extrude.block.param.pos

Syntax

v = extrude.block.param.pos(p,fu,fv)

The function only applies to regular (3- or 4-sided) blocks with structured mesh.

Get a 2D position vector ($x$,$y$) within block p which corresponds to a parametrized location with parameters u and v. The parameters are floating point values between 0 and 1.

Returns:

v - 2D vector ($x$,$y$) position

Arguments:

p - block pointer

fu - first parameter coordinate (u)

fv - second parameter coordinate (v)
