Lights in 3D
Apr 13^th, 2010, 4:49am

hello
i'm new in programming with Processing tools, i'm writing a simple code to illuminate a 3D scene with a box, my problem is that when I use the functions smooth() and lights() togheter strange lines appears on my box and I don't know how to erase them (or keep them not visible),
the code below is the one i'm working on:(you can just copy and run)

//--------------------------
//--------------------------

float spin = 0.0;

void setup()
{
size(640, 360, P3D);
noStroke();
smooth();
}

void draw()
{
background(51);
lights();
fill(255,0,0);
spin += 0.01;

pushMatrix();
translate(width/2, height/2, 0);
rotateX(PI/9);
rotateY(PI/5 + spin);
box(150);
popMatrix();
}

//--------------------------
//--------------------------

thank you for your attention.

If you run your sketch in OPENGL mode the lines disappear. This is quite normal in my experience.
Code:


import processing.opengl.*;

###
 size(640, 360, OPENGL);
 configureOpenGL();
####

void configureOpenGL(){
  hint(ENABLE_OPENGL_4X_SMOOTH);
  hint(DISABLE_OPENGL_ERROR_REPORT);
}

The configureOpenGL is something I like to include in my opengl sketches (smooth() has no effect on opengl, disabling the error report makes it run a bit quicker)
