下載老師給我們week15的專案、程式碼
主題:動畫、內插
放入上週程式碼:
#include <stdio.h>
#include <GLUT/glut.h>
float angle=0, diff=2;
void timer(int t)
{
glutTimerFunc( 30, timer, t+1 );
angle += diff;
if(angle>90) diff = -2;
if(angle<0) diff = +2;
glutPostRedisplay();
}
void display()
{
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glPushMatrix();
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();
glutSolidTeapot( 0.3 );
glutSolidTeapot( 0.3 );
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main( int argc, char** argv )
{
glutInit( &argc, argv );
glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH );
glutCreateWindow( "week15 many angles" );
glutDisplayFunc( display );
glutTimerFunc( 0, timer, 0);
glutMainLoop();
}
1.1修改一下 flot angle 的陣列(鍵盤)
加上angle的程式碼:
#include <stdio.h>
#include <GLUT/glut.h>
float angle[20]={},diff=2;
int angleID=0;///目前20個angle (angle[0],angle[1]...angle[angleID])
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;
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 );
glPushMatrix();
glutSolidTeapot( 0.3 );///身體
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();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char** argv)
{
glutInit( &argc,argv);
glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week16 ");
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);
glutMainLoop();
}
1.2 加上滑鼠控制(希望用滑鼠取代Timer)
#include <stdio.h>
#include <GLUT/glut.h>
float angle[20]={},diff=2;
int angleID=0;///目前20個angle (angle[0],angle[1]...angle[angleID])
void timer(int t)
{
/// glutTimerFunc(30,timer,t+1);
}
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();
}
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 );
glPushMatrix();
glutSolidTeapot( 0.3 );///身體
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 );///左手肘
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[2], 0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot( 0.3 );///右手臂
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[3], 0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot( 0.3 );///右手肘
glPopMatrix();
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char** argv)
{
glutInit( &argc,argv);
glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week16 ");
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);
glutMainLoop();
}
注意:
❗main 裡面也要程式❗
🔎 glutMouseFunc(mouse);
🔎 glutMotionFunc(motion);
1.3 用for迴圈來印出陣列
程式碼:
#include <stdio.h>
#include <GLUT/glut.h>
float angle[20]={},diff=2;
int angleID=0;///有20個angle (angle[0],angle[1]...angle[angleID])
void timer(int t)
{
/// glutTimerFunc(30,timer,t+1);
}
int oldX=0,oldY=0;
void mouse(int button ,int state, int x, int y)
{
oldX=x;
oldY=y;
}
FILE * fout =NULL;
void motion(int x,int y)
{
angle[angleID] += x - oldX;
oldX=x;
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;
if(key=='s')
{
if(fout==NULL)fout=fopen("angle.txt","w+");///加上的for迴圈
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");///到這邊結束
}
}
void display()
{
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glPushMatrix();
glutSolidTeapot( 0.3 );///身體
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 );///左手肘
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[2], 0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot( 0.3 );///右手臂
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[3], 0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot( 0.3 );///右手肘
glPopMatrix();
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char** argv)
{
glutInit( &argc,argv);
glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week16 ");
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);
glutMainLoop();
}
1.4 按鍵 r 開啟檔案
程式碼:
#include <stdio.h>
#include <GLUT/glut.h>
float angle[20]={},diff=2;
int angleID=0;///有20個angle (angle[0],angle[1]...angle[angleID])
void timer(int t)
{
/// glutTimerFunc(30,timer,t+1);
}
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();
}
FILE * fout =NULL;
FILE * fin=NULL; ///新增變數
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') ///按r來開啟檔案
{
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 );
glPushMatrix();
glutSolidTeapot( 0.3 );///身體
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 );///左手肘
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[2], 0,0,1);

glutSolidTeapot( 0.3 );///右手肘
glPopMatrix();
glPopMatrix(); glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char** argv)
{
glutInit( &argc,argv);
glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week16 ");
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);
glutMainLoop();
}
1.5 自動儲存角度與讀取檔案
程式碼:
#include <stdio.h>
#include <GLUT/glut.h>
float angle[20]={}, diff=2;
int angleID=0;
void timer(int t)
{
}
int oldX=0, oldY=0;

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')
{

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 );
glPushMatrix();
glutSolidTeapot( 0.3 );///身體
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[0], 0,0,1);

glutMouseFunc(mouse);
glutMotionFunc(motion);
glutKeyboardFunc(keyboard);
glutDisplayFunc( display );
glutTimerFunc( 0, timer, 0);
glutMainLoop();
}
注意:
讀檔案的程式碼要加空格
