# 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 p - block pointer fu - first parameter coordinate (u) fv - second parameter coordinate (v)
