今天一開始老師講解期末作業要如何繳交及評分
我們會用sli.do這個投票網站進行投票
每個人都可以給1~5分
期末作業的分數就以此而定
然後老師開始幫我們複習並整合期末作業要怎麼做

圖學筆記week16
今天老師教我們alpha內插公式
angle=alpha*新+(1-alpha)*舊
這樣才能讓動畫跑得更加順暢
並且也用excel示範了一次
然後我們把上次的程式碼複製過來並進行修改
可以看到之前會卡卡的動作，現在變得非常流暢
#include <GL/glut.h>
#include <stdio.h>
float angle[20], oldX=0;
int angleID=0;
FILE * fout = NULL, * fin = NULL;
void myWrite(){///每呼叫一次myWrite()
if( fout == NULL ) fout = fopen("file.txt", "w+");
for(int i=0; i<20; i++){
printf("%.1f ", angle[i] );///小黑印出來
fprintf(fout, "%.1f ", angle[i] );///檔案印出來
}///印出20個數字
printf("\n");///每呼叫一次, 小黑跳行
fprintf(fout, "\n");///每呼叫一次, 檔案也跳行
}///這裡老師沒有fclose
float Newangle[20],Oldangle[20];
void myRead(){
if( fout != NULL ) { fclose(fout); fout=NULL; }
if( fin == NULL ) fin = fopen("file.txt", "r");
for(int i=0; i<20; i++){
Oldangle[i]=Newangle[i];
fscanf(fin, "%f", &Newangle[i] );
}
glutPostRedisplay();///重畫畫面
}
void myinterporlate(float alpha){
for(int i=0;i<20;i++){
angle[i]=alpha * Newangle[i] + (1-alpha) * Oldangle[i];
}
}
int t=0;
void keyboard(unsigned char key, int x, int y){
if( key=='p' ){
if(t%30==0) myRead();
myinterporlate((t%30)/30.0);
glutPostRedisplay();
t++;

if( key=='3' ) angleID=3;
}
void mouse(int button, int state, int x, int y){
oldX = x;
}
void motion(int x, int y){
angle[angleID] += (x-oldX);
///myWrite();
oldX = x;
glutPostRedisplay();
}
void display()

}
不過這樣還是需要按住P才能讓他播放，我們要改成按一下就可以自動播放
所以我們要加上timer
#include <GL/glut.h>
#include <stdio.h>
float angle[20], oldX=0;
int angleID=0;
FILE * fout = NULL, * fin = NULL;
void myWrite(){///每呼叫一次myWrite()

fprintf(fout, "%.1f ", angle[i] );///檔案印出來
}///印出20個數字
printf("\n");///每呼叫一次, 小黑跳行
fprintf(fout, "\n");///每呼叫一次, 檔案也跳行
}///這裡老師沒有fclose
float Newangle[20],Oldangle[20];
void myRead(){
if( fout != NULL ) { fclose(fout); fout=NULL; }
if( fin == NULL ) fin = fopen("file.txt", "r");
for(int i=0; i<20; i++){
Oldangle[i]=Newangle[i];
fscanf(fin, "%f", &Newangle[i] );
}
glutPostRedisplay();///重畫畫面
}
void myinterporlate(float alpha){
for(int i=0;i<20;i++){
angle[i]=alpha * Newangle[i] + (1-alpha) * Oldangle[i];
}
}
void timer(int t){
if(t%50==0) myRead();
myinterporlate((t%50)/50.0);
glutPostRedisplay();
glutTimerFunc(20,timer,t+1);
}
void keyboard(unsigned char key, int x, int y){
if( key=='p' ){
myRead();
glutTimerFunc(0,timer,0);
///myinterporlate((t%30)/30.0);

if( key=='s' ) myWrite();///調好動作,才Save存檔
if( key=='r' ) myRead();
if( key=='0' ) angleID=0;
if( key=='1' ) angleID=1;
if( key=='2' ) angleID=2;
if( key=='3' ) angleID=3;
}
void mouse(int button, int state, int x, int y){
oldX = x;
}
void motion(int x, int y){
angle[angleID] += (x-oldX);
///myWrite();
oldX = x;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glColor3f(1,1,1);
glRectf( 0.3, 0.5, -0.3, -0.5);

glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);
glutMainLoop();
}
由於我們接下來要學攝影機
所以老師要我們先打開projection.exe檔案來看看
我們把一開始的範例程式碼複製起來
然後全部刪掉開始修改
把基礎10行程式打好
再加上reshape函式
#include <GL/glut.h>
void reshape(int w,int h)
{
float ar = (float) w/(float) h;
glViewport(0,0,w,h);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluPerspective(60,ar,0.1,100);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
gluLookAt(0,0,3,
0,0,0,
0,1,0);
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glutSolidTeapot(1);
glutSwapBuffers();
}
int main(int argc,char ** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week16");
glutDisplayFunc(display);
glutReshapeFunc(reshape);
glutMainLoop();
}
可以使用滑鼠拖動來改變視角
#include <GL/glut.h>
void reshape(int w,int h)
{
float ar = (float) w/(float) h;
glViewport(0,0,w,h);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluPerspective(60,ar,0.1,100);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
gluLookAt(0, 0, 3,
0, 0, 0,
0, 1, 0);
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glutSolidTeapot(1);
glutSwapBuffers();
}
void motion(int x,int y){
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
gluLookAt((x-150)/150.0,(y-150)/150.0,3,
0 , 0, 0,
0, 1, 0);
glutPostRedisplay();
}
int main(int argc,char ** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week16");
glutMotionFunc(motion);
glutDisplayFunc(display);
glutReshapeFunc(reshape);
glutMainLoop();
}

圖學week15
今天一開始我們先學播聲音
因為沒有音檔，所以一開始應該會播錯誤訊息的音效
然而可能程式會錯誤無法播放
就必須在compilier>linker裡設定winmm
然後是MP3檔 要先去moodle下載CMP3_MCI.h
才能播放
#include <stdio.h>
#include "CMP3_MCI.h"
CMP3_MCI mp3;
int main()
{
mp3.Load("07042111.mp3");
mp3.Play();
printf("隨便輸入數字程式就卡住了: ");
int N;
scanf("%d",&N);
}
然後我們把上週教的動畫程式碼複製過來
因為上週教的程式會動得很慢，所以我們要改善它
把myWrite()註解掉，在keyboard裡新增save的程式
#include <GL/glut.h>
#include <stdio.h>
float angle[20],oldX=0;
int angleID=0;
FILE * fout = NULL, * fin = NULL;
void myWrite()
{
if(fout == NULL)fout=fopen("file.txt","w+");
for (int i=0;i<20;i++)
{
printf("%.1f ",angle[i]);
fprintf(fout,"%.1f ",angle[i]);
}
printf("\n");
fprintf(fout,"\n");
}
void myRead()
{
if(fout != NULL){fclose(fout);fout=NULL;}
if(fin == NULL)fin=fopen("file.txt","r");
for(int i=0;i<20;i++)
{
fscanf(fin,"%f",&angle[i]);
}
glutPostRedisplay();
}
void keyboard(unsigned char key,int x, int y)
{
if(key=='s')myWrite();
if(key=='r')myRead();
if(key=='0')angleID=0;
if(key=='1')angleID=1;
if(key=='2')angleID=2;
if(key=='3')angleID=3;
}
void mouse(int button,int state,int x,int y )
{
oldX=x;
}
void motion(int x,int y)
{
angle[angleID] += (x-oldX);
///myWrite();
oldX=x;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(1,1,1);
glRectf(0.3,0.5,-0.3,-0.5);
glPushMatrix();
glTranslatef(0.3,0.4,0);
glRotatef(angle[0],0,0,1);
glTranslatef(-0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(0.3,0.5,0.7,0.3);
glPushMatrix();
glTranslatef(0.7,0.4,0);
glRotatef(angle[1],0,0,1);
glTranslatef(-0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(0.7,0.5,1.0,0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(-0.3,0.4,0);
glRotatef(angle[2],0,0,1);
glTranslatef(+0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(-0.3,0.5,-0.7,0.3);
glPushMatrix();
glTranslatef(-0.7,0.4,0);
glRotatef(angle[3],0,0,1);
glTranslatef(+0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(-0.7,0.5,-1.0,0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
///glutInitWindowSize(600,600);
glutCreateWindow("week15");
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);
glutMainLoop();
}

