◆ Flip()

void ON_MeshTriangle::Flip ( )

Swaps the values of m_vi[1] and m_vi[2]. m_vi[0] is not changed.

◆ GetTriangleNormal() [1/4]

bool ON_MeshTriangle::GetTriangleNormal	(	const class ON_3dPoint *	dV,
		class ON_3dVector &	triangle_normal
	)		const

Compute the triangle normal

Parameters

dV	[in] double precision vertex array for the mesh
fV	[in] float precision vertex array for the mesh
vertex_list	[in] vertex locations
triangle_normal	[out] triangle normal

Returns: true if triangle_normal is valid.
