### 

第一步:先把上次week10-1TRT_sample_mybody_arm的程式

第二步:搭出TRT的程式

第三步:把TRT註解掉,在從下到到(1)(2)

(3)試著逐一解鎖

### week11-1 again

****程式碼:

#include <GL/glut.h>

void myBody(){

    glColor3f(1,0,0);///red body

    glutWireCube(0.6);///cube

}

void myArm(){

    glPushMatrix();

    glColor3f(0,1,0);/// green arm

    glScalef(1.5,0.5,0.5); ///weight 1.5 high 0.5

    glutWireCube(0.3);///

    glPopMatrix();

}

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

     ///glTranslatef(-0.6,+0.3,0);

    myBody();

    glPopMatrix();

    glPushMatrix();

     glTranslatef(0.3,0.3,0);///(3)掛到肩上

     glRotatef(angle++,0,0,1);///(2)轉動

     glTranslatef(0.45/2,0,0);///(1)把旋轉中心,放在正中心上

    ///glTranslatef(+0.0,+0.3,0);

    myArm();

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);///140

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);///143

     glutCreateWindow("week11_1glutSolid系列");///145

    glutIdleFunc(display);

     glutDisplayFunc(display);///148

     glutMainLoop();///174

}

### week11-1_onj_gumdam

1:安裝opencv2.1,記得要Add path,裝在預設目錄 C:\openCV2.1

2:重開codeblocks,setting-Compiler,設定search director 要設兩個(include lib),linker setting 要設三個

### 用maya裁切模式

1:先開maya,import剛剛week11-2的Gundam.obj模型

2:裁切,剩下右手,存檔hand.obj(檔案格式OBJExoprter)

3:裁切,剩下左手,存檔成hand1.obj(檔案格式OBJExoprter)

### week11-3 ibj_gundam_hand_hand1
