Question

Q1. Please use Processing to draw a 3D box using PShape and vertex(x, y, z) instead of using the default box(x, y, z) command. (You need to define your own 8 vertices for the box).

Q2. Recall how we draw a 3D Cone shape in Processing using PShape and vertex(x, y, z), please draw a 3D cylinder using PShade in Processing.

Q3. Now utilize the 3D cylinder, 3D box shape, and Geometric transformations to draw the Lego pieces shown below (HINT: as long as we can construct the single unit piece, we can use Geometric Transformation to construct any other pieces):

Explanation / Answer

1. Creating 3d-bx using Pshape and vertex(x,y,z)

================================Program Below=============================================

PShape box;

void setup(){

box = createShape();

//begin making the box shape

box.beginShape();

//creating a 3d-box of size : 1*1*1

//you can change the verticex and give coordinates according to your wish/requirement

//creating 8 vertices of the box

box.vertex(0,0,0);

box.vertex(1,0,0);

box.vertex(1,1,0);

box.vertex(0,1,0);

box.vertex(0,0,1);

box.vertex(0,1,1);

box.vertex(1,0,1);

box.vertex(1,1,1);

box.endShape(CLOSE); //end drawing the shape

}

void draw(){

//setting up background color for better visiblity of the 3d box

background(51);

//translate here if you want to move the box from origin

//to create the box where the mouse is use below line

//translate(mouseX,mouseY,0);

//create the box using shape method

shape(box);

}
