1.拿上週的程式
#include <stdio.h>
#include <GL/glut.h>
float diff=2,angle[20]={}; ///把值換成陣列
int angleID=0;
void timer(int t)
{
glutTimerFunc(30,timer,t+1);
angle+=diff;
if(angle>90)diff=-2;
if(angle<0)diff=+2;
glutPostRedisplay();
}
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 display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle,0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle,0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle,0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle,0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char** argv)
{
glutInit( &argc, argv );
glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH );
glutCreateWindow("08160554");
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);
glutMainLoop();
}
2.讓他一次動一個關節
#include <stdio.h>
#include <GL/glut.h>
float diff=2,angle[20]={};
int angleID=0;
void timer(int t)
{
glutTimerFunc(30,timer,t+1);
angle[angleID]+=diff;
if(angle[angleID]>90)diff=-2;
if(angle[angleID]<0)diff=+2;
glutPostRedisplay();
}
void keyboard(unsigned char key,int x,int y)
{
if(key=='0') angleID=0; ///之後timer會改變關節 angle[0]
if(key=='1') angleID=1;
if(key=='2') angleID=2;
if(key=='3') angleID=3;
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[0],0,0,1); ///把angle都改成陣列
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[1],0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[2],0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[3],0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char** argv)
{
glutInit( &argc, argv );
glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH );
glutCreateWindow("08160554");
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);
glutMainLoop();
}
3.用mouse motion操作關節
程式碼如下:
#include <stdio.h>
#include <GL/glut.h>
float diff=2,angle[20]={};
int angleID=0;
void timer(int t)
{
/*glutTimerFunc(30,timer,t+1);
angle[angleID]+=diff;
if(angle[angleID]>90)diff=-2;
if(angle[angleID]<0)diff=+2;
glutPostRedisplay();*/
}
///用mouse motion操作關節
int oldX=0,oldY=0;
void mouse(int button,int state,int x,int y)
///mouse 按下去,記下現在的位置
{
oldX=x;
oldY=y;
}
void motion(int x,int y)
///mouse motion時,會叫這個motion
}
angle[angleID]+=x-oldX;
glutPostRedisplay();
}
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 display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[0],0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[1],0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[2],0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[3],0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char** argv)
{
glutInit( &argc, argv );
glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH );
glutCreateWindow("08160554");
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);
glutMainLoop();
}
4.按S存檔
#include <stdio.h>
#include <GL/glut.h>
float diff=2,angle[20]={};
int angleID=0;
void timer(int t)
{
}
int oldX=0,oldY=0;
void mouse(int button,int state,int x,int y)
{
oldX=x;
oldY=y;
}
void motion(int x,int y)
{
angle[angleID]+=x-oldX;
oldX=x;
glutPostRedisplay();
}
#include <stdio.h>
FILE * fout=NULL;
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;
if(key=='s'){
if( fout == NULL )fout=fopen("angle.txt","w+");
for(int i=0;i<20;i++)printf("%.2f",angle[i]);
printf("\n");
for(int i=0;i<20;i++)fprintf(fout,"%.2f",angle[i]);
fprintf(fout,"\n");
}
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[0],0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[1],0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[2],0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[3],0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char** argv)
{
glutInit( &argc, argv );
glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH );
glutCreateWindow("08160554");
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);
glutMainLoop();
}
5.按r的功能
程式碼如下:
#include <stdio.h>
#include <GL/glut.h>
float diff=2,angle[20]={};
int angleID=0;
void timer(int t)
{
}
///用mouse motion操作關節
int oldX=0,oldY=0;
void mouse(int button,int state,int x,int y)
{///mouse 按下去,記下現在的位置
oldX=x;
oldY=y;
}
void motion(int x,int y)
{///mouse motion時,會叫這個motion
angle[angleID]+=x-oldX;
oldX=x;
glutPostRedisplay();
}
#include <stdio.h>
FILE * fout=NULL;
FILE * fin=NULL;
void keyboard(unsigned char key,int x,int y)
{
if(key=='0') angleID=0;///之後timer會改變關節 angle[0]
if(key=='1') angleID=1;
if(key=='2') angleID=2;
if(key=='3') angleID=3;
if(key=='s'){
if( fout == NULL )fout=fopen("angle.txt","w+");
for(int i=0;i<20;i++)printf("%.2f",angle[i]);
printf("\n");
for(int i=0;i<20;i++)fprintf(fout,"%.2f",angle[i]);
fprintf(fout,"\n");
}
if(key=='r'){
if( fin == NULL )fin=fopen("angle.txt","r");
for(int i=0;i<20;i++)fscanf(fin,"%f",&angle[i]);
glutPostRedisplay();
}
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[0],0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[1],0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[2],0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[3],0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char** argv)
{
glutInit( &argc, argv );
glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH );
glutCreateWindow("08160554");
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);
glutMainLoop();
}
6.改work_dir及加入freeglut.dll
7.讓他自動存檔
程式碼如下:
#include <stdio.h>
#include <GL/glut.h>
float diff=2,angle[20]={};
int angleID=0;
void timer(int t)
{
}
int oldX=0,oldY=0;
void mouse(int button,int state,int x,int y)
{
oldX=x;
oldY=y;
}
#include <stdio.h>
FILE * fout=NULL;
FILE * fin=NULL;
void motion(int x,int y)
{
angle[angleID]+=x-oldX;
oldX=x;
glutPostRedisplay();
if( fout == NULL )fout=fopen("angle.txt","w+");
for(int i=0;i<20;i++)printf("%.2f",angle[i]);
printf("\n");
for(int i=0;i<20;i++)fprintf(fout,"%.2f",angle[i]);
fprintf(fout,"\n");
}
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;
if(key=='s'){
if( fout == NULL )fout=fopen("angle.txt","w+");
for(int i=0;i<20;i++)printf("%.2f",angle[i]);
printf("\n");
for(int i=0;i<20;i++)fprintf(fout,"%.2f",angle[i]);
fprintf(fout,"\n");
}
if(key=='r'){
if( fin == NULL )fin=fopen("angle.txt","r");
for(int i=0;i<20;i++)fscanf(fin,"%f",&angle[i]);
glutPostRedisplay();
}
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[0],0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[1],0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[2],0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[3],0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char** argv)
{
glutInit( &argc, argv );
glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH );
glutCreateWindow("08160554");
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);
glutMainLoop();
}
