Vector Gradient

De DigiWiki.

vector gradient(list vectors, float rangestart,  float rangeend, float index)
{
// Originally coded by TigroSpottystripes Katsu
// this function take as input a list containg vectors, a float specifying the min range of the input and another for the end, 
// and finally a float indication which point of the gradient ramp the result will be
 
  // converts the index to the range of the vetors list
  float transfindex = ((index - rangestart)/(rangeend - rangestart)) * (llGetListLength(vectors)- 1);    
 
  integer pos = llFloor(transfindex); //get the position on the list
 
  float firstmulti =  (1-(transfindex-pos)); // the multiplier for the first vector
  float secondmulti = (transfindex-pos); //the multiplier for the second vector
 
  vector firstvec= (llList2Vector(vectors, pos) * firstmulti); //set how much of the first  vector will be passed
  vector secondvec = (llList2Vector(vectors, pos+1) * secondmulti); //same thign but with the next vector
  vector newvec = firstvec + secondvec ; //mix the two
 
  return newvec; //and the cross-fade is done =^.^=
