Hi,

In the below code, why can't I call up the function twice and put different numbers into the variables, when I activate the interpolation ?


import processing.opengl.*;

void setup() {
 size(390, 390, OPENGL);
 background(0);
 frameRate(30);

}

void draw() {
 background(0);
 
 //  -  why can't I call up the function twice and put different numbers into the variables, when I activate the interpolation ?
 if(mouseX> 0 && mouseX<100 && mouseY> 0 && mouseY<100){
   lines(6, 12, 1, 50, 20, 1, 100, 90, 0.3, 0, 0, 250); // lAmt, lDist, sw, tx, ty, tz, lw, speed, smooth, r, g, b
   lines(20, 3, 1, 20, 10, 1, 100, 90, 0.5, 255, 0, 0);
 } else {
   lines(3, 5, 1, 20, 10, 1, 200, 90, 0.3, 0, 0, 255);
   lines(9, 3, 1, 50, 50, 1, 200, 90, 0.5, 255, 20, 0);
 }
}


float ilDist, ilw, itx, ity, itz;
// float ilDist, float ilw, float itx, float ity, float itz

void lines(float lAmt, float lDist, float sw, float tx, float ty, float tz, float lw, float speed, float smooth_, int r, int g, int b) {

 // draw the lines
 pushMatrix();
 translate(itx, ity, itz);
 for(int i=0; i<lAmt; i++){
   stroke(r, g, b);
   //line(0, i*ilDist, ilw, i*ilDist);
   line(0, i*lDist, lw, i*lDist);
 } // end forloop
 popMatrix();
 
 // interpolation
 ilw = ilw * smooth_ + lw * (1.0 - smooth_);
 ilDist = ilDist * smooth_ + lDist * (1.0 - smooth_);
 itx = itx * smooth_ + tx * (1.0 - smooth_);
 ity = ity * smooth_ + ty * (1.0 - smooth_);
 itz = itz * smooth_ + tz * (1.0 - smooth_);
 
 
 
} // end lines1
