is there a way to do texture mapping in processing? i saw one previous thread mentioned about mapping a world map to a sphere, but unfortunetly the link provided is broken now.
could anyone help me with this?

something like this..
Code:
BImage a;
void setup()
{
size(550,550);
//a 200*200px image - in your data folder.
a = loadImage("florence03.jpg");
}
void loop()
{
translate(width/2, height/2, mouseY);
rotateX(mouseX/10.0);
rotateY(mouseY/10.0);
rotateZ(mouseY-mouseX/10.0);
beginShape(QUADS);
texture(a);
vertex(0,0,0, 0,0); //x,y,z , texture x, texture y
vertex(100,0,0, 200,0);
vertex(100,100,0, 200,200);
vertex(0,100,0, 0,200);
endShape();
}

that's great, thank you very much for your help! one more question, besides within beginShape endShape, is there any other place i can use texture()? what will be a good way to texture circle, ellipse, curved shapes, or sphere? do i need to manually triangulate them to triangles or triangle strips?
thanks.
