Hi everyone,
I am new to Processing and I was playing with 3D rendering in processing. I have a ball move around following the mouse. The scene is lit by a point light. I have some text on the screen that shows the position of the ball in the space. But the texts are affected by the point light as well. I was wondering is there a way to exclude the texts from the lighting?
Below is my code.
Thank you for your help in advance.

Walk w1 = new Walk();
float mouseZ = 0.0;
PFont font;
void setup() {
size(800, 320, OPENGL);
smooth();
noStroke();
fill(255);
font = createFont("SegoeWP", 14);
textFont(font);
textAlign(LEFT);
//pointLight(255, 244, 178, width/2, height/2, 10);
}
void draw() {
background(50);
pointLight(255, 244, 178, width/2, height/2, 100);
if(mousePressed) {
mouseZ -= 1;
} else {
mouseZ = 0;
}
text("x: " + mouseX, 10, 20);
text("y: " + mouseY, 10, 40);
text("z: " + mouseZ, 10, 60);
w1.update(mouseZ);
}
