How can I create a surface from two curves...?

[Masoud]

Hi;

I want to create a surface using two curves like the image below. Both curves are on the same plane (@P.Y = 0).

What king of SOP should I use?

 

 

Thanks for helping.

Hi Masoud,

unless this is an academic exercise, you could just set polyexpand to 'surfaces' or simply use a polyextrude 'inwards'. Otherwise try

• joining each curve so it's one primitive per curve,
• reverse the winding order on one of them so they match, and
• interpolate a geometry of choice between both curves:

vector bb = relbbox(0, v@P);

vector pos_crv_0 = primuv(1, 'P', 0, bb.z);
vector pos_crv_1 = primuv(1, 'P', 1, bb.z);
vector pos_blend = lerp(pos_crv_0, pos_crv_1, bb.x);

v@P = pos_blend;
