Can someone explain exactly what is meant by "Parameterize" the triangle using baycentric coordinates. I.e. I get how the math plays out to create this equation, but why does it necessarily represent the triangle?

Is this like changing the basis axes?

@echoen2 v1=p1-p0 and v2-p2-p0 define the sides of the triangle and the corresponding coefficients u and v define how far to span those two sides. The end point of the the two spanned vectors v1 and p0 define the three points of a triangle.
