逃離電腦圖學 Week13

 

改這兩個東西

然後GIT PUSH

再開MAYA 裁切Al.obj
拆成 六個部位 保存

再去第八周 複製這兩個檔案到Final_Project

Add File後加入這幾行

#include "glm.h"

GLMmodel * head = NULL;

GLMmodel * body = NULL;

GLMmodel * lefthand = NULL;

GLMmodel * righthand = NULL;

下面程式碼改成這樣

 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();

加入這串

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);

案0123操作不同部位的顯示

增加滑鼠移動功能

glPushMatrix();

            glTranslatef(teapotX,teapotY,0);

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

        glPopMatrix();

另外加

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();

}

最後面加int main

glutMotionFunc(motion);
