Creating 3D sketches on Android
In Chapter 3, Drawing in 3D–Lights, Camera, and Action! you've learned everything about drawing stuff in 3D. In this recipe, we'll take a look at how the third dimension works on your Android device.
How to do it...
You can start by typing the following code into a new sketch. The code is very straightforward. It's a white cube and a colorful quad, rotating at the center of the screen.
void setup()
{
size( displayWidth, displayHeight, P3D );
}
void draw()
{
background( 0 );
translate( width/2, height/2, 0 );
pushMatrix();
rotateY( radians( frameCount ) );
fill( 255 );
noStroke();
box( 100 );
popMatrix();
pushMatrix();
rotateY( radians( frameCount ) );
rotateX( radians( frameCount ) );
beginShape();
fill( 255, 0, 255 );
vertex( -200, -200 );
fill( 0, 255, 0 );
vertex( 200, -200 );
fill( 0, 0, 255 );
vertex( 200, 200 );
fill( 255, 255, 0 );
vertex( -200, 200 );
endShape( CLOSE );
popMatrix();
}
