Project Description
DRAW PARAMETRIC SURFACES X=F(U,V), Y=G(U,V), Z=H(U,V) To visualize such a surface, you may first fix the U parameter and to make V parameter vary between a convenient interval. This draws a curve in space. For each value of U in its interval, we obtain another curve in space. Altogether, they form the U curves family. By inversing the position of U and V, we obtain the V curves family. The intersection of these two families forms a sort of patchwork that allows visualizing the surface. This method is suitable to draw such surfaces as sphere, ellipsoid, torus, hyperboloid, etc. It is not compatible with the algorithm to remove hidden sections as used in project Surfaces. Any idea ?
