TranslateRotateScale_demo

A demo to hopefully aid in the understanding of how these calls work. Controller source code will need to be placed under a separate tab.

import java.awt.event.*;

import javax.swing.event.*;

JFrame frame;

float rotX;
float rotY;
float rotZ;

float transX;
float transY;
float transZ;

float myScale = 1;

int XOffset = 0;
int hGap = 0;
int vGap = 0;

void setup() {
  size(800, 800, P3D);
  surface.setTitle("P3D TranslateRotateScale");
  javax.swing.SwingUtilities.invokeLater(new Runnable() {
    public void run() {
      buildControlWnd(); // Builds controls on EventDispatchThread
    }
  }
  );
}

void draw() {
  background(209);
  translate(transX, transY, transZ);
  rotateX(radians(rotX));
  rotateY(radians(rotY));
  rotateZ(radians(rotZ));
  scale(myScale);
  boxGrid(12, 40, 15, 10, 15, 5, 5);
}

void boxGrid(int col, int row, int l, int t, int w, int h, int d) {
  fill(0, 255, 0);
  for (int i = 0; i < col; i++) {
    for (int j = 0; j < row; j++) {
      if (j % 2 == 0) {XOffset = 5;} else {XOffset = 0;}
      int left = l + i*(w + vGap) + XOffset;
      int top = t + j*(h + hGap);
      pushMatrix();
      translate(left, top);
      box(w, h, d);
      popMatrix();     
    }
  }
}
