Bézier triangle A quadratic (formula_3) Bézier triangle features 6 control points which are all located on the edges. The cubic (formula_4) Bézier triangle is defined by 10 control points and is the lowest order Bézier triangle that has an internal control point, not located on the edges. In all cases, the edges of the triangle will be Bézier curves of the same degree. A cubic Bézier triangle is a surface with the equation where α, β, γ, αβ, αβ, βγ, βγ, αγ, αγ and αβγ are the control points of the triangle and s, t, u (with 0 ≤ s, t, u