今天一開始老師教我們利用指標fout寫檔案
執行程式後到目標資料夾就會看到多了一個file.txt檔案
然後是用fscanf來讀檔
#include <stdio.h>
int main()
{///檔案指標fout 開啟檔案(檔名,write模式)
FILE * fout = fopen("file.txt","w+");
fprintf(fout,"3.1415926\n");
fclose(fout);///關閉檔案
float angle=0;
FILE * fin = fopen("file.txt","r");
fscanf(fin,"%f",&angle);
printf("讀到了角度:%f",angle);
fclose(fin);
}
然後就可以搭配上周的程式碼
當手臂轉動時就會寫出座標
加上跳行讓他更好看
然後利用讀檔就可以讓他跑動畫
先手動讓他記錄好之後按住R就可以讓他跑出剛剛做的動作
#include <GL/glut.h>
#include <stdio.h>
float angle[20],oldX=0;
int angleID=0;
FILE * fout = NULL, * fin = NULL;
void myWrite()
{
if(fout == NULL)fout=fopen("file.txt","w+");
for (int i=0;i<20;i++)
{
printf("%.1f ",angle[i]);
fprintf(fout,"%.1f ",angle[i]);
}
printf("\n");
fprintf(fout,"\n");
}
void myRead()
{
if(fout != NULL){fclose(fout);fout=NULL;}
if(fin == NULL)fin=fopen("file.txt","r");
for(int i=0;i<20;i++)
{
fscanf(fin,"%f",&angle[i]);
}
glutPostRedisplay();
}
void keyboard(unsigned char key,int x, int y)
{
if(key=='r')myRead();
if(key=='0')angleID=0;
if(key=='1')angleID=1;
if(key=='2')angleID=2;
if(key=='3')angleID=3;
}
void mouse(int button,int state,int x,int y )
{
oldX=x;
}
void motion(int x,int y)
{
angle[angleID] += (x-oldX);
myWrite();
oldX=x;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(1,1,1);
glRectf(0.3,0.5,-0.3,-0.5);
glPushMatrix();
glTranslatef(0.3,0.4,0);
glRotatef(angle[0],0,0,1);
glTranslatef(-0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(0.3,0.5,0.7,0.3);
glPushMatrix();
glTranslatef(0.7,0.4,0);
glRotatef(angle[1],0,0,1);
glTranslatef(-0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(0.7,0.5,1.0,0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(-0.3,0.4,0);
glRotatef(angle[2],0,0,1);
glTranslatef(+0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(-0.3,0.5,-0.7,0.3);
glPushMatrix();
glTranslatef(-0.7,0.4,0);
glRotatef(angle[3],0,0,1);
glTranslatef(+0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(-0.7,0.5,-1.0,0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
///glutInitWindowSize(600,600);
glutCreateWindow("week14");
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);
glutMainLoop();
}
然後老師教我們timer
#include <GL/glut.h>
#include <stdio.h>
void timer(int t)
{
printf("起床,現在時間: %d\n",t);
glutTimerFunc(1000,timer,t+1);
}
void display()
{
}
int main(int argc,char ** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week14_timer");
glutTimerFunc(5000,timer,0);
glutDisplayFunc(display);
glutMainLoop();
}
每跳一次文字就會響一次音效
#include <GL/glut.h>
#include <stdio.h>
#include <mmsystem.h>
void timer(int t)
{
printf("我起床了! %d\n",t);
PlaySound("do.wav",NULL,SND_ASYNC);
glutTimerFunc(1000,timer,t+1);
}
void display()
{
}
int main(int argc,char ** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week14_timer");
glutTimerFunc(5000,timer,0);
glutDisplayFunc(display);
glutMainLoop();
}
2022年5月17日 星期二
week13
這周一開始老師先教我們畫長方形
用glRectf加上座標來畫出長方形
#include <GL/glut.h>
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glRectf(0.3,0.5,-0.3,-0.5);
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutInitWindowSize(600,600);
glutCreateWindow("week13 rect");
glutDisplayFunc(display);
glutMainLoop();
}
然後我們把手臂的旋轉中心放在正中心
可以看到手臂位置跑到中心點了
這時候可以加上rotate讓手臂旋轉
然後再加上Translatef讓手臂回到原來的位置
#include <GL/glut.h>
float angle=45;
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(1,1,1);
glRectf(0.3,0.5,-0.3,-0.5);
glPushMatrix();
glTranslatef(0.3,0.4,0);
glRotatef(angle,0,0,1);
glTranslatef(-0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(0.3,0.5,0.7,0.3);
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
///glutInitWindowSize(600,600);
glutCreateWindow("week13 rect");
glutDisplayFunc(display);
glutMainLoop();
}
然後我們加上mouse motion
讓手臂能在滑鼠按住時跟著轉動
然後我們要畫第二個關節
然後如果要畫左手臂
就只要把程式複製下來，把X座標的正負顛倒就可以了
#include <GL/glut.h>
float angle=0,oldX=0;
void mouse(int button,int state,int x,int y )
{
oldX=x;
}
void motion(int x,int y)
{
angle += (x-oldX);
oldX=x;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(1,1,1);
glRectf(0.3,0.5,-0.3,-0.5);
glPushMatrix();
glTranslatef(0.3,0.4,0);
glRotatef(angle,0,0,1);
glTranslatef(-0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(0.3,0.5,0.7,0.3);
glPushMatrix();
glTranslatef(0.7,0.4,0);
glRotatef(angle,0,0,1);
glTranslatef(-0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(0.7,0.5,1.0,0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(-0.3,0.4,0);
glRotatef(angle,0,0,1);
glTranslatef(+0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(-0.3,0.5,-0.7,0.3);
glPushMatrix();
glTranslatef(-0.7,0.4,0);
glRotatef(angle,0,0,1);
glTranslatef(+0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(-0.7,0.5,-1.0,0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
///glutInitWindowSize(600,600);
glutCreateWindow("week13 rect new");
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);
glutMainLoop();
}
當按下鍵盤就可以旋轉對應的關節
#include <GL/glut.h>
float angle[20],oldX=0;
int angleID=0;
void keyboard(unsigned char key,int x, int y)
{
if(key=='0')angleID=0;
if(key=='1')angleID=1;
if(key=='2')angleID=2;
if(key=='3')angleID=3;
}
void mouse(int button,int state,int x,int y )
{
oldX=x;
}
void motion(int x,int y)
{
angle[angleID] += (x-oldX);
oldX=x;
glutPostRedisplay();
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(1,1,1);
glRectf(0.3,0.5,-0.3,-0.5);
glPushMatrix();
glTranslatef(0.3,0.4,0);
glRotatef(angle[0],0,0,1);
glTranslatef(-0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(0.3,0.5,0.7,0.3);
glPushMatrix();
glTranslatef(0.7,0.4,0);
glRotatef(angle[1],0,0,1);
glTranslatef(-0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(0.7,0.5,1.0,0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(-0.3,0.4,0);
glRotatef(angle[2],0,0,1);
glTranslatef(+0.3,-0.4,0);
glColor3f(1,0,0);
glRectf(-0.3,0.5,-0.7,0.3);
glPushMatrix();
glTranslatef(-0.7,0.4,0);
glRotatef(angle[3],0,0,1);
glTranslatef(+0.7,-0.4,0);
glColor3f(0,1,0);
glRectf(-0.7,0.5,-1.0,0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
///glutInitWindowSize(600,600);
glutCreateWindow("week13 rect new");
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);

