &	p2,
		const ChVector3d &	p3,
		ChVector3d &	N
	)

static

Static utility function to calculate the normal of a triangle in the provided output vector.

Return 'false' if the triangle is degenerated.

◆ PointTriangleDistance()

double chrono::ChTriangle::PointTriangleDistance	(	ChVector3d	B,
		double &	mu,
		double &	mv,
		bool &	is_into,
		ChVector3d &	Bprojected
	)

Given point B, computes the distance from this triangle plane, returning also the projection of point on the plane.

Parameters

B	point to be measured
mu	returns U parametric coord of projection
mv	returns V parametric coord of projection
is_into	returns true if projection falls on the triangle
Bprojected	returns the position of the projected point
