Week14
Week 14-1.1
Step 1：先下載並安裝Git
Step 2：打開Git Bash打下列的指令
指令：
cd desktop
git clone 你的網址
cd 剛剛下載的目錄
Step 3：打開CodeBlock，並打開GLUT project
Step 4：將下列程式碼複製進GLUT project中
程式碼：
#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();
glRotatef(angle,0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char *argv[])
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week14");
glutTimerFunc(3000,timer,0);
glutDisplayFunc(display);
glutMainLoop();
}
Step 5：觀察圖片的變動情況，完成！
Week 14-1.2
將上個程式碼增加幾行程式片段
Step 1：使用 Week14-1.1的程式碼
Step 2：在 time()和display()之間新增一行board函式
函式：
void keyboard(unsigned char key,int x,int y)
{
glutTimerFunc(0,timer,0);
}
Step 3：在main()中，將glutTimerFunc()修改為下列程式碼
程式碼：
glutKeyboardFunc(keyboard);
Step 4：觀察程式變動情況，完成！
Week 14-2.1
Step 1：先開啟一個Excel檔案
Step 2：輸入資料：
在A1輸入【timer】，並由上到下打上0~20
在B2格打上：
=A2/20
並點右下角的點點下拉至B22，可自動套用該公式並對照每格，做函式的自動套用及計算
把【舊的角度】打在C1，並從C2~C22打上74
在D1打上【新的角度】
在E1打上新的角度，並在E2打上：
=B2*D2+(1-B2)*C2
並按住右下角的方點，下拉至E22
完成後如下圖：
Step 3：將檔案儲存
將檔案使用Git指令備份到Github上
Git指令：
git add .
git config --gloabl user.email "你的gite mail"
git config --global user.name"你的git 名字"
git commit -m"欲輸入的文字"
git push
Week 14-2.2
Step 1：開啟CodeBlock，並開啟GLUT project
Step 2：將下列程式碼複製並貼上至GLUT project
程式碼：
#include<GL/glut.h>
float angle =0,newangle,oldangle;
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();
glRotatef(angle,0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char *argv[])
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week14");
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
glutMainLoop();
}
按下空白鍵茶壺就會慢慢轉動角度
Step 14-3
Step 1：開啟CodeBlock，開啟Final_project.cbp
Step 2：如此Final_project便會被匯入CodeBlock中
Step 3：將程式碼修改如下
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();
}
如此，只要按某個部位，該部位就會變成紅色的