week11
#include <opencv/highgui.h>
int main()
{ /// Ipl 是 Intel performance library 的縮寫
IplImage * img = cvLoadImage("data/Diffuse.jpg"); //讀圖
cvShowImage("week11", img); //秀圖
cvWaitKey(0); //等任意鍵繼續
}
然後我們去複製前兩周教的程式碼
就可以讓茶壺套用gundum材質
#include <opencv/highgui.h>
#include <opencv/cv.h>
#include <GL/glut.h>
int myTexture(char * filename)
{
IplImage * img = cvLoadImage(filename); ///OpenCV讀圖
cvCvtColor(img,img, CV_BGR2RGB); ///OpenCV轉色彩 (需要cv.h)
glEnable(GL_TEXTURE_2D); ///1. 開啟貼圖功能
GLuint id; ///準備一個 unsigned int 整數, 叫 貼圖ID
glGenTextures(1, &id); /// 產生Generate 貼圖ID
glBindTexture(GL_TEXTURE_2D, id); ///綁定bind 貼圖ID
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖T, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖S, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); /// 貼圖參數, 放大時的內插, 用最近點
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); /// 貼圖參數, 縮小時的內插, 用最近點
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);
return id;
}
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_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week11 gundum");
glutIdleFunc(display);
glutDisplayFunc(display);
myTexture("data/Diffuse.jpg");
glEnable(GL_DEPTH_TEST);
glutMainLoop();
}
然後使用pmodel秀出gundam模型
#include <opencv/highgui.h>
#include <opencv/cv.h>
#include <GL/glut.h>
#include "glm.h"
GLMmodel * pmodel = NULL;
int myTexture(char * filename)
{
IplImage * img = cvLoadImage(filename); ///OpenCV讀圖
cvCvtColor(img,img, CV_BGR2RGB); ///OpenCV轉色彩 (需要cv.h)
glEnable(GL_TEXTURE_2D); ///1. 開啟貼圖功能
GLuint id; ///準備一個 unsigned int 整數, 叫 貼圖ID
glGenTextures(1, &id); /// 產生Generate 貼圖ID
glBindTexture(GL_TEXTURE_2D, id); ///綁定bind 貼圖ID
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖T, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖S, 就重覆貼圖
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); /// 貼圖參數, 放大時的內插, 用最近點
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); /// 貼圖參數, 縮小時的內插, 用最近點
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);
return id;
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
///glutSolidTeapot(0.3);
if(pmodel == NULL){
pmodel = glmReadOBJ("data/Gundam.obj");
glmUnitize(pmodel);
glmFacetNormals(pmodel);
glmVertexNormals(pmodel,90);
}
glmDraw(pmodel,GLM_TEXTURE);
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week11 gundam");
glutIdleFunc(display);
glutDisplayFunc(display);
myTexture("data/Diffuse.jpg");
glEnable(GL_DEPTH_TEST);
glutMainLoop();
}
