LlGroundContour

Looking for the current API? Open the llGroundContour reference →

Return value notes

Returns a vector that is the ground contour direction below the prim position + offset. The contour is the direction of a contour line at that point, that is the direction in which there is no change in elevation.

Specification

This function is defined as:
vector llGroundContour(vector offset)
{
    vector slope = llGroundSlope(offset);
    return <-slope.y, slope.x, 0.0>;
}

See also: functions

llGround — Gets the ground height
llGroundNormal — Gets the ground normal
llGroundSlope — Gets the ground slope

History

Added in SL 0.9.0
