lsy

Query.lsy(n, lfrac)

Y-slope of line n at length fraction lfrac.

Fetches Y-slope of line n at lfrac times the line length along the line. 0. <= lfrac <= 1.. This is equivalent to the rate of change of the y-coordinate with respect to the change of line length.

Parameters:

nint

The line number of the line to be considered.

lfrac: float

The fraction of the length of the line along which to enquire. 0. <= lfrac <= 1.

Returns:

float

The Y-slope.

Return type:

float

Examples

Here we construct a line between the coordinates (0, 0, 0) and (1, 2, 2) then find the Y-slope halfway along the line.
