作業1:畫出鋼彈模型

• 程式碼:

//week08_1_loadShape_shape

size(400,400,P3D);  //(3) 要有P3D的OpenGL 3D 功能

PShape gundam = loadShape("Gundam.obj");  //(1) 讀入3D模型

translate(width/2, height/2);  //放到畫面中心

pushMatrix();  //備份矩陣

  translate(0,100);  //(5)再往下移一點點

  scale(10,-10,10);  //(4)把模型放大 shape(10) 上下要再倒過來

  shape(gundam,0,0);  //(2)畫出3D模型

popMatrix();  //還原矩陣

• 執行結果:

作業2:改成互動模式的程式風格

• 程式碼

//week08_2_PShape_gundam_setup_draw_push_scale_shape_pop

//改成互動模式的程式風格

PShape gundam;

void setup(){

  size(400,400,P3D);

  gundam = loadShape("Gundam.obj");

}

void draw(){

  background(128);

  translate(width/2,height/2+100);

  pushMatrix();

    scale(10,-10,10);

    rotateY(radians(frameCount));

    shape(gundam,0,0);

  popMatrix();

  pushMatrix();

    translate(100,0,0);

    scale(10,-10,10);

    shape(gundam,0,0);

  popMatrix();

}

• 執行結果:
  
  
  

作業3:

• 程式碼:

//week08_3_another_obj_large

PShape gundam;  //要再把 Gundam.obj等檔案拉進來

void setup(){

  size(400,400,P3D);

  gundam = loadShape("FinalBaseMesh.obj");

}

void draw(){

  background(128);

  lights();

  translate(width/2,height/2+100);

  pushMatrix();

    scale(10,-10,10);

    rotateY(radians(frameCount));

    shape(gundam,0,0);

  popMatrix();

}

• 執行結果:

作業4:

• 程式碼:

//week08_4_gundam_body_head

//慢慢把「切割開」的模式，逐一組合起來

//把四個檔案拉進來AO.jpg body.mtl body.obj Diffuse.jpg

PShape body,head;

//頭的兩個檔案 head.obj head.mtl

void setup(){

  size(400,400,P3D);

  body = loadShape("body.obj");

  head = loadShape("head.obj");

}

void draw(){

  background(255);

  translate(width/2, height/2+100);

  sphere(10);

  

  scale(10, -10, 10);

  pushMatrix();

    translate(0, +22.5);  //(3)再掛回原來的地方

    rotate(radians(x));  //(2)轉動

    //translate(x/10,y/10);  //要放在小x,y的座標

    //println(x/10,y/10)//印出座標, 等一下要取上面的數

    translate(0, -22.5);

    shape(head, 0, 0);

  popMatrix();

  shape(body,0,0);

}

float x=0, y=0;

void mouseDragged(){

  x += mouseX -pmouseX;

  y -= mouseY -pmouseY;

}
