China fan

[microvswind]

hi guys.here trouble you again.

i am trying to medelling the chinese fan,my thought is shift the primitive list as second input of wrangle node.then sue the input0 primitive vertex 1&2  and input1 primitive vertex 3&4,but i do not know how to write the vex correctly.

may you kind guys would gime me some tips or snippet code.

appreciate very much.

regards.

change this:

int p2 = i@parm[2];
int p3 = i@parm[0];

to this:

int p2 = i[]@parm[1];
int p3 = i[]@parm[0];

wow,you are my idol.reply so quickly and clearthank you so much.

and here again another question.how to keep undistroting  the uv texture.the texture pic and hip is attatched below.

Hi, maybe this gives you some ideas.

Hi,

You can use the circle with xyzdist() to get uv coordinates. The x coordinate can be used directly (but should be transformed by fit function to match 0 to 1). The y-value should be 0 or 1 (0 if close to circle and 1 if not).

On the other hand, if you create the surface parametrically you can set the uv-coordinates directly.

One way might be using skin from a set curves (check Konstantins example) another method maybe using two guide curves to interpolate the inbetween values.

P.S: get uvxmin, uvxmax automatically

And here is a more sophisticated version using VEX.

ok here's my go...dunno much about UV tbh...

I have created a video breakdown on one of my approaches:
