Luz que vem de uma direção

Sem localização específica

Luz paralela

Mais forte nas áreas quadradas

Mais fraco nas angulações

O sol

Proveniente de um ponto

Com localização específica

Gera um cone de luz a partir do ponto

Texturas estão associadas a vértices

Vértices são consumidos em figuras de diferentes tipos

size(100, 100, P3D);
noStroke();
PImage a = loadImage("arch.jpg");
beginShape();
texture(a);
vertex(10, 20, 0, 0);
vertex(80, 5, 100, 0);
vertex(95, 90, 100, 100);
vertex(40, 95, 0, 100);
endShape();

Coordenadas de mapeamento de textura podem ser normalizadas

PImage textura, textura2;

void setup () {

size(300,300,P3D);

textura = loadImage("eu.jpg");

textura2 = loadImage("textura.jpg");

}

void draw() {

background(0);

translate(width/2,height/2);

rotateX(map(mouseY,0,height,0, 2*PI));

rotateY(map(mouseX,0,height,0, 2*PI));
