電腦圖學課程week13 叡

Week13-1

前往https://jsyeh.org/3dcg10/下載data、win32

1.用maya開啟Al.obj去裁切模型，把身

體各部分裁切並存檔(Export Selection)

需要用到上周的Final Project，去github複製下來

下載git bash

cd desktop

https://github.com/iamnotCreeper/2023graphicsa

cd 2023graphicsa

start .

#include "glm.h"
GLMmodel * head = NULL;
GLMmodel * body = NULL;
GLMmodel * uparmR = NULL;
GLMmodel * lowarmR = NULL;
int show[4] = {0,1,0,0};
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();
}
float teapotx = 0, teapoty = 0;
FILE * fout = NULL;
FILE * fin = NULL;
void display(){
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
    glScaled(0.2,0.2,0.2);
        /// glTranslatef(teapotx, teapoty, 0);
        /// glutSolidTeapot(0.3);
        if(body == NULL){
            head = glmReadOBJ("Model/head.obj");
            body = glmReadOBJ("Model/wholebody.obj");
            uparmR = glmReadOBJ("Model/uparmR.obj");
            lowarmR = glmReadOBJ("Model/armhandR.obj");
            ///glmUnitize(body);
        }
        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();
}

用CodeBlock打開以後會因為找不到freeglut出現錯誤，

把freeglut放到Final Project中

打開final project

project-properties 更改search directories 改成freeglut/include ,freeglut/lib

把剛剛裁切好的模型檔案裝入資料夾

再把week10的glm.cpp跟glm.h複製到資料夾裡
