Member Function Documentation

basis()

void GEO::TrglGradient::basis	(	vec3 &	origin,
		vec3 &	X,
		vec3 &	Y,
		vec3 &	Z
	)		const

Returns the orthonormal basis in which gradient computation are performed.

TX()

double GEO::TrglGradient::TX

(

index_t

i

)

const

Returns the coefficients determining the gradient in this triangle.

grad_X = sum_i { TX(i) * vertex(i)-> embedding(prop) } Note: TX(2) == 0

TY()

double GEO::TrglGradient::TY

(

index_t

i

)

const

Returns the coefficients determining the gradient in this triangle.

grad_Y = sum_i { TY(i) * vertex(i)-> embedding(prop) }

vertex()

const vec3& GEO::TrglGradient::vertex

(

index_t

i

)

const

Returns the ith vertex of the triangle.

Parameters

i	is the index of the vertex, which can be one of 0,1,2.
