ProfileZeroCrossings
Finds the points of a profile at which the profile intersects the x-axis.
Syntax
C++
C#
void avl::ProfileZeroCrossings ( const avl::Profile& inProfile, atl::Array<float>& outZeroCrossings )
Parameters
Name | Type | Default | Description | |
---|---|---|---|---|
inProfile | const Profile& | Input profile | ||
outZeroCrossings | Array<float>& | X coordinates of the locations where the profile crosses the y=0 axis |
Description
The operation assumes linear interpolation between the profile values and finds precise locations at which the profile crosses the horizontal \(y = 0\) axis. For the constant profile sections of value 0 only the integer coordinates of the sampling points in the section are returned.
Examples
inProfile = {-1.0,3.0,0.0,0.0,0.0} | outZeroCrossings = {0.25, 2.0, 3.0, 4.0} |
