step01-1

安裝git

把2023graphicsb 叫下來

cd desktop

git clone https:/github.com/mike7862/2023graphicsb

cd 2023graphicsb

start .

用codeblocks打開 2023graphicsb 裡 Final_Project 的 Final_Project.cbp

更改路徑

變成相對路徑

改成 freeglut\include

改成 freeglut\lib

把freeglut 丟到 Final_Project 專案

把libfreeglut.a 複製

改成 libglut32.a 

用Notpad++打開 gitignore 把 .a 和 .lib 註解掉 

最後要在codeblocks 點 save everything

step01-2

打開git

把剛才修改的檔案上傳到github

step02-1

打開Maya

擷取模型關節

匯出檔案要選 Export selection

檔案要存objexport檔

最後要放在 Final_Project 裡的 model

step02-2

打開codeblocks 

把 glm.h 和 glm.cpp 放入專案

在 codeblocks  裡的專案加入 glm.cpp

程式碼

#include <stdio.h>

#include <GL/glut.h>

#include "glm.h"

GLMmodel * head = NULL;

GLMmodel * body = NULL;

GLMmodel * right_up = NULL;

GLMmodel * right_low = NULL;

float teapotX = 0, teapotY = 0;

FILE * fout = NULL;

FILE * fin = NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    if(head==NULL){

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

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

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

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

        ///glmUnitize(head);

    }

    glPushMatrix();

        glScalef(0.3, 0.3, 0.3);

        glmDraw(head, GLM_MATERIAL);

        glmDraw(body, GLM_MATERIAL);

        glmDraw(right_up, GLM_MATERIAL);

        glmDraw(right_low, GLM_MATERIAL);

    glPopMatrix();

    glutSwapBuffers();

}

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

{

    teapotX=(x-150)/150.0;

    teapotY=(150-y)/150.0;

    if(state==GLUT_DOWN){

        if(fout==NULL) fout = fopen("file4.txt", "w");

        fprintf(fout, "%f %f\n", teapotX, teapotY);

    }

    display();

}

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

{

    if(fin==NULL){

        fclose(fout);

        fin = fopen("file4.txt", "r");

    }

    fscanf(fin, "%f%f", &teapotX, &teapotY);

    display();

}

int main(int argc,char** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week13");

    glutDisplayFunc(display);

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMainLoop();

}

修改程式碼
