Summary
Function: vector pLin( list v, float t, integer Loop );
Linearly interpolates between two vector points in a list of vectors that define a path.
Returns a vector
| • list | v | |||
| • float | t | – | Ranges between [0, 1] | |
| • integer | Loop | – | Whether the list is a curved line or loops into a closed shape. |
Specification
vector pLin(list v, float t, integer Loop) {
integer l = llGetListLength(v); t *= l-1;
integer f = llFloor(t); t -= f;
return llList2Vector(v,pIndex(f,l,Loop))*(1-t) + llList2Vector(v,pIndex(f+1,l,Loop))*t;
}
integer pIndex( integer Index, integer Length, integer Loop) {
if(Loop) return Index % Length;
if(Index < 0) return 0;
if(Index > --Length) return Length;
return Index;
