How to make triangles to have a different form shape about flat-surface-shader HOT 1 OPEN

Look into the examples folder, you will see the code that display squared shapes with static triangles.

Notice this:

var geometry = new FSS.Plane(600, 400, 6, 4);

Then, use

console.log(geometry);

to see what is inside it.
After that, you will find out "triangles" is inside it.
Continue...

At last you will get:

geometry > triangles > a or b or c > Vertex

So,you can use

geometry.triangles[0].a = new FSS.Vertex(Somenumber,Somenumber,Somenumber);
geometry.triangles[0].b = new FSS.Vertex(Somenumber,Somenumber,Somenumber);
geometry.triangles[0].c = new FSS.Vertex(Somenumber,Somenumber,Somenumber);

to change the position of a point.

I'm not very skilled of this, I was found out that just now. And my English is not good, hope you can get what I mean.

well,I did some trial.Although it's not very good,but at least it's work.
