 week12 

第一堂課

下載 git bash

先輸入 cd desktop(設定桌面路徑)

再輸入https://github.com/wayne00182/2023graphicsa

開啟 Final_project

更改code block 的目錄

將freeglut加進去Final_project的資料夾

執行程式

開啟gitgnore ==>用notepad++

在*.a和*.lib前面加上#

  

第二堂課

開啟MAYA

將模型拆解並在Final_project建立資料夾model

將8-1的檔案也加進去

將glm.cpp 加進去

加入程式碼

#include "glm.h"

GLMmodel * head = NULL;

GLMmodel * body = NULL;

第三堂課

程式碼==>還需要修改

#include <stdio.h>

#include <GL/glut.h>

#include "glm.h"

GLMmodel * head = NULL;

GLMmodel * body = NULL;

GLMmodel * uparmR = NULL;

GLMmodel * lowarmR = NULL;

int show[4] = (1,0,0,0);

float teapotX = 0, teapotY = 0;

FILE * fout = NULL;

FILE * fin = NULL;

void keyboard(unsigned char key, int x, int y){

     if(key=='0') show[0] = ! show[0];

     if(key=='1') show[1] = ! show[1];

     if(key=='2') show[2] = ! show[2];

     if(key=='3') show[3] = ! show[3];

     glutPostRedidplay();

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    if(head==NULL){

        head= glmReadOBJ("model/head.obj");

        body = glmReadOBJ("model/body.obj")

        glmUnitize(head);

    }

glPushMatrix();

    glScaled(0.3, 0.3, 0.3);

    if(show[0]) glmDraw(head, GLM_MATERIAL);

    if(show[1]) glmDraw(body, GLM_MATERIAL);

    if(show[2]) glmDraw(uparmR, GLM_MATERIAL);

    if(show[3]) glmDraw(lowarmR, GLM_MATERIAL);

glPopMatrix();

    glutSwapBuffers();

}

int oldX=0, oldY=0;

void mouse(int button, int state, int x, int y){

     if(state==GLUT_DOWN){

        oldX = x;

        oldY = y;

     }

}

void motion (int x, int y)

{

    teapotX = (x-oldx)/150.0;

    teapotY = (y-oldy)/150.0;

    oldX = x;

    oldY = y;

    glutPostRedisplay();

    }
