Summary
Function: GradientValue( vector beginColor, vector endColor, float percentage );Returns a vector between beginColor and endColor depending on the percentage param.
| • vector | beginColor | – | The Starting Vector Color | |
| • vector | endColor | – | The Ending Vector Color | |
| • float | percentage | – | The Percentage from beginColor to endColor. |
Percentage goes from 0.0 to 1.0 where 0.5 is 50%.
Specification
<lsl> //Created by Ugleh Ulrik
vector GradientValue(vector beginColor, vector endColor, float percentage) {
// If vectors are in SL format (1.0 max) then do a multiplication of 255. // beginColor = beginColor * 255; // endColor = endColor * 255;
float red = beginColor.x + (integer)(percentage * (endColor.x - beginColor.x)); float green = beginColor.y + (integer)(percentage * (endColor.y - beginColor.y)); float blue = beginColor.z + (integer)(percentage * (endColor.z - beginColor.z));
return <red,green,blue>/255;
} </lsl> Note in the return we use /255 to convert a RGB value to an SL Safe Vector. The math assumes it is a normal RGB value during the math, so if it isnt you need to uncomment the multiplication lines.
Examples

// If vectors are in SL format (1.0 max) then do a multiplication of 255. // beginColor = beginColor * 255; // endColor = endColor * 255;
float red = beginColor.x + (integer)(percentage * (endColor.x - beginColor.x)); float green = beginColor.y + (integer)(percentage * (endColor.y - beginColor.y)); float blue = beginColor.z + (integer)(percentage * (endColor.z - beginColor.z));
return <red, green, blue>/255;
}

{
// The following vectors are not SL safe, to use SL Safe Vectors you would do

// I use 0.50 which is half, so I am getting the color between Red and Blue, which is Purple.
vector ColorBetween = GradientValue(Red, Blue, 0.50);
llSetColor(ColorBetween, ALL_SIDES); }
