shen_week13~~今天好熱

用 git clone將自己2023graphicsb的檔案載下來

剛剛老師講的有點快來不及打步驟

然後將freeglut從老師給我們的資料夾

拉進去我們的專案檔

一樣要複製

然後使用第8周glm的兩個檔案

加入下面的程式碼

#include "glm.h"

GLMmodel * head = NULL;

GLMmodel * body = NULL;

GLMmodel * lefthand = NULL;

GLMmodel * righthand = NULL;

 glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    if(head==NULL){

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

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

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

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

    }

    glPushMatrix();

        glScalef(0.3,0.3,0.3);

        glmDraw(head, GLM_MATERIAL);

        glmDraw(body, GLM_MATERIAL);

        glmDraw(lefthand, GLM_MATERIAL);

        glmDraw(righthand, GLM_MATERIAL);

    glPopMatrix();

    glutSwapBuffers();

更改程式碼

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];

    glutPostRedisplay();

}

下面改這樣

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

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

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

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

利用打數字顯示不同部位~~

接著要增加滑鼠移動的功能

glPushMatrix();

            glTranslatef(teapotX,teapotY,0);

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

        glPopMatrix();

然後加

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();

}

最後 加int main

glutMotionFunc(motion);

就完成了
