Expression function

[AndrewVK]

Suppose i have an custom expression function

which returns vector type.

How can i refer to vector components

from within Point SOP?

For example...i want assign this vector to point normal.

ok, the syntax seems to be this:

vector( specify vector )[ specify component id ]

so say I set a global variable that is a vector:

set -g x = `vector("[1,40,23]")`

then I can extract 40 by typing into any parameter field:

vector($x)[1]

Cheers!

Yes, its true for variables, but

its not works for CUSTOM FUNCTIONS like this (megasimplified):

vector solver()

{

a = 0.5;

b = 0.3;

c = 0.1;

vector newN = [a,b,c];

return newN;

}

I cant refer to this function

by typing

solver()[0] in X field

solver()[1] in Y field

solver()[2] in Z field

the problem seems to be in the way you're setting the vector. Try this instead:

vector solver()

{

a = 0.5;

b = 0.3;

c = 0.1;

vector newN = vector3(a,b,c);

return newN;

}

That should fix your woes.

Bingo!!!

Thank You anakin!
