GroundNormal

llGroundNormal

Summary

Function: vector llGroundNormal( vector offset );

222	Function ID
0.0	Forced Delay
10.0	Energy

Returns a vector that is the ground normal from the current position + offset.

• vector

offset

The requested position needs to be in the same sim.

Specification

This function is defined as: <lsl> vector llGroundNormal(vector offset) {

   vector slope = llGroundSlope(offset);
   return <slope.x, slope.y, 1.0>;

} </lsl>

Caveats

• Despite the name, llGroundNormal DOES NOT RETURN A NORMAL UNIT VECTOR!!! If your calculation requires a unit normal (for example if you are using the result as an argument to llAxes2Rot) then you must force it to be a unit normal with llVecNorm(llGroundNormal(offset));
