WEEK14
Step01-1
安裝git 開啟GIT bash
cd desktop 進入桌面
git clone 複製你的檔案
cd 進入你的檔案
start . 開啟檔案資料夾
開啟CODEBLOCK
開專案
打專案名稱 選擇檔案存檔位置
選擇自己之前存的Final_Project裡面的freeglut
不用再自己下載啦!!!!!!!!!!!!!!!!!
他跑出來就會生成三個神祕圖形
之後把程式碼全部刪掉，改成以下程式碼
#include <GL/glut.h>
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glutSolidTeapot(0.3);
glutSwapBuffers();
}
int main(int argc,char *argv[])
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE| GLUT_DEPTH);
glutCreateWindow("GLUT Shapes");
glutDisplayFunc(display);
glutMainLoop();
}
就會出現神奇白色茶壺喔
新增一些程式碼
把茶壺變成計時器
到時間會旋轉
#include <GL/glut.h>
float angle =0;
void timer(int t)
{
glutTimerFunc(500,timer,t+1);
angle +=90;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotated(angle,0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char *argv[])
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE| GLUT_DEPTH);
glutCreateWindow("week14");
glutTimerFunc(3000,timer,0);
glutDisplayFunc(display);
glutMainLoop();
}
Step01-2
開一個新專案
設定按鍵來啟動
按越多次轉越快
師大巴士駛到陵墓
#include <GL/glut.h>
float angle =0;
void timer(int t)
{
glutTimerFunc(33,timer,t+1);
angle +=3;
glutPostRedisplay();
}
void keyboard(unsigned char key,int x,int y)
{
glutTimerFunc(0,timer,0);
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotated(angle,0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char **argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE| GLUT_DEPTH);
glutCreateWindow("week14");
///glutTimerFunc(3000,timer,0);
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
glutMainLoop();
}
Step02-1
用Exel來計算角度
先用git備份
git add . 加入你的檔案
git status 確認你的檔案
git config --global user.email "你的Gmail"
git config --global user.name "你的GitHubID"
git commit -m "你的周次"
git push 上傳
Step02-2
開Codeblock的一個新的專案檔
更改成以下程式碼
#include <GL/glut.h>
float angle =0,newAngle=0,oldAngle=0;
float oldX=0;
void timer(int t)
{
if(t<100)glutTimerFunc(33,timer,t+1);
float alpha= t/100.0;
angle = alpha*newAngle+(1-alpha)*oldAngle;
glutPostRedisplay();
}
void keyboard(unsigned char key,int x,int y)
{
glutTimerFunc(0,timer,0);
}
void mouse(int button,int state,int x, int y)
{
if(state==GLUT_DOWN) oldAngle =angle;
if(state==GLUT_UP) newAngle =angle;
oldX =x;
glutPostRedisplay();
}
void motion(int x,int y)
{
angle += x-oldX;
oldX = x;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotated(angle,0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char **argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE| GLUT_DEPTH);
glutCreateWindow("week14");
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
glutMainLoop();
}
這樣就可以讓他做出動畫
先設定一個角度 ，之後再旋轉出另一個新的角度
按空白鍵茶杯就會從第一個角度慢慢轉到第二個角度
Step03-1
用CodeBlock開啟Final_Project.cbp
修改一下程式碼
#include <stdio.h>
#include <GL/glut.h>
#include "glm.h"
GLMmodel * head =NULL;
GLMmodel * body =NULL;
GLMmodel * Ruparm =NULL;
GLMmodel * Rhand =NULL;
int show[4] ={1,1,1,1};
int ID =2;
float teapotX=0,teapotY=0;
FILE * fout =NULL;
FILE * fin =NULL;
void keyboard(unsigned char key,int x,int y)
{
if(key=='0') ID = 0;
if(key=='1') ID = 1;
if(key=='2') ID = 2;
if(key=='3') ID = 3;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
if(head==NULL){
head = glmReadOBJ("model/head.obj");
body = glmReadOBJ("model/body.obj");
Ruparm = glmReadOBJ("model/Ruparm.obj");
Rhand = glmReadOBJ("model/Rhand.obj");
}
glPushMatrix();
glScalef(0.3,0.3,0.3);
glPushMatrix();
glTranslatef(teapotX,teapotY,0);
if(ID==0) glColor3f(1,0,0);
else glColor3f(1,1,1);
if(show[0]) glmDraw(head,GLM_MATERIAL);
glPopMatrix();
if(ID==1) glColor3f(1,0,0);
else glColor3f(1,1,1);
if(show[1])glmDraw(body,GLM_MATERIAL);
if(ID==2) glColor3f(1,0,0);
else glColor3f(1,1,1);
if(show[2])glmDraw(Ruparm,GLM_MATERIAL);
if(ID==3) glColor3f(1,0,0);
else glColor3f(1,1,1);
if(show[3])glmDraw(Rhand,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();
}
int main(int argc,char** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week13");
glutMotionFunc(motion);
glutDisplayFunc(display);
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMainLoop();
}
這樣只要按哪個部位
那個部位就會變成紅色的
Step03-2
修程式碼
#include <stdio.h>
#include <GL/glut.h>
#include "glm.h"
GLMmodel * head =NULL;
GLMmodel * body =NULL;
GLMmodel * Ruparm =NULL;
GLMmodel * Rhand =NULL;
int show[4] ={1,1,1,1};
int ID =2;
float teapotX=0,teapotY=0;
float angle=0;
FILE * fout =NULL;
FILE * fin =NULL;
void keyboard(unsigned char key,int x,int y)
{
if(key=='0') ID = 0;
if(key=='1') ID = 1;
if(key=='2') ID = 2;
if(key=='3') ID = 3;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
if(head==NULL){
head = glmReadOBJ("model/head.obj");

}
glPushMatrix();
glScalef(0.3,0.3,0.3);
glPushMatrix();
///glTranslatef(teapotX,teapotY,0);
if(ID==0) glColor3f(1,0,0);
else glColor3f(1,1,1);
if(show[0]) glmDraw(head,GLM_MATERIAL);
glPopMatrix();
if(ID==1) glColor3f(1,0,0);
else glColor3f(1,1,1);
if(show[1])glmDraw(body,GLM_MATERIAL);
glPushMatrix();
glTranslatef(-1.360000,+0.360000,0);
glRotatef(angle,0,0,1);
glTranslatef(1.360000,-0.360000,0);
if(ID==2) glColor3f(1,0,0);
else glColor3f(1,1,1);
if(show[2])glmDraw(Ruparm,GLM_MATERIAL);
glPushMatrix();
glTranslatef(-1.959999,+0.080000,0);
glRotatef(angle,0,0,1);
glTranslatef(1.959999,-0.080000,0);
if(ID==3) glColor3f(1,0,0);
else glColor3f(1,1,1);
if(show[3])glmDraw(Rhand,GLM_MATERIAL);
glPopMatrix();
glPopMatrix();
glPopMatrix();
glColor3f(0,1,0);
glutSolidTeapot(0.02);
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*3;
teapotY -=(y-oldY)/150.0*3;
printf("glTranslate(%f,%f,0);\n",teapotX,teapotY);
angle += x-oldX;
oldX = x;
oldY = y;
glutPostRedisplay();
}
int main(int argc,char** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week14");
glutMotionFunc(motion);
glutDisplayFunc(display);
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMainLoop();
}
修改手臂的位置
然後把它的位置給顯示出來
