Summary
Function: vector GradientValue( vector start, vector end, float percentage );Returns a vector that is the color vector between start and end depending upon percentage if the vector between can be calculated, else returns <-1, -1, -1>.
| • vector | start | – | Gradient start color | |
| • vector | end | – | Gradient end color | |
| • float | percentage | – | Percentage in the range (0.0 to 100.0) from start to end |
Specification
<lsl> // Created by Ugleh Ulrik
vector GradientValue(vector start, vector end, float percentage) {
list colorParams = [start.x, start.y, start.z, end.x, end.y, end.z];
if (percentage < 0.0
Examples
<lsl> vector GradientValue(vector start, vector end, float percentage) {
list colorParams = [start.x, start.y, start.z, end.x, end.y, end.z];if (percentage < 0.0
