used by the special purpose point compution routines that dont use bezier control points but rather the sabin net directly

void Get_uM(t_uM * uM,int n_simp,double * bary)

the input is the (unnormalized) area based barycentrics to use simply do for (int i=0; i<2*n_simp+3; ++i) pos += uM[i]*local[i]; ---This is the recommended scheme, when no precomputed tables will be used------

t_vector uMCompPoint(t_vector * sabin,int n_simp,double * bary)

the input is the (unnormalized) area based barycentrics and the control points the output is the point position The orthodox scheme -------------------

void MakeBeziers(t_vector * sabin,int n_simp)

t_vector ComputePoint(int n_simp,double * bary)

General purpose routines redirecting, normalization provided

void MakeBeziers_n(t_vector * sabin,int n_simp)

t_vector ComputePoint_n(int n_simp,double * bary)

General purpose routines always using Shoemake

void MakeBeziers_3(t_vector * sabin,int n_simp)

t_vector ComputePoint_3(int n_simp,double * bary)

Special purpose 3 sided patch only

void MakeBeziers_4(t_vector * sabin,int n_simp)

t_vector ComputePoint_4(int n_simp,double * bary)

Special purpose 4 sided patch, expects normalized barys

t_vector ComputePoint_4uv(t_vector * sabin,double u,double v)

Special purpose 4 sided patch only u,v within (0..1)
