課堂作業1

//week08_1_loadShape_shape
size(400, 400, P3D);//step03 要有 OpenGL 3D功能
PShape gundam = loadShape("Gundam.obj");//step01 讀入3D模型
translate(width / 2, height / 2);
pushMatrix();//輩分矩陣
  translate(0, 100);//step05 往下移一點點
  scale(10, -10, 10);//step04 (x, y, z) 把模型放大 上下要倒過來
  shape(gundam, 0, 0);//step02 畫出3D模型
popMatrix();//還原矩陣

課堂作業2
