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)
