WebIf we keep the ﬁrst parameter u constant, then v → ~r(u,v) is a curve on the surface. Similarly, if v is constant, then u → ~r(u,v) traces a curve the surface. These curves are called grid curves. A computer draws surfaces using grid curves. The world of parametric surfaces is intriguing and complex. WebHow do you Parametrize a triangle with vertices? The plane equation is ax+by+cz=d. Substitute each of the vertices to find a=b=c=d. Since (a,b,c) cannot be the null vector we can divide by a to find the equation x+y+z=1. It follows that z=1-x-y giving us the parametrization (x,y,1-x-y). What does it mean to Reparameterize? one fish foundation
