3D Mesh of Sine Waves from Coding Challenge

Hello,

I had some fun exploring 3D meshes from:
Coding Challenge #11: 3D Terrain Generation with Perlin Noise in Processing

Code < Click here
// 3D Mesh Sine Waves
// v 1.0.1
// GLV 2020-07-22

int rows, cols;
int sp = 10;
int w = 600;
int h = 600;
int col;

float theta;
boolean toggle = true;

void setup() 
	{
  size(600, 600, P3D);

  cols = w/sp;
  rows = h/sp;
  
  colorMode(HSB, 256*2*3, 100, 100); //all hues at full sat and brightness
  background(0);
  }

void draw() 
	{
  background(0);
  lights();
  
  pushMatrix();
  translate(width/2, height/2);
  rotateX(TAU/8);
  translate(-w/2, -h/2 -250, -150);
  
  theta += TAU/1000;
  col += 1;
  
  if (col> 256*2*3-1) col = 0;

  if(toggle)
    { 
    noStroke();
    fill(col, 100, 100);
    }
  else
    {
    stroke(60*256*2*3/360, 100, 100);
    println(hex(color(60*256*2*3/360, 100, 100)));
    noFill();
    }     
    
  for(int y = 0; y< rows; y++)
    {
    beginShape(TRIANGLE_STRIP);
    
    float angley = TAU/20;
    
    for(int x = 0; x < cols; x++)
      {    
      float anglex = TAU/20;
          
      float z1 = 50*sin(x*anglex + theta) + 50*sin(y*angley + theta);
      float z2 =  50*sin(x*anglex + theta) + 50*sin((y+1)*angley + theta);
      
      vertex(x*sp, y*sp, z1);
      vertex(x*sp, (y+1)*sp, z2);
      }
    endShape();  
    }
    popMatrix();
    
  push();  
  fill(256*3*2);
  textSize(30);
  color c = color(col, 100, 100);
  
  text("RED: "     + nfs( (c >> 16 & 0xFF), 3) + 
       "  GREEN: " + nfs(( c >> 8 & 0xFF), 3) +  
       "  BLUE: "+ nfs((c & 0xFF), 3), 40, height-60);    
  pop();
  }

void keyPressed()
  { 
  toggle = !toggle; 
  println(toggle); 
  }

I got it to cycle through all the hues for full sat and brightness in HSB mode; that I had to think about!

That was fun!
